House extension with stepping stones leading inside by Haberstroh Schneider Architekten

Swiss firm Haberstroh Schneider Architekten has extended a house in Basel by adding a chain of three rooms, creating a new semi-enclosed courtyard that is filled with stepping stones (+ slideshow).

Haus von Arx by Haberstroh Schneider Architekten

Haberstroh Schneider Architekten removed a number of previous extensions to reduce Haus von Arx to its original size, before adding the new volumes to the western edge of the building to provide a home office and library.

The architects designed the courtyard and stepping stones to allow the family to move between the existing house and the extension.

“We wanted this area, as small as it is, to be a space for contemplation, where movements slow down and one is not able to rush through,” they told Dezeen.

A sheltered porch creates a separate entrance for the extension, leading through to a library with floor-to-ceiling bookshelves, and then on into the small office.

The architects also added a guest bedroom and bathroom above the house’s existing garage, as well as a new swimming pool and pavilion on the east side of the building.

The exterior of the extensions is finished in white render, contrasting with the grainy grey-painted facade of the main house.

Existing living rooms and bedrooms were left to their original layout, but a curving staircase with iron balustrades was painted in a deep shade of green.

“We wanted to enhance the very elegant stairs so we decided to paint them a dark green that, besides contrasting with the rest of the house, is a colour used traditionally on the interior of historical, wealthy and important houses,” added the architects.

Here’s a project description from the architects:


Haus von Arx

The former building – originally built in 1951 – had been extended, converted and renovated several times over the past years. As a consequence, it presented itself as an accumulation of heterogeneous rooms and styles.

Haus von Arx by Haberstroh Schneider Architekten

In discussions with the new owner we developed the idea of reducing the building to both its original size and primary qualities.

Haus von Arx by Haberstroh Schneider Architekten

The dismantling of all the old additional elements called for a controlled addition of new expansions.

Haus von Arx by Haberstroh Schneider Architekten

These new volumes were clustered at the western side of the plot, touching the old building only in one place.

Haus von Arx by Haberstroh Schneider Architekten

While the old building had been freed from any disturbing elements and thus restored to its classic elegance, the new cubes present a composition of simple and plastically reduced volumes.

Haus von Arx by Haberstroh Schneider Architekten

The cubes, according to their different position, spacing and size, create fascinating passageway- and patio-situations with the old building.

Haus von Arx by Haberstroh Schneider Architekten

To the south-western side of the plot we removed the former winter garden. In its place we constructed a generous, open garden pavilion which works well as mediating element between old building, pool area and the garden.

Ippolito Fleitz Group installs metal trees in natural foods restaurant

Undulating branches emerge from the centre of a dining table at this Swiss natural foods restaurant by Ippolito Fleitz Group (+ slideshow + photographs by Zooey Braun).

Not Guilty restaurant by Ippolito Fleitz Group

The Not Guilty restaurant in Zurich by German studio Ippolito Fleitz Group features a canopy of white lacquered steel pipes that poke up through a canopy of ribbons. “The meandering branches of the trees create a focal point from outside the restaurant, drawing one’s gaze from the street through the elongated floor plan,” the architects told Dezeen.

Diagonally and vertically strung twine in varying thicknesses is installed on the walls above dining tables to the rear of the restaurant.

“The woven pattern on the walls was created from dark and light coloured henna twine, backlit with cove lighting built into the supporting frame,” said the designers.

Vertical strips rise from the back of circular booths and curve at ceiling height to look like oversized birdcages.

Monochrome illustrations feature on the opposite wall in white frames against pink-coloured surfaces.

At the front of the store, drinks and other products are displayed in alcoves. A large extractor fan is encased in glass and positioned in between the salad bar and the dining area.

This is the third branch of the Not Guilty restaurant chain to open in Zurich. The first two were also designed by the Ippolito Fleitz Group.

Here is some more information from the designer:


The Swiss restaurant chain “not guilty” is the embodiment of honest and nutritious foods, imaginatively prepared into many different salads and snacks.

Not Guilty restaurant by Ippolito Fleitz Group_dezeen_18

The downtown Zurich location, opened in 2013, is now the 3rd location of the “not guilty” expansion to have opened.

Not Guilty restaurant by Ippolito Fleitz Group_dezeen_17

In this flagship locale, the philosophy of a “little heaven on Earth” is expressed in the store’s interior, inspiring those within to delight in the harmony of nature.

Not Guilty restaurant by Ippolito Fleitz Group_dezeen_16

The long, open restaurant welcomes its guests with the familiar tones and textures of natural oak wood flooring combined with mixture of delicate white and pastel tones.

Not Guilty restaurant by Ippolito Fleitz Group_dezeen_21

The entrance focal point is the colourful salad bar, and a menu board designed like a kitchen hutch.

Not Guilty restaurant by Ippolito Fleitz Group_dezeen_15

But even from outside, the guests are invited simply to join the other guests at the long, central, high table canopied by the meandering, white lacquered branches of floor to ceiling trees.

Not Guilty restaurant by Ippolito Fleitz Group_dezeen_23

Nearby, several other types of seating are also available – something to everyone’s taste. The dominant materials within the space speak to purity, synonymous with the wholesome standard of the chain.

Playful and unexpected elements, like the taught, twisted canvas ceiling bands, and the cloud and hemp twine wall graphic underline the attention to, and love of detail – a reflection of the passion and honesty of the “not guilty” family.

Jørn Utzon’s unbuilt Schauspielhaus digitally resurrected by Virtual Design Unit

News: Swiss studio Virtual Design Unit has created a computer model of an unbuilt Zurich theatre designed by Jørn Utzon in 1964, to show that the building “could be built now” (+ slideshow + interview).

Schauspielhaus by Jørn Utzon for Zurich virtually constructed in realisticc renders by Virtual Design Unit

“We saw the project that Utzon did in 1964 and we were curious if this project could still be there today, or would be better than all the suggestions that have been made [for the site] in the last 20 years,” said Susanne Fritz of Virtual Design Unit. “It could be built now.”

Utzon, the Danish architect best known for the Sydney Opera House, won a competition 50 years ago to design the Schauspielhaus on the spot next to the Kunsthaus in Zurich, Switzerland, but after a decade of planning the project was abandoned.

Local opposition to David Chipperfield’s proposed extension to the Kunsthaus on the same site prompted Virtual Design Unit, co-founded by architects Fritz and Patrick Schöll, to revisit Utzon’s design in the hope of demonstrating that the building could still be an icon for the city today.

Schauspielhaus by Jørn Utzon for Zurich virtually constructed in realisticc renders by Virtual Design Unit

The images show the building as it would appear today, with a slightly weathered facade as though it had been build ten years ago. Fritz said the images could help show the people of Zurich how the building would fit into the cityscape – something Utzon was unable to do at the time.

“It’s a theory that [Utzon’s] project wasn’t successful because the people of Zurich couldn’t imagine what it would look like,” Fritz told Dezeen. “There was a wooden model built but I think [digital] visualisations make architecture assessable for many people. The visualisation shows, in a photorealistic way, the building in context where it could be.”

Schauspielhaus by Jørn Utzon for Zurich virtually constructed in realisticc renders by Virtual Design Unit

The project is the first known example of an unrealised architectural icon from the past being resurrected in this way. In a recent interview with Dezeen, rendering expert Peter Guthrie said 3D visualising techniques made architecture easier for the public to understand. “It makes un-built architecture more immediate and allows for greater conversation about the built environment,” he says.

Virtual Design Unit’s reconstruction was based on documents from the city’s archives and plans belonging to Utzon’s family. They knew the son of Utzon through a friend and he helped to advise them on details and put them in touch with the project manager who worked on the original design.

“We were detectives putting things together and building this thing in 3D,” said Fritz, who created the 3D model in Cinema 4D and rendered in V-Ray, then the post-production work was done in Photoshop. “We had to have a lot of creativity in the interior; we still don’t know how the interior would look because they didn’t go too much into the detail on the plans.”

The team made decisions about how Utzon may have designed the auditorium based on details of the Sydney Opera House, and chose lighting and fixtures based on knowledge of suppliers who were around at the time.

The most striking feature of Utzon’s design for the Schauspielhaus is the wavy concrete roof. “He was always a fan of these concrete shells and he was always trying to get the climax of the diameter of the concrete,” she said. “His shells were kind of the same concept as in the inside of the Sydney Opera House: they were very good for the acoustics.”

The building was designed to step up gradually from the plaza so the entrance was on the same level as a park on the opposite side. “It’s a very horizontal building but I think this platform is the main attraction of the building – that you were on another level of the city, above the ground and a bit in another world.”

Schauspielhaus by Jørn Utzon for Zurich virtually constructed in realisticc renders by Virtual Design Unit

Virtual Design Unit is now talking to Marianne Panton about creating a “virtual refurbishment” of the famous canteen designed by her late husband Verner Panton for the Hamburg headquarters of the publishers of the Spiegel magazine in 1969. “The difference this time is that we have photo material showing what it actually was, so there’s less interpretation about the furniture they used,” Fritz noted. “There is a desire to revisit this building and this way you could revisit it virtually.”

Schauspielhaus by Jørn Utzon for Zurich virtually constructed in realisticc renders by Virtual Design Unit

Here’s a transcript of the interview with Susanne Fritz:


Rose Etherington: How did the project come about?

Susanne Fritz: In Zurich there is a political discussion about what is going to happen to this place – whether it’s going to be an extension of the Kunsthaus museum – and then we saw the project that Utzon did in 1964 and we were curious if this project could still be there today, or would be better than all the selections that have already been made in the last 20 years.

We had been digging into the city’s archives and we found all these plans for the competition but no detailed drawings. Then, knowing the son of Utzon, we called him to ask if it would be okay to give us more information and plans out of their archives. He did so and put us in contact with the project manager who worked on the competition but lives in Turkey now.

They gave us more detailed information about the building and helped us out. We were detectives putting things together and building this thing in 3D, then we showed them the images and they liked it.

Rose Etherington: How much detail was included in the archive material? Did you have to use some creativity and fill in the blanks?

Susanne Fritz: We had to have a lot of creativity in the interior. We still don’t know how the interior looks because they didn’t go too much into the detail of the plans. Looking at the interior of the Sydney Opera house, we came to some conclusions about how we could have done that. Then let’s say for the lighting, in Scandinavia there weren’t so many lamps available compared to today so it was kind of an interpretation thing but it was signed off by Jørn Utzon’s son.

Rose Etherington: Do you think this building would have been a better building for the site than the one that is being proposed?

Susanne Fritz: Well it would definitely be a very interesting building but the problem is that Utzon didn’t pay a lot of attention to the site and the whole restructuring of the whole area would be necessary and demolition of buildings which are under protection.

So I think the architectural project is great but you also have to pay attention to the people who are quite conservative. They don’t want to demolish buildings which are of heritage or historical value and I think if you are an architect, you have to pay attention to that sensitivity in the project. From only an architectural point of view, I think it would have been a great building in the right position.

Schauspielhaus by Jørn Utzon for Zurich virtually constructed in realisticc renders by Virtual Design Unit

Rose Etherington: Is that why it wasn’t realised at the time? Because it wasn’t right for the site?

Susanne Fritz: It was because they wanted to spend 27 million on the project and then he changed the building so they had to reorganise the traffic. First they tried to put the traffic underground and then through the building, it got a totally different dimension, and suddenly it was more than twice [the budget] and it got really expensive. The demolition of these old buildings was also an issue.

There was this rumour from Sydney. What happened [with the Sydney Opera House] was that Utzon couldn’t finish the project and started changing things. He wrote a letter to the minister and said that he can’t work under these conditions and the minister thought that this was him resigning from the project and obviously quit with Utzon and hired another architect.

All the other architects were against this and voted for Utzon but of course there were also people who thought it was his fault, that he didn’t have the capacities or the experience to do that large building, so there was some stress and some people thought that he couldn’t be trusted.

I think it was a combination of a couple of things [that led to the Zurich project being abandoned] and no one knows for sure. We don’t know what the City Council talked about in their session. They suddenly abandoned the project after seven years of planning.

Rose Etherington: Can we talk about Utzon’s design? What his main idea for the building?

Susanne Fritz: He was always a fan of these concrete shells and in Sydney they thought that it couldn’t be possible to do such a big shell. He is always trying to get the climax of the diameter of the concrete. Concrete shells were his speciality and he applied that [with the Schauspielhaus] again. His shells were kind of the same concept as in the inside of the Sydney Opera House: they were very good for the acoustics. He said that he wanted to transfer the image of the wave to this building.

Schauspielhaus by Jørn Utzon for Zurich virtually constructed in realisticc renders by Virtual Design Unit

Rose Etherington: Are there other features that are distinctive to his work in this building?

Susanne Fritz: The original idea that the Zurich people liked was the main hall was not a hierarchic interior, where you have different levels and then the balconies. He skipped the balconies and ended up with one big floor, and there’s no social distinction between the first and second balcony.

Rose Etherington: What would it have been like for the visitors of the building?

Susanne Fritz: I think for him how you approach a building was very important, so the building kind of slowly rises and steps over the place and there’s a little hill with a park on the other site. So when you go up to the entrance you would have been on the same level as the park opposite. I think it would have been very a very nice view and also you’d be above the ground and a bit in another world. And then you could wonder in this building into the different halls. It’s a very horizontal building but I think this platforms is the main attraction of the building – that you were on another level of the city.

Rose Etherington: It looks like there’s a waterfall coming off the edge of the roof.

Susanne Fritz: Yes that’s an interpretation. We thought that could be nice, but we don’t know if it was planned.

Schauspielhaus by Jørn Utzon for Zurich virtually constructed in realisticc renders by Virtual Design Unit

Rose Etherington: Have you always been a fan of his work or was it this particular project that got you interested?

Susanne Fritz: I really love his work and I really love concrete architecture. I mean Utzon was also a great engineer. Of course he worked with Ove Arup, but all the architects gave up because they couldn’t solve this big shell problem. Because he was always studying bionics, he looked at nature and he took the static rules of nature and translated them into building. He was one of the first architects to do that and that’s really admirable.

Rose Etherington: What capabilities do realist rendering techniques give us now?

Susanne Fritz: The greatest possibility is that you can make these designs accessible to everybody. It’s a theory that [Utzon’s] project wasn’t successful because the people of Zurich couldn’t imagine what it would look like. There was a wooden model built but I think [digital] visualisations make architecture assessable for many people.

Some say that these visualisations don’t leave room for interpretation, which is true. With a sketch you can have much more interpretation and I’m sure if he made detailed imagery it might have had the same effect. But the visualisation shows, in a photorealistic way, the building in context where it could be.

Rose Etherington: Do you think if Utzon had access to these kind of visualisation techniques at the time that the project might have been successful?

Susanne Fritz: I think it could have been a way, because people are open to many kinds of aesthetics and architecture. I think [Switzerland] is a really progressive country in terms of architecture and there could have been more people who supported the project because the people of Zurich have a voice and they will raise it and they will raise issues if they want something or if they don’t want something.

Schauspielhaus by Jørn Utzon for Zurich virtually constructed in realisticc renders by Virtual Design Unit

Rose Etherington: What will you do with the images now?

Susanne Fritz: We are planning an exhibition but we want to wait a bit because we have another project in the pipeline. I met Marianne Panton, the wife of Vernor Panton. The famous Spiegel Canteen [designed by Panton for the Hamburg headquarters of the publishers of the Spiegel magazine in 1969] is not there anymore and there are lots of images for it, but actually the project isn’t documented very well. So we want to get out the plans again and work with Marianne Panton to get books and information. We might also rebuild this building, and the building was once there and it’s not there anymore, so we’re doing a virtual refurbishment. We thought we could do both things and then make an exhibition about both things.

Rose Etherington: Is there anything different about doing a virtual refurbishment rather than a virtual build?

Susanne Fritz: The difference this time is that we have photo material showing what it actually was, so there’s less interpretation about the furniture they used etc. Right after we heard about it, they rebuilt the canteen in an exhibition because the canteen is so famous. That proves that there is a desire to revisit this building and this way you could revisit it virtually.

Rose Etherington: Have you ever recreated a building from the past?

Susanne Fritz: No, the Schauspielhaus by Jørn Utzon is the first. Normally we’re creating architecture which we know is never going to be built, though. There are companies who want to place their product in a context of architecture, so we design the architecture for them virtually and place the product and shoot a photo which they use for marketing purposes. We act as architects, we draw plans, we built it in 3D to be built. We’re working on a catalogue. We would also write the text for it. We’re acting as art director and visualisation and text provider.

Rose Etherington: Did you want to try and make the Schauspielhaus appear as if it was new or as if it had been there since the 1960s?

Susanne Fritz: If you look at the images now it looks like a concrete building after a facade clean. We don’t make it look old or used. The the way [the images] look now is as if it was built 10 years ago, but if it would have been built in the 1960s, it would look different.

We talked about if we wanted to make it look like in the 1960s, rendering cars and people from the 1960s, but we wanted to put the building in today’s context rather than looking at the past because we think there’s a discussion about what to do with this place. There’s different money going into different studies and competitions, so you could pull out a super nice project and it could be built now. I mean they would have to modify it, but yes it could be built now.

Schauspielhaus by Jørn Utzon for Zurich virtually constructed in realisticc renders by Virtual Design Unit

Rose Etherington: Do you think renderings need to look a bit dirty to seem real?

Susanne Fritz: A lot of people do lots of renderings that look sleek and clean. They all look the same because the building standard is similar. You have parquet flooring, furniture that is minimal, Modern architecture with big windows – beautiful architecture -but I think they all look the same. The most difficult thing to do is render old bricks. It’s really hard to make it look real. Or natural textures and surfaces, or even furniture. I love furniture but in all the magazines we see, vintage is mixed with modern furniture and it often makes something special, because there’s some heritage in it. I think that’s the most difficult thing to render.

Rose Etherington: How do you think architectural rendering should change?

Susanne Fritz: The human level in renderings – nowadays they put a ball in the image with shoes lying around, but people have decided now to create blankets. I think there will always be beautiful stills but I think it’s moving more towards moving image and animation. We are close to really super nice animation where rivers flow and people walk around.

I guess that you can walk around interactively in a rendering and thats not possible now, because it has to be rendered in real time and nobody can provide that in the quality that you want. But that’s something I always hear from clients. They want to walk around in the rendering. Not on a path that somebody sets for them but interactively and nobody can do it. They render for hours and hours but if you have a rendering that you can walk around in room, your eyes capture thousands of images in seconds, the designer would have to render all these thousands of images per second when you look at it and there’s no computer that can do it. In ten to 20 years you can look at it in a really photorealistic quality as if you looking at your room now.

Schauspielhaus by Jørn Utzon visualised by Virtual Design Unit

Swiss studio Virtual Design Unit has created realistic renderings of a theatre that was designed for Zurich by Sydney Opera House architect Jørn Utzon in 1964, but never built (+ slideshow + interview).

The Danish architect won a competition 50 years ago to design the Schauspielhaus on the spot next to the Kunsthaus in Zurich, but after a decade of planning the project was abandoned and remains unrealised.

“We saw the project that Utzon did in 1964 and we were curious if this project could still be there today, or would be better than all the suggestions that have been made in the last 20 years,” Susanne Fritz of Virtual Design Unit told Dezeen.

She explained that using hyper-realistic visualisation techniques it’s now possible to create convincing renderings of buildings that were never actually constructed.

“The greatest possibility is that you can make these designs accessible to everybody,” she said. “It’s a theory that [Utzon’s] project wasn’t successful because the people of Zurich couldn’t imagine what it would look like – there was a wooden model built but I think [digital] visualisations make architecture assessable for many people… the visualisation shows, in a photorealistic way, the building in context where it could be.”

Their 3D construction was based on documents from the city’s archives and plans belonging to Utzon’s family. They knew the son of Utzon through a friend and he helped to advise them on details as well as putting them in touch with the project manager who worked on the original design.

The 3D model was created in Cinema 4D and rendered in V-Ray, then the post-production work was done in Photoshop. They chose to show the building in a modern context with a slightly weathered facade, as though it had been build ten years ago. “We talked about whether we wanted to make it look like in the 1960s – rendering cars and people from the 1960s – but we wanted to put the building in today’s context rather than looking at the past because we think there’s a discussion about what to do with this place,” said Fritz.

Having made the detailed 3D model, she believes Utzon’s proposal could still be suitable for construction on the site today. “There’s different money going into different studies and competitions, so you could pull out this super nice project and it could be built now. I mean they would have to modify it, but yes, it could be built now.”

She also thinks that rendered environments need to look a little worn in order to seem credible. “A lot of people do lots of renderings that look sleek and clean. They all look the same because the building standard is similar,” she explained. “The most difficult thing to do is render old bricks. It’s really hard to make it look real. Or natural textures and surfaces, or even [old] furniture.”

While it’s now possible to produce convincing photo-realistic renderings, Fritz thinks the next step is towards realistic animations. “I think there will always be beautiful stills but I think it’s moving more towards moving image and animation,” she told us. “We are close to really super nice animation where rivers flow and people walk around.”

Looking further ahead, she believes that in ten to 20 years it will be possible to create a photo-realistic environment where the user can look around and explore wherever they want. “That’s something I always hear from clients: they want to walk around in the rendering. Not on a path that somebody sets for them, but interactively.”

She explained that this isn’t possible yet due to the current limitations of computing power. “If you have a rendering that you can walk around in, your eyes capture thousands of images in seconds. It has to be rendered in real time and nobody can provide that in the quality that you want.”

The Schauspielhaus by Jørn Utzon is the first project by the studio to create a virtual version of a building that was never constructed, though most of their work involves creating virtual environments that will never be built, to feature in catalogues.

Virtual Design Unit is now talking to Marianne Panton about creating a “virtual refurbishment” of the famous canteen designed by her late husband Verner Panton for the Hamburg headquarters of the publishers of the Spiegel magazine in 1969. “The difference this time is that we have photo material showing what it actually was, so there’s less interpretation about the furniture they used,” Fritz noted. “There is a desire to revisit this building and this way you could revisit it virtually.”

Looking at the interior of the Sydney Opera house, we came to some conclusions about how we could have done that. Then let’s say for the lighting, in Scandinavia there weren’t so many lamps available compared to today so it was kind of an interpretation thing but it was signed off by Jørn Utzon’s son.

Rose Etherington: Do you think this building would have been a better building for the site than the one that is being proposed?

Susanne Fritz: Well it would definitely be a very interesting building but the problem is that Utzon didn’t pay a lot of attention to the site and the whole restructuring of the whole area would be necessary and demolition of buildings which are under protection.

So I think the architectural project is great but you also have to pay attention to the people who are quite conservative. They don’t want to demolish buildings which are of heritage or historical value and I think if you are an architect, you have to pay attention to that sensitivity in the project. From only an architectural point of view, I think it would have been a great building in the right position.

Rose Etherington: Is that why it wasn’t realised at the time? Because it wasn’t right for the site?

Susanne Fritz: It was because they wanted to spend 27 million on the project and then he changed the building so they had to reorganise the traffic. First they tried to put the traffic underground and then through the building, it got a totally different dimension, and suddenly it was more than twice [the budget] and it got really expensive. The demolition of these old buildings was also an issue.

There was this rumour from Sydney. What happened [with the Sydney Opera House] was that Utzon couldn’t finish the project and started changing things. He wrote a letter to the minister and said that he can’t work under these conditions and the minister thought that this was him resigning from the project and obviously quit with Utzon and hired another architect.

All the other architects were against this and voted for Utzon but of course there were also people who thought it was his fault, that he didn’t have the capacities or the experience to do that large building, so there was some stress and some people thought that he couldn’t be trusted.

I think it was a combination of a couple of things [that led to the Zurich project being abandoned] and no one knows for sure. We don’t know what the City Council talked about in their session. They suddenly abandoned the project after seven years of planning.

Rose Etherington: Can we talk about Utzon’s design? What his main idea for the building?

Susanne Fritz: He was always a fan of these concrete shells and in Sydney they thought that it couldn’t be possible to do such a big shell. He is always trying to get the climax of the diameter of the concrete. Concrete shells were his speciality and he applied that [with the Schauspielhaus] again. His shells were kind of the same concept as in the inside of the Sydney Opera House: they were very good for the acoustics. He said that he wanted to transfer the image of the wave to this building.

Rose Etherington: Are there other features that are distinctive to his work in this building?

Susanne Fritz: The original idea that the Zurich people liked was the main hall was not a hierarchic interior, where you have different levels and then the balconies. He skipped the balconies and ended up with one big floor, and there’s no social distinction between the first and second balcony.

Rose Etherington: What would it have been like for the visitors of the building?

Susanne Fritz: I think for him how you approach a building was very important, so the building kind of slowly rises and steps over the place and there’s a little hill with a park on the other site. So when you go up to the entrance you would have been on the same level as the park opposite. I think it would have been very a very nice view and also you’d be above the ground and a bit in another world. And then you could wonder in this building into the different halls. It’s a very horizontal building but I think this platforms is the main attraction of the building – that you were on another level of the city.

Rose Etherington: It looks like there’s a waterfall coming off the edge of the roof.

Susanne Fritz: Yes thats an interpretation. We thought that could be nice, but we don’t know if it was planned.

Rose Etherington: Have you always been a fan of his work or was it this particular project that got you interested?

Susanne Fritz: I really love his work and I really love concrete architecture. I mean Utzon was also a great engineer. Of course he worked with Ove Arup, but all the architects gave up because they couldn’t solve this big shell problem. Because he was always studying bionics, he looked at nature and he took the static rules of nature and translated them into building. He was one of the first architects to do that and that’s really admirable.

Rose Etherington: What capabilities do realist rendering techniques give us now?

Susanne Fritz: The greatest possibility is that you can make these designs accessible to everybody. It’s a theory that [Utzon’s] project wasn’t successful because the people of Zurich couldn’t imagine what it would look like. There was a wooden model built but I think [digital] visualisations make architecture assessable for many people.

Some say that these visualisations don’t leave room for interpretation, which is true. With a sketch you can have much more interpretation and I’m sure if he made detailed imagery it might have had the same effect. But the visualisation shows, in a photorealistic way, the building in context where it could be.

Rose Etherington: Do you think if Utzon had access to these kind of visualisation techniques at the time that the project might have been successful?

Susanne Fritz: I think it could have been a way, because people are open to many kinds of aesthetics and architecture. I think [Switzerland] is a really progressive country in terms of architecture and there could have been more people who supported the project because the people of Zurich have a voice and they will raise it and they will raise issues if they want something or if they don’t want something.

Rose Etherington: What will you do with the images now?

Susanne Fritz: We are planning an exhibition but we want to wait a bit because we have another project in the pipeline. I met Marianne Panton, the wife of Vernor Panton. The famous Spiegel Canteen [designed by Panton for the Hamburg headquarters of the publishers of the Spiegel magazine in 1969] is not there anymore and there are lots of images for it, but actually the project isn’t documented very well. So we want to get out the plans again and work with Marianne Panton to get books and information. We might also rebuilt this building, and the building was once there and it’s not there anymore, so we’re doing a virtual refurbishment. We thought we could do both things and then make an exhibition about both things.

Rose Etherington: Is there anything different about doing a virtual refurbishment rather than a virtual build?

Susanne Fritz: The difference this time is that we have photo material showing what it actually was, so there’s less interpretation about the furniture they used etc. Right after we heard about it, they rebuilt the canteen in an exhibition because the canteen is so famous. That proves that there is a desire to revisit this building and this way you could revisit it virtually.

Rose Etherington: Have you ever recreated a building from the past?

Susanne Fritz: No, the Schauspielhaus by Jørn Utzon is the first. Normally we’re creating architecture which we know is never going to be built, though. There are companies who want to place their product in a context of architecture, so we design the architecture for them virtually and place the product and shoot a photo which they use for marketing purposes. We act as architects, we draw plans, we built it in 3D to be built. We’re working on a catalogue. We would also write the text for it. We’re acting as art director and visualisation and text provider.

Rose Etherington: Did you want to try and make the Schauspielhaus appear as if it was new or as if it had been there since the 1960s?

Susanne Fritz: If you look at the images now it looks like a concrete building after a facade clean. We don’t make it look old or used. The the way [the images] look now is as if it was built 10 years ago, but if it would have been built in the 1960s, it would look different.

We talked about if we wanted to make it look like in the 1960s, rendering cars and people from the 1960s, but we wanted to put the building in today’s context rather than looking at the past because we think there’s a discussion about what to do with this place. There’s different money going into different studies and competitions, so you could pull out a super nice project and it could be built now. I mean they would have to modify it, but yes it could be built now.

Rose Etherington: Do you think renderings need to look a bit dirty to seem real?

Susanne Fritz: A lot of people do lots of renderings that look sleek and clean. They all look the same because the building standard is similar. You have parquet flooring, furniture that is minimal, Modern architecture with big windows – beautiful architecture -but I think they all look the same. The most difficult thing to do is render old bricks. It’s really hard to make it look real. Or natural textures and surfaces, or even furniture. I love furniture but in all the magazines we see, vintage is mixed with modern furniture and it often makes something special, because there’s some heritage in it. I think that’s the most difficult thing to render.

Rose Etherington: How do you think architectural rendering should change?

Susanne Fritz: The human level in renderings – nowadays they put a ball in the image with shoes lying around, but people have decided now to create blankets. I think there will always be beautiful stills but I think it’s moving more towards moving image and animation. We are close to really super nice animation where rivers flow and people walk around.

I guess that you can walk around interactively in a rendering and thats not possible now, because it has to be rendered in real time and nobody can provide that in the quality that you want. But that’s something I always hear from clients. They want to walk around in the rendering. Not on a path that somebody sets for them but interactively and nobody can do it. They render for hours and hours but if you have a rendering that you can walk around in room, your eyes capture thousands of images in seconds, the designer would have to render all these thousands of images per second when you look at it and there’s no computer that can do it. In ten to 20 years you can look at it in a really photorealistic quality as if you looking at your room now.

House renovation in Saignelégier by Dubail Begert Architectes

Artificial grass blankets one wall of this renovated house in Switzerland by local studio Dubail Begert Architectes (+ slideshow).

Architects Sylvain Dubail and David Begert were tasked with improving the thermal efficiency of the two-storey 1970s house in Saignelégier, north-west Switzerland.

After adding extra insulation, they installed a new facade intended to reference the surrounding ground surfaces.

The rear wall is covered with artificial turf to match the garden lawn, while corrugated fibre-cement panels clad three walls and the roof as a nod to the grey tarmac of the road.

The architects compare the appearance to agricultural structures. “The house refuses the romantic and nostalgic ode to the bygone campaign and scoops out its inspirations contrariwise from the contemporary farm sheds,” they said.

Interior spaces are kept simple, with clean white walls and floors, wooden furniture and ceilings, plus a few details picked out in green.

Other projects on Dezeen to feature artificial grass include a cook-for-yourself restaurant in Lithuania and the former home and studio of pop artist Roy Lichtenstein.

Here’s some more text from Dubail Begert Architectes:


Transformation residential house Saignelégier

Located in a residential area, this house built in 1974 is isolated outside to answer contemporary thermal requirements.

House renovation in Saignelégier by Dubail Begert Architectes

The facades plays on the theme of the mimicry with the materials of the floors of the outdoor spaces: place of access in bitumen and grassy garden. The three facades road side and the roof are coated with plates of fibre-cement corrugated anthracites (eternit), the facade garden side is coated with artificial turf.

The surface of outside spaces is extended so at the farthest and tends to remove the home in its stereotypic context of a neighbourhood of houses, delaying so in doubt the icon of sacrosanct single-family home.

House renovation in Saignelégier by Dubail Begert Architectes

In the middle of a quarter of villas of the years 70-80, composed in the majority of houses drawing inspiration from the traditional farm of the Swiss Jura mountains, the house refuses the romantic and nostalgic ode to the bygone campaign and scoops out its inspirations contrariwise from the contemporary farm sheds, to remind of the past close to a residential quarter and ask the question of the rurban sprawl and the maintenance of environmental heritage.

La Fabrique by Bureau A

Swiss architecture studio Bureau A has built a pavilion out of recycled windows on the outskirts of Geneva.

La Fabrique by Bureau A

Named La Fabrique, the structure was inspired by comic actor Buster Keaton’s 1920 short film One Week, where a pair of newlyweds attempt to construct a small house from a kit of parts but are disrupted by disorganised components, causing them to argue.

La Fabrique by Bureau A

“La Fabrique is built with a similar mixture of seriousness and lightness,” said Bureau A co-founder Daniel Zamarbide.

“The lightness comes from the direct relation between thinking and doing,” he adds. “The seriousness relates to the difficulty of producing self-built and affordable space in the western world’s cities and the sadness of the loss of spontaneity in architectural processes.”

The pavilion provides a garden folly for a family, who worked alongside Bureau A to construct it.

An assortment of windows found on demolition sites were mounted to an asymmetric timber frame to create the facade and roof, while the floors and end walls were built from timber boards and chunky chipboard.

Another project featuring recycled windows is Dezeen’s office interior in north London.

Other pavilions completed recently include a temporary library clad in recycled food packaging and an inflatable pavilion with a floating roof. See more pavilions on Dezeen »

Here’s a project description from Bureau A:


La Fabrique

Buster Keaton’s short film One Week describes how a recently married couple installs its kit-house on a small plot of land. The dismountable home conceived to be self-built in seven days only is their wedding gift. Difficulties start when a rival of the couple disorganises the component boxes to trouble the mounting and thus the happiness of the young couple’s first household. This canonical short film, first release of Keaton on his own, has been the catalyst of numerous discourses on art and architecture. Deadpan, shot by Steve Macqueen in 1997, is only one of many art pieces referencing One Week (although Macqueen might refers more directly to Steamboat Bill Junior’s collapsing facade filmed in 1928, 8 years later than One Week).

Keaton’s representation of the self-constructed house can be paralleled with Walker Evans’ photographic documentation conducted just after the Great American Depression of 1929 for the Farm Security Administration. They both show, in drastically different ways, how the American family was occupying the territory in those harsh times. The pride of the poor owners immortalised by Walker Evans could freely be transposed to the 1920’s face of Buster Keaton, the man who never laughed.

La Fabrique is built with a similar mixture of seriousness and lightness. The pavilion made out of recycled windows found on demolition sites is designed and built by BUREAU A and the inhabitants in a couple days. The lightness comes from the direct relation between thinking and doing. Architecture’s usually long and complex process shrink to a point where pleasure and will become real actors of the design. For that matter, the nature of the pavilion resembles the emancipated miniature architecture of the follies of the garden culture. The seriousness relates here to the difficulty of producing self built and affordable space in western world’s cities and the sadness of the loss of spontaneity in architectural processes. Like Buster Keaton’s wedding present, La Fabrique is poetic and playful architecture within a serious context.
