Reorganization of Pombal Castle’s Hill. Pathways and Facilities
Comoco Arquitectos Luís Miguel Correia, Nelson Mota, Susana Constantino

Previous State

Throughout the last decades, Pombal Castle and its surrounding area have been doomed to seclusion from the core of the city at its feet.

Pombal Castle Hill by Comoco

For the ordinary city user, the Castle was only a background for the everyday, a mere identity reference that resonated with the history of the city more than with an actual experience of it. “Rua do Castelo”, a street defining the South and West perimeter where the hill meets the city, embodied the boundary that defined those two realms.

Pombal Castle Hill by Comoco

From that street, some connections with the walled precinct were possible. They were, however, just a vague memory of previous uses, and their conservation decayed progressively, hampering public use.

Pombal Castle Hill by Comoco

The area’s vegetation – nowadays uncritically cherished by the population – is, paradoxically, the result of the abandon to witch this area was devoted throughout most of the 20th century.

Pombal Castle Hill by Comoco

Aim of the Intervention

The project for the reorganization of Pombal Castle’s hill was launched by the city’s municipality with the goal of promoting the re-centralization of that area. The basic brief of the commission encouraged a design that would help fostering the use of that historic area by both residents and tourists.

Pombal Castle Hill by Comoco

A more elaborated programme was developed collaboratively by municipality’s politicians and technicians, together with the design team and enriched by the feedback delivered by the population at the proposal’s preliminary stage.

Pombal Castle Hill by Comoco

The basic premise was that the project should improve the connections between the urban areas at the bottom of the hill, the hill itself and the walled precinct.

Pombal Castle Hill by Comoco

The articulation with the Castle, the hallmark of the city, should be tackled in order to preserve its importance for the population’s shared identity.

Pombal Castle Hill by Comoco

To increase the area’s attractiveness some facilities should be created to answer needs such as car parking, comfortable and safe pathways, resting and contemplation areas and a cafeteria. Archaeological and preservation works should also be central to bring about and highlight the area’s history.

Pombal Castle Hill by Comoco

Description of the Intervention

The basic character of the intervention is an attempt to deliver an approach were the new designed elements should be clearly defined against the background of both the natural and the built pre-existing elements, without challenging the latters’ character, tough. The project defined three areas, each of which with a different approach.

Pombal Castle Hill by Comoco

In the first area, the south and west slopes of the hill, the approach was focused in the idea of flow. This idea was thus developed creating and highlighting connections between the urban areas at the bottom of the Castle’s hill, pathways along the slopes and gazebos to provide shelter and foster diverse experiences in the contact with the landscape. The materials used were prominently plastered walls, stone and grit pavements, and wooden structures.

Pombal Castle Hill by Comoco

In the second area, in the surroundings of the cemetery, the approach was concerned with the idea of a topographical design of the infrastructure. Both the parking area and the adjacent facilities were designed as topographical elements, concrete walls supporting the transition between sharp differences of levels.

Pombal Castle Hill by Comoco

Finally, the third area, surrounding the walled precinct, aims to enhance the Castle as the main built element of the area. The west access to the Castle was redesigned, including the platform at its bottom.

Pombal Castle Hill by Comoco

The surrounding area of Santa Maria’s Church was also redesigned to provide a public space that could foster its appropriation as a privileged stage for performances and other cultural activities. The material that is thoroughly used in this area is limestone, the same used in the main landmarks, the Castle and the Church’s ruins.

Pombal Castle Hill by Comoco

To work as a connector between these areas, a cafeteria was designed, proving thus an additional element to attract visitors to the area. To highlight its singular role in the overall intervention, the cafeteria was built using a metallic structure and finished with corten steel panels both on its façades and roofs.

Pombal Castle Hill by Comoco

It embodies, thus, the design’s strategy of affirming the new against the pre-existing preserving, however, the identity of the place. With this project we aimed at creating a delicate balance between nature and artefact.

Genesis by David Adjaye

Visitors to this year’s Design Miami/ fair could climb into the hollow belly of a wooden pavilion by architect David Adjaye.

Genesis by David Adjaye

Adjaye was commissioned to create the installation after being named Designer of the Year by the festival back in September.

Genesis by David Adjaye

The temporary triangular structure was located at the fair’s entrance and comprised a framework of timber blocks slotted together.

Genesis by David Adjaye

The central hollow punctured the pavilion on every side to create oval openings framing views of the surroundings and sky.

Genesis by David Adjaye

A secondary timber framework also slotted inside the structure to form a bench.

Genesis by David Adjaye

Previous pavilions have been completed by designers including Zaha Hadid, Marc Newson, Maarten Baas and Konstantin Grcic, whose network of hammocks you can see in our story from last year’s festival.

Genesis by David Adjaye

Here’s some more text from Adjaye Associates:


Genesis Pavilion
Design Miami/ Commission, 2011

Designed to provide visitors with an immersive experience, Genesis is a complete environment, which integrates enclosure, aperture, views, respite, meditation and community.

Genesis by David Adjaye

Like a giant piece of architectural furniture, the Design Miami/commission has enabled Adjaye to combine structure, seating, window and doors into a single gesture for the first time.

Genesis by David Adjaye

The pavilion is a triangular prism measuring 10m x 10m x 10m x 3.6m, located at the entrance to the fair. It leads visitors to the courtyard space upon arrival, ushering people inside.

Genesis by David Adjaye

It is also the point of departure, and is a final gathering space as visitors leave the fair, with its curved window offering strategic views of the galleries.

Genesis by David Adjaye

Comprising a series of timber frames that form the roof, flooring and walls, these elements work together and through compression, provide the overall structure.

Genesis by David Adjaye

The internal space is formed by carving out an oversized ovoid shape from the centre.

Genesis by David Adjaye

This distorted shape is set at an angle and abuts the perimeter to form the exit, entrance and window.

Genesis by David Adjaye

The seating is established by a secondary subtraction from the interior – which repeats the distorted ovoid, creating a platform along the cut-away timber frames.

Genesis by David Adjaye

While compressed and joined together with additional filler pieces, the timber frames are not completely fused.

Genesis by David Adjaye

This allows light to filter inside from the exterior and roof, providing a dynamic filigree of light and shadow.

Genesis by David Adjaye

Light is further brought inside via an opening in the roof, which acts as a dramatic light well.

Here’s some more information from the designer:


The AV Custerson Award was given annually to a member of the Architectural Association community to fund a project promoting the use of timber at Hooke Park. 2007 recipient Jesse Randzio, 3rd Year, organized a month long summer workshop to build a Separate Place, a hanging retreat in the forest.

A Separate Place by Jesse Randzio and Architectural Association students

The project was exhibited at the Architectural Association, London, in 2008.

A Separate Place by Jesse Randzio and Architectural Association students

A Separate Place is a red cedar sitting room for just a few people. There is no building footprint, only shadow, and so minimal site impact. It is tailored specifically to its location but adaptable to any. The door is high and very small, but once inside it’s a fine safe place; there’s a warm fire burning and tea in the kettle.

A Separate Place by Jesse Randzio and Architectural Association students

Jesse designed and built the 4½ square meter floating capsule with the help of a dozen students from throughout the AA. The group visited local industries in Lyme Regis and in Bridport to learn boat building and rigging techniques.

A Separate Place by Jesse Randzio and Architectural Association students

The pod is built of western red cedar in the style of a clinker boat, with copper rivets and trim, and a steel chimney and stove. The timber was felled in the Hooke Park forest, and other materials were supplied locally.

A Separate Place by Jesse Randzio and Architectural Association students

We suggest a future of AV Custerson Award projects that are continuously under examination. Every five years, matching the cyclical forest management plan, a project should be reevaluated and steps should be taken to address the relevance of each project and its relationship to other Hooke Park programs.

A Separate Place by Jesse Randzio and Architectural Association students

In this way, we can ensure that Hooke Park remains an active, vibrant, and productive facility. A Separate Place is coming into its fifth year and is due for reconsideration.

Here’s some further explanation from Stan Allen Architects:


Taichung Infobox

In 2009, Stan Allen Architect completed the master-plan for Taichung Gateway Park, a 240 hectare mixed use quarter to be built on the site of the former Municipal Airport in Taichung, Taiwan.

Taichung Infobox by Stan Allen

The urban design proposal includes a long-term strategy to “grow” the site over time, with civic buildings, infrastructure and residential neighborhoods to be built around a large central park space.

Taichung Infobox by Stan Allen

In order to raise awareness of the Taichung Gateway project, and to bring the public onto this spectacular site, SAA proposed the immediate construction of the InfoBox, a temporary exhibition pavilion to display the site and the project. Throughout the life of the structure, drawings, models and computer animations will be displayed within, while an elevated overlook terrace gives the public a ringside seat to observe the process of construction.

Responding to the need for fast implementation and making the most of a limited budget, the InfoBox re-purposes the ubiquitous bamboo scaffolding technology seen all over Asia. The bamboo structure is not only quick and inexpensive, it is a locally available green technology: all materials will be recycled at the end of the pavilion’s lifespan.

The dense weave of the bamboo creates optical effects which will contribute to the iconic presence of the InfoBox. The systems are flexible and adaptive, both during construction and over the life of the project.

Rollercoaster by Interval Architects

Chinese studio Interval Architects have completed a pavilion that snakes around a school square in Beijing like the tracks of a roller coaster.

Rollercoaster by Interval Architects

The continuous timber belt folds up and down from the ground to create louvred walls and a roof, which are supported by a series of metal columns.

Rollercoaster by Interval Architects

Where the chunky edges of the structure meet the ground they create benches and surround new patches of grass.

Rollercoaster by Interval Architects

As well as providing a seating area for students, the pavilion can also be used as an outdoor exhibition area.

The following text is from Interval Architects:


Rollercoaster

Situated in a tranquil environment of one of the best vocational schools in Beijing, the project aims at providing an iconic image to the institution as well as redefining the use of an existing public space on the central square of the campus.

Rollercoaster by Interval Architects

Initially, the client wanted to put on the square a themed sculpture with a monumental effect and scale. A huge pedestal was even already built for the sculpture to put on. However the obvious problem of the square is actually a severe lack of effective public space that would allow students to gather and communicate. What the school really needs is not a monument in the center of the campus, but a humanistic and functional gathering space for students and an event space for school activities.

Rollercoaster by Interval Architects

Therefore, with the intention to create an efficient public space, we proposed a continuous self-folding belt structure that resembles the image of a “roller coaster”. The structure folds three-dimensionally to create a series of spaces such as open gardens, shaded pavilions and exhibition corridors. The entire belt bends around and in-between the existing trees on the site so they are well-preserved and maximally utilized for shading.

Rollercoaster by Interval Architects

The rollercoaster-like structure presents a highly recognizable identity to the school as well as a fun image that was widely welcomed by the students.

Here’s a bit more text from Snøhetta:


Norwegian Wild Reindeer Centre Pavilion

The Norwegian Wild Reindeer Centre Pavilion is located at Hjerkinn on the outskirts of Dovrefjell National Park, overlooking the Snøhetta mountain massif.

The 90m2 building is open to the public and serves as an observation pavilion for the Wild Reindeer Foundation educational programmes. A 1,5km nature path brings visitors to this spectacular site, 1200 meters above sea level.

Norwegian Wild Reindeer Centre Pavilion by Snøhetta

Background

Dovrefjell is a mountain range that forms a barrier between the northern and southern parts of Norway. It is home to Europe’s last wild reindeer herds and is the natural habitat for many rare plants and animals. A long history filled with travellers, hunting traditions, mining, and military activities has left its mark on this land. In addition to the natural and cultural landscape, the Dovre mountains also holds significant importance in the Norwegian consciousness. National legends, myths, poetry (Ibsen) and music (Grieg) celebrate the mystic and eternal qualities of this powerful place. The founding fathers of the Norwegian constitution are ”agreed and faithful, until the fall of Dovre!”

Norwegian Wild Reindeer Centre Pavilion by Snøhetta

Architectural idea

This unique natural, cultural and mythical landscape has formed the basis of the architectural idea. The building design is based on a rigid outer shell and an organic inner core. The south facing exterior wall and the interior create a protected and warm gathering place, while still preserving the visitor’s view of the spectacular panorama.

Considerable emphasis is put on the quality and durability of the materials to withstand the harsh climate. The rectangular frame is made in raw steel resembling the iron found in the local bedrock. The simple form and use of natural materials reference local building traditions. However, advanced technologies have been utilized both in the design and the fabrication process. Using digital 3D-models to drive the milling machines, Norwegian shipbuilders in Hardangerfjord created the organic shape from 10 inch square pine timber beams. The wood was then assembled in a traditional way using only wood pegs as fasteners. The exterior wall has been treated with pine tar while the interior wood has been oiled.

The pavilion is a robust yet nuanced building that gives visitors an opportunity to reflect and contemplate this vast and rich landscape.

Here’s a more technical description from the researchers:


ICD/ITKE RESEARCH PAVILION 2011

In summer 2011 the Institute for Computational Design (ICD) and the Institute of Building Structures and Structural Design (ITKE), together with students at the University of Stuttgart have realized a temporary, bionic research pavilion made of wood at the intersection of teaching and research. The project explores the architectural transfer of biological principles of the sea urchin’s plate skeleton morphology by means of novel computer-based design and simulation methods, along with computer-controlled manufacturing methods for its building implementation. A particular innovation consists in the possibility of effectively extending the recognized bionic principles and related performance to a range of different geometries through computational processes, which is demonstrated by the fact that the complex morphology of the pavilion could be built exclusively with extremely thin sheets of plywood (6.5 mm).

ICD ITKE Research Pavilion at the University of Stuttgart

BIOLOGICAL SYSTEM

The project aims at integrating the performative capacity of biological structures into architectural design and at testing the resulting spatial and structural material-systems in full scale. The focus was set on the development of a modular system which allows a high degree of adaptability and performance due to the geometric differentiation of its plate components and robotically fabricated finger joints. During the analysis of different biological structures, the plate skeleton morphology of the sand dollar, a sub-species of the sea urchin (Echinoidea), became of particular interest and subsequently provided the basic principles of the bionic structure that was realized.

ICD ITKE Research Pavilion at the University of Stuttgart

The skeletal shell of the sand dollar is a modular system of polygonal plates, which are linked together at the edges by finger-like calcite protrusions. High load bearing capacity is achieved by the particular geometric arrangement of the plates and their joining system. Therefore, the sand dollar serves as a most fitting model for shells made of prefabricated elements. Similarly, the traditional finger-joints typically used in carpentry as connection elements, can be seen as the technical equivalent of the sand dollar’s calcite protrusions.

ICD ITKE Research Pavilion at the University of Stuttgart

MORPHOLOGY TRANSFER

Following the analysis of the sand dollar, the morphology of its plate structure was integrated in the design of a pavilion. Three plate edges always meet together at just one point, a principle which enables the transmission of normal and shear forces but no bending moments between the joints, thus resulting in a bending bearing but yet deformable structure.

ICD ITKE Research Pavilion at the University of Stuttgart

Unlike traditional lightweight construction, which can only be applied to load optimized shapes, this new design principle can be applied to a wide range of custom geometry. The high lightweight potential of this approach is evident as the pavilion that could be built out of 6.5 mm thin sheets of plywood only, despite its considerable size. Therefore it even needed anchoring to the ground to resist wind suction loads.

ICD ITKE Research Pavilion at the University of Stuttgart

Besides these constructional and organizational principles, other fundamental properties of biological structures are applied in the computational design process of the project:

Heterogeneity: The cell sizes are not constant, but adapt to local curvature and discontinuities. In the areas of small curvature the central cells are more than two meters tall, while at the edge they only reach half a meter.

Anisotropy: The pavilion is a directional structure. The cells stretch and orient themselves according to mechanical stresses.

Hierarchy: The pavilion is organized as a two-level hierarchical structure. On the first level, the finger joints of the plywood sheets are glued together to form a cell. On the second hierarchical level, a simple screw connection joins the cells together, allowing the assembling and disassembling of the pavilion. Within each hierarchical level only three plates – respectively three edges – meet exclusively at one point, therefore assuring bendable edges for both levels.

ICD ITKE Research Pavilion at the University of Stuttgart

COMPUTATIONAL DESIGN AND ROBOTIC PRODUCTION

A requirement for the design, development and realization of the complex morphology of the pavilion is a closed, digital information loop between the project’s model, finite element simulations and computer numeric machine control. Form finding and structural design are closely interlinked. An optimized data exchange scheme made it possible to repeatedly read the complex geometry into a finite element program to analyze and modify the critical points of the model. In parallel, the glued and bolted joints were tested experimentally and the results included in the structural calculations.

ICD ITKE Research Pavilion at the University of Stuttgart

The plates and finger joints of each cell were produced with the university’s robotic fabrication system. Employing custom programmed routines the computational model provided the basis for the automatic generation of the machine code (NC-Code) for the control of an industrial seven-axis robot. This enabled the economical production of more than 850 geometrically different components, as well as more than 100,000 finger joints freely arranged in space. Following the robotic production, the plywood panels were joined together to form the cells. The assembly of the prefabricated modules was carried out at the city campus of the University of Stuttgart. All design, research, fabrication and construction work were carried out jointly by students and faculty researchers.

ICD ITKE Research Pavilion at the University of Stuttgart

The research pavilion offered the opportunity to investigate methods of modular bionic construction using freeform surfaces representing different geometric characteristics while developing two distinct spatial entities: one large interior space with a porous inner layer and a big opening, facing the public square between the University’s buildings, and a smaller interstitial space enveloped between the two layers that exhibits the constructive logic of the double layer shell.
