Iredale Pedersen Hook updates a traditional Perth house with a faceted extension

Australian architecture office Iredale Pedersen Hook has renovated a 1930s property in Perth and added an angular rear extension that contrasts with the traditional street-facing facade (+ slideshow).

Architects Adrian Iredale and Caroline Di Costa of Iredale Pedersen Hook own the house and have been gradually conducting renovations over the past four years to adapt it to the changing needs of their young family.

Mindful of preserving the property’s historic aesthetic while updating its functionality, the architects retained the front facade and based the faceted shape of the extension on the multiple sloping surfaces of the original roof.

“Folding forms developed from the existing roof achieve a reinterpretation of the surrounding streetscape and roofscape, binding old and new [as well as] historic and contemporary,” said the architects. “A Jekyll and Hyde quality, the street appearance remains almost untouched; a silent figure, a backdrop, the rear is the extrovert, complex and challenging.”

Casa 31 by Iredale Pedersen Hook and Caroline Di Costa

When viewed from the adjacent street, the house appears to retain the appearance of the Queen Anne Federation-style properties typical in the city’s Vincent district, which feature details reminiscent of the Baroque style of architecture that gained popularity in England during the early eighteenth century.

Casa 31 by Iredale Pedersen Hook and Caroline Di Costa

A key feature of this style is a sheltered verandah next to the entrance, which was popular with the Italian and Greek immigrants who moved to the neighbourhood following the First World War. The architects reintroduced this element to the building to enhance the connection between the house, the garden and the street.

The faceted extension extends upwards and outwards from the existing sloping roof at the rear of the property, which prevents it from being seen from the street.

Folding doors on the ground floor can be pulled back to connect the dining room and kitchen with a terrace that projects into the garden.

Casa 31 by Iredale Pedersen Hook and Caroline Di Costa

Above the terrace, the upper storey leans forward to shield the interior from the low summer sun and to make the most of views across the surrounding rooftops.

Casa 31 by Iredale Pedersen Hook and Caroline Di Costa

The facade of the extension is covered with fabric panels, which allow light to permeate and display shadows from the branches of nearby trees. Some of the panels at eye level can be opened to provide views of the horizon.

Casa 31 by Iredale Pedersen Hook and Caroline Di Costa

A cooling system that drips water down the fabric panels to chill hot air before it reaches the interior was based on the principle of the Coolgardie Safe – a traditional refrigeration technique employed by Western Australian miners to cool food.

Casa 31 by Iredale Pedersen Hook and Caroline Di Costa

The angular interior of the study and living room on the upper floor is entirely clad in plywood panels. The sloping back wall replaces the tiles of the original roof and provides a surface that Iredale and Di Costa’s two-year-old daughter uses as a slide.

Casa 31 by Iredale Pedersen Hook and Caroline Di Costa

As well as the roofline, the architects retained features including the chimney, which has been converted into a water collector, and a 1950s sliding door with an amber glass panel at the top of the stairs.

Casa 31 by Iredale Pedersen Hook and Caroline Di Costa

A multipurpose pavilion constructed in the garden features a pyramidal polycarbonate roof, culminating in a transparent panel that allows daylight to reach the interior and provides views of the sky.

CASA31_4 Room House

Conceptual Framework

CASA31_4 Room House re-interprets the role of memory, tradition and social and cultural value in a rich spatial experience that is simultaneous familiar yet unfamiliar. Our architecture preserves and reinterprets the past. History is layered but never erased. Fragments of the past continually remind us that we are only another layer in the rich and unfolding history of this place.

All spaces contain elements of the past, often manifest as objects of intrigue, the sloping floor (the former roof), the barge scrolls on the front fence, the roof tiles creating a musical score along the boundary, the chimney as water collector and the up-cycling of former building elements as decks, gates, architraves and furniture.

Casa 31 by Iredale Pedersen Hook and Caroline Di Costa

A front deck engages with the street, re-introducing the role and value of the front garden as social setting and meeting place, a past tradition by the immigrant Italians and Greeks that has almost disappeared in societies obsession with privacy and security.

Over the last 3 years we have explored our 1936 Queen Anne Mount Hawthorn Federation house scraping, layering, and peeling with 4 primary spatial ideas; the room to the interior, the room to the garden, the room to the horizon, the room to the sky.

Casa 31 by Iredale Pedersen Hook and Caroline Di Costa

The room to the interior explores what existed, years of layering, the art of construction, knowing what to keep, what to reveal and what to remove, knowledge gained from 13 years indulging in the past. Rooms become the embodiment of a city, a microcosm of the qualities that make a great city. The room to the garden focuses attention to the exterior at ground level, it is purposely heavy and grounded engaging with the earth, the section expands to the exterior, a series of folding screens layer the engagement.

A space of deep sensory delight, an architectural palette cleanser, transitions the ground and upper level, the eyes and nose are overpowered by the burnt and waxed plywood walls and the amber light cast by Nan’s 1950’s sliding door.

Casa 31 by Iredale Pedersen Hook and Caroline Di Costa

The room to the horizon filters the suburban roof tops, the screen abstracts the exterior world, the interior is one folded space formed through a play on the one point perspective that intensifies the horizon. Openable screens create a direct view framing the horizon, releasing the interior volume. The space is cooled with an interpretation of the old Coolgardie safe, water is dripped down the fabric cooling the outside air. The newly restored, 1956 Iwan Iwanoff Guthrie residence cabinet finds a new home after 15 years of storage in numerous architect’s garages. The roughly painted ‘I love Linda’ remains on the chimney, a rear window frames the distant Saint Mary’s Church.

The room to the sky creates a vertical spatial experience, a halo of love poems embraces us (former wedding installation) and at night a cross of light abstracted by polycarbonate awakens but unlike St Mary’s Church our little spire opens up to the heavens.

Contribution to lives of inhabitants

After 4 years of renovating it is now time to enjoy the richness and intensity of experience that this renovation has created. Every day is a different experience, one that is tender, unexpected, personal and embedded with history. The design enables our children and us to grow and evolve in a sequence of spaces that encourage engagement with each other and the dwelling and offers new ways of understanding and exploring family relationships and an understanding of space. Our house is simultaneous a memorial, playground, place of celebration, stage set, place of community interaction and most importantly ‘home’.

Casa 31 by Iredale Pedersen Hook and Caroline Di Costa

Program Resolution

The design exploits all areas of the site with an inherent flexibility for not only day to day use but the long term capacity to adapt to evolving and changing requirements as the family grows and ages.

It re-engages with the street and community allowing our children to play in safe environment connected to the street and house. Spaces are specific and flexible, while offering sufficient capacity for personal interpretation and use.

Sustainable Architecture Category

This project includes both a macro and micro approach to sustainability. It also extends the meaning of sustainability beyond environmental to include contextual, social, cultural and economic concerns.

This house will be a case example for the City of Vincent demonstrating the importance of preserving the 1935 Queen Anne Federation home with the capacity to embrace contemporary expectations of living, without comprising the street context or privacy of adjoining properties. The neighbouring house completes the street sequence of ‘twins’ and twins should never be separated.

The removal of material from site is minimised, an attitude of ‘upgrading’ ensures that materials once concealed for structural purposes are now used for furniture, decks, doorframes and architraves.

The upper and lower level spaces are protected from the low, intense summer sun with timber framed fixed and operable screens, the upper level is cooled with a manually operated reticulation system that drip feeds water on to the fabric, hot moving air is rapidly chilled, this is Perth’s largest ‘Coolgardie Safe’, a 19th century low-tech refrigeration system used by the Coolgardie WA gold miners to cool edible goods. Windows are strategically located to maximise cross ventilation or for winter heat gain (north facing highlight window with a deep reveal for shading).

All interior spaces preserve elements of the past, history is layered but never erased. Low energy light fittings, recycled light fittings, low water use and storage, pv cells and solar hot water systems all form part of the sustainable equation but is the focus.

Economy is achieved through re-cycling, restoring, re-interpreting building materials and historic traditions and minimising waste. This project represents a holistic approach to design and dwelling, where memories are preserved, carbon footprint minimised and the concerns of the broader community celebrated.

Context

Folding forms developed from the existing roof achieve a re-interpretation of the surrounding streetscape and roof-scape, binding old and new/ historic and contemporary. A Jekyll and Hyde quality, the street appearance remains almost untouched, a silent figure, a backdrop, the rear is the extrovert, complex and challenging.

A front deck engages with the street, re-introducing the value of the front garden as social setting, a past tradition by the immigrant Italians and Greeks. A mosaic tiled seat offers a place to rest for neighbours. All exterior spaces contain elements of the past, often manifest as objects of intrigue.

Integration of Allied Disciplines

As architect owners we were keen to maintain an open line of discussion that enabled details to be developed and refined as the project evolved. This often involved the capacity to re-use building waste. Our structural engineer and builder eagerly entered in to this arrangement in particular the role of the builder extended beyond the traditional role.

Nannup Holiday House by Iredale Pedersen Hook rises above the Australian bush on stilts

This zigzagging house in Australia by Iredale Pedersen Hook is raised above the ground on stilts to minimise its impact on the native landscape and wildlife (+ slideshow).

Nannup Holiday House by Iredale Pedersen Hook

The holiday home was designed by Australian studio Iredale Pedersen Hook for a site near the town of Nannup. Situated between a forest and a flood plain, the area provides a habitat for local fauna including emus, kangaroos and snakes.

Nannup Holiday House by Iredale Pedersen Hook

The house was given a cranked layout to create different experiences along its length. It was also lifted off the ground to enhance views and reduce disruption to the site.

Nannup Holiday House by Iredale Pedersen Hook

“This is a holiday house, a place of temporary inhabitation that offers a variety of experiences and relationship to the native landscape,” said the architect. “Spaces are strung in a line, an open-ended line that allows one to enter, exist and then leave and continue.”

Nannup Holiday House by Iredale Pedersen Hook

The kinked plan optimises different views of the forest on one side and the horizon on the other. It accommodates outdoor living areas, including an enclosed balcony at the rear of the property and a pointed terrace that projects towards the flood plain.

Nannup Holiday House by Iredale Pedersen Hook

Windows on the angled facades alternate between vertical apertures that make the most of the view towards the nearby trees and longer openings overlooking the plain.

Nannup Holiday House by Iredale Pedersen Hook

The use of the stilts and their diagonal cross-braces references the fallen trees that are a common feature around the forest edge, while the material palette used for the exterior references its natural setting.

Nannup Holiday House by Iredale Pedersen Hook

“Materials were carefully selected to dialogue with the context,” the architects explained. “Dark Colorbond steel, rusting steel and recycled jarrah [wood] contributes to the notion of the building as ‘shadow’.”

Nannup Holiday House by Iredale Pedersen Hook

Long steel grate ramps lead to an entrance at one end of the house and a balcony at the other, continuing past the master bedroom and main living areas to the sheltered terrace.

Nannup Holiday House by Iredale Pedersen Hook

The main entrance opens into a dark corridor that meanders past bedrooms, a laundry and a study, before reaching the two terraces on either side of the bright, open-plan living and dining room.

Nannup Holiday House by Iredale Pedersen Hook

The architects said they wanted to enhance the experience of moving between interior and exterior spaces by emulating the experience of “wandering through a forest in and out of darkness and openness.”

Nannup Holiday House by Iredale Pedersen Hook

Richly textured, dark jarrah wood used on the floor of the corridor contrasts with the bright living spaces, while carefully chosen colours and textures were introduced throughout the interior to evoke the natural surroundings.

Nannup Holiday House by Iredale Pedersen Hook

Treated plantation pine was used for 90 per cent of the building’s framework and recycled local timber features on the outdoor decks as well as internal flooring and storage.

Nannup Holiday House by Iredale Pedersen Hook

Photovoltaic panels on the roof supply the home’s power and a solar-powered system heats its water, which includes rainwater captured from the roof.

Here’s a project description from Iredale Pedersen Hook:


Nannup Holiday House

The Nannup Holiday house forms part of a wandering path through the landscape from Perth to Nannup. This path dialogues with the landscape of intense forest, meandering river and rolling hills, each experience is carefully choreographed to enrich the occupancy of the house. A Jeykll and Hyde experience of the landscape is carefully controlled through oscillating vertical (forest) and horizontal (horizon) openings and the contrast of grounded and floating experiences. While the exterior dialogues with the numerous fallen trees, the interior is revealed through a sequence of ‘growth rings’ coded and extruded in relation to the building program.

Nannup Holiday House by Iredale Pedersen Hook

Program Resolution

This is a holiday house, a place of temporary inhabitation that offers a variety of experiences and relationship to the native landscape. Spaces are strung in a line, an open-ended line that allows one to enter, exist and then leave and continue. The house is part of a broader and longer experience that constitutes the experience of being on ‘holiday’, the travel to and from the site and the experience of visiting local towns and tourist attractions are then contemplated and celebrated in the context of this residence. Spaces are organised to provide a sense of seclusion and retreat, guests view the forest from a distance through vertical windows, the boys view the horizon and rolling hills through shared horizontal openings and the parents almost touch the natural landscape. These areas are collected by a dark, twisting and cranking space clad in recycled jarrah that oscillates between interior and exterior creating a sense of ambiguity and wondering through a forest in and out of darkness and openness. Outlook from this space is carefully controlled to provide detailed relief, openings also align to view through interior to exterior to interior and back to exterior.

Nannup Holiday House by Iredale Pedersen Hook

Built form context relationship

The building hovers above the native landscape minimising disturbance, it is a shadow to the immense forest, cranking in plan and undulating in section. The plan twists in relationship to program requirements and variety of views. The section undulates in direct dialogue to the backdrop forest enriching the spatial experience with variety and complexity; spatial proportion varies between rooms capturing the verticality of the forest and the horizontality of the horizon.

Nannup Holiday House by Iredale Pedersen Hook

It sits between the edge of the forest and the edge of the flood plain, the space between fire and flood, a fragile zone of existence. The ground level is dominated by roaming wild pigs (the size of humans), tiger snakes, dugites and other less threatening native fauna including emus and kangaroos. The elevated house with access via the steel grate ramps creates a safe retreat to observe nature.

Nannup Holiday House by Iredale Pedersen Hook

Materials were carefully selected to dialogue with the context, dark Colorbond steel, rusting steel and recycled Jarrah contributes to the notion of the building as ‘shadow’. This concept continues internally, the main passage being dark and an extension of the exterior (recycled Jarrah) and primary living spaces being lighter and more connected to the exterior (recycled WA Blackbutt). Small fragments of intense colour capture the colours of the forest undergrowth.

Nannup Holiday House by Iredale Pedersen Hook

Integration of Allied Disciplines

The core building team camped on site during construction; it became an obsession, highly crafted and full of pride. Our structural engineer also travelled regularly to site while visiting his own holiday farm in the vicinity. His knowledge of local conditions and contractors was highly valued. The project enjoyed a high level of respect and collaboration between all teams; this is reflected in the end result.

Nannup Holiday House by Iredale Pedersen Hook

Sustainability

This project offers a holistic approach to environmental sustainability commencing with design and placement of access paths. The vehicle access path is placed along the site edge an area that requires annual clearing for the firebreak. This enables us to minimise the clearing of land. The materials required to build the access path were quarried from the site (gravel and clean yellow sand). These areas were immediately rehabilitated with plant species already existing on the site.

Nannup Holiday House by Iredale Pedersen Hook

The house was sited and designed to minimise clearing of bush and removal of trees. The area under the house is then free for re-introducing local species and will be fed by the grey water recycling.

Nannup Holiday House by Iredale Pedersen Hook

Materials were selected based on a life cycle analysis of embodied energy, Colorbond cladding provides a durable exterior core and inhabited areas include recycled Jarrah and recycled WA Blackbutt. Timber off cuts was re-used for storeroom linings.

Nannup Holiday House by Iredale Pedersen Hook

The building structure is 90% treated plantation pine and most furniture constructed from hoop pine plantation plywood. The structure was mostly pre-fabricated to minimise building waste.

The long roof form increases the capacity to capture rainwater, this is re-used in the house. Grey Water is recycled for garden watering under the house. Water is heated from a solar hot water system with back up instantaneous gas hot water systems located close to areas of water use to minimise water waste. Water consumption is reduces with rated fixtures and fittings.

Photo Voltaic cells balanced over the year easily cover consumption requirements. Power consumption is minimised through energy efficient equipment, use of LED and Compact Fluorescent globes and feature wall mounted light fittings manufactured from plantation plywood.

Florida Beach House by Iredale Pedersen Hook

Florida Beach House by Iredale Pedersen Hook

This roof of this sea-facing holiday house in Perth jolts up and down to create four irregular gables.

Florida Beach House by Iredale Pedersen Hook

Recently completed by Australian architects Iredale Pedersen Hook, the single-storey house is externally clad in sheets of fibre-cement.

Florida Beach House by Iredale Pedersen Hook

Terraces on the north, south and west elevations provide residents with at least one outdoor area sheltered from the winds at any time of year.

Florida Beach House by Iredale Pedersen Hook

Iredale Pedersen Hook previously designed a house extension with folding surfaces of corrugated metal and glass – see our earlier story here.

Here are some more details from Iredale Pedersen Hook:


Houses

Inhabiting two platforms- one flat and one undulating.

Located at Florida Beach Western Australia, this design emphasises and focuses on the immense Indian Ocean. All space is aligned and extruded through a strict dialogue of plan and section revealing the intensity and variety of this great ocean.

Florida Beach House by Iredale Pedersen Hook

This is a modern day holiday house only one hour from the capital of Western Australia and surrounded by the sprawling Perth suburbia. We are interested in the past and rapidly disappearing holiday homes that once dominated the nearby landscape, houses that embodied the weekender experience designed with restraint, economy and robustness.

Florida Beach House by Iredale Pedersen Hook

This house captures these dying qualities while screening the occupants from the emerging suburban houses and protecting them from the strong winds and storms. A deck is created on each of the cardinal points allowing the occupants to live externally any time of the year.

Florida Beach House by Iredale Pedersen Hook

Our reference point for the design was found in a sketch by the great Danish architect Jorn Utzon, an image of people congregating on the beach under the dense, stormy Copenhagen sky. Uzton translated this in to the section of a church creating a mystical interior; we translated this in to the section of a holiday house that intensifies the experience of the ocean.

Florida Beach House by Iredale Pedersen Hook

The section undulates in relationship to the plan form; each space includes an undulation that is eventually revealed at the beach side as a series of undulations connecting the living, dining and kitchen spaces to the dynamic ocean environment. The section extrudes from the beach end to the street side, those spaces that do not contain a direct view to the ocean maintain the memory of the ocean view through the continuing section.

Florida Beach House by Iredale Pedersen Hook

External cladding is a strictly controlled ribbon of uncut compressed fibre cement sheeting and rough sawn plywood panels, the plywood inhabit the deck spaces and the CFC provides a durable exterior to storm exposed areas. This material restraint references the past holiday homes. While the exterior is tactile and articulated the interior is smooth and sculptured with subtle variations of white paint colour and gloss levels differentiating interior elements and reflecting the exterior.

Florida Beach House by Iredale Pedersen Hook

A continuous band of high performance glass articulates the wall cladding from the roof, the roof overhang is carefully sized to exclude summer sun and admit low-level winter sun. The stretched western overhang excludes the low level sun allowing the occupants to engage in comfort with the setting sun.

Florida Beach House by Iredale Pedersen Hook

The house appears to gently hover above the ground, a recessed concrete platform creates this illusion, the platform connects this house to the remaining holiday houses and the Dawesville Cut bridge, this is first platform that one passes and signifies the beginning of the holiday experience.

Florida Beach House by Iredale Pedersen Hook

Constructed almost entirely of plantation pine timber, prefabricated and transported to Florida, the raw structure appeared like the carcass of a great whale. The use of steel is minimised to a few select areas where thin columns support the dense undulating roof creating tension in the context of the ocean view.

Florida Beach House by Iredale Pedersen Hook

The hovering platform is finished with recycled Jarrah and continues between the interiors and exterior as one large plane, the holiday experience unfolds on this platform. Finished internally with Whittle Wax and externally with Sikkens oil, this platform will slowly reveal the marks of the beach and holiday lifestyle.

Florida Beach House by Iredale Pedersen Hook

A native landscape garden surrounds this platform, carefully screening the surrounding suburban houses and providing an additional filter to the Western sun and Indian Ocean. The sound of the sea breeze transforms into an eerie whistle as it passes through the Casuarinas (Weeping Beach Sheoaks) reinforcing the complex, intense and delightful relationship to this environment creating a very West Australian experience.
