ALBI

”

On the north bank of the river Tarn, 400m as the crow flies from Albi’s celebrated Cathedral of Saint Cecilia, Pratgraussals sits in a bend on the river on the site of a former quarry, latterly appreciated for leisure and nature. For the new community centre, we have proposed a building that responds to the landscape, and whose morphology allows for a variety of possible future uses. The distant spire of Saint Cecilia’s Cathedral calls for a building of great simplicity, laid out horizontally, its gallery reinforcing its pedestrian links. The powerful presence of the project characterises the site, but its architecture creates the illusion of having always been there. The sloping roofs indicate the centre, over the main events hall, and the two extremities at the south and north correspond respectively to the main entrance and the artists’ entrance. The peripheral walkway becomes a suspended canopy, indicating the entrance. The simplicity of the volumes and combination of materials offers a double scale: a domestic scale, with particular reference to agricultural buildings, and the scale of a public building open to all.

04

BUILDING DESIGN The Pratgraussals community centre is a major amenity, part of the community, inviting, conceived to cater for the wide range of events that it needs to accommodate. The brief stipulates the construction of a large hall to seat 500, plus associated services: reception, dressing rooms, technical logistics, kitchens, management, as well as the necessary external developments in the meadow to the west, with its events stage.

A hall designed both as an important piece of equipment for the Pause Guitare festival, and a welcoming and convivial building for multiple uses in the city of Albi. A simple brief for a community venue for parties, meetings, games and events for all ages and all passions.

To these criteria was added the requirement that the building be constructed in less than 11 months in time for the 2017 and 2018 festivals.

2 ROOM SETUP

3 ROOM SETUP

The centre of the project is the large events hall, whose roof makes it possible to adapt a reception area by decomposing it into three separate spaces, thus being able to accommodate a range of configurations. Particular care was given to ensure both natural light during the daytime, as well as the possibility to black out for shows or projections.

At either end of this space are, to the south the main entrance to the building, and to the north a secondary entrance, providing the option of extending the events’ space out into these two additional volumes. A broad canopy protects the southern entrance from the summer sun or provides shelter from the rain. On the north side, the canopy extends out away from the building, forming an external space like a little patio giving onto the park, which can be privatised. To the east, a functional concept provides access the entire building via an internal access passage.

WORKING PROCESS For the first step of the model, I start it from the floor layering of the building by using different type of materials of papers to indicate different floor layerings.

01

To make it more realistic, I collect some soils to indicate the subsoil under the building, together with the foundation.

02

I build them up followed by the floor plan through the columns from the foundation of the building and connect the column with the beams by using the method of timber portal frame.

03

Then, I start to build the minor white building and the walkway outside the building.

Lastly, I building all the skin of the building with all the openings and most of the components are halfopen to show the details of roof’s structure, wall, door, window, walkway roofing and structural ties.

CONSTRUCTION METHOD TIMBER PORTAL FRAME

The methodology developed was based on the following basic principles: simplicity of form, rationalized structure and efficient building techniques. The grid, defined by the building’s uses, was taken as the starting point for design.

It runs through all the components of the project, ordering the overall conception and favoring the use of serial-produced elements.

This consequently improves quality control, keeps costs in check, and optimizes construction time. The structure of the big events hall consists of timber portal frames, enabling the 24m span across the room. The principal components are pre-assembled in the workshop and positioned on site using clear and simple assembly systems.

Timber portal frame used in this building are typically used in larger industrial type construction. Timber portal frame does not have the inner or web members that a truss has and relies on rigid connection of the columns to the rafters. In addition to the benefit of more space due to the elimination of web members, portal frames tend to be less labour intensive and cheaper to construct.

KERTO BOX STRUCTURE

In between the timber box structure used in this building, there is filled with acoustic equipment to maintain the good acoustic inside the building when there is concert or some other event.

For the wall construction, there is prefabricated concrete panels as a based and filled with acoustic equipment.

34

KERTO BOX COLUMNS AND BEAMS

Kerto box columns and beams are joined by using the timber tenon joint. The joint is strong enough to carry the structure, it does not need any bolt and nut connection.

Kerto is a laminated veneer lumber (LVL) product which is incredibly strong and dimensionally stable, and it does not warp or twist. It derives its high strength from the homogeneous bonded structure.

FLOORING DETAIL The flooring of the building is fully finished by the cement. Cement could be a good choice of floor finishes for this building because it is stiffness, durability, damp resistance and fire resistance. Raw materials like cement finishing play an important role in the production process to a great extent as the success of the economy of a country is determined by the amount of natural resources held by a country within its borders.

CONCLUSION

In conclusion, the Pratgraussals events space in Albi, southern France, is resolutely contemporary in both its geometry and its proportion, while simultaneously being timeless in its use of materials. The project draws on two regional references, firstly the tobacco drying barns, with their slatted timber sidings, and secondly, the open-sided market halls, places for meeting and exchange. The space is conceived as a ‘toolbox’, which is multifunctional and can have its internal configuration modified. The volumetric arrangement is therefore organised around a large hall, which is a public space, open and accessible to all. It is the building’s uses and functions that define its form and its identity.

The integrated design approach, involving both the structural engineering and the architectural conception, has allowed for the structure to be consciously expressed. The materials are unfinished, simple and natural (timber, pebbles, zinc): signs of basic comfort and durability.

— Simplicity of form — Rational structure — Constructive efficiency The proposed construction methodology, which will reply to the strong pressures for rapid completion, is not simply a reaction to this constraint, but is the coherent result of a deliberately chosen architectural position that allows simplicity to be an end in itself for the project. This quest for the right solution is combined with a focus on the perception of the building within its environment. A building which is welcoming, bring people together, and unashamedly public.
