Cartoucherie Wood’art Eco District, Toulouse (FR)

The mixed-use eco-district “Cartoucherie Wood’art” will be built on a former industrial site on the left bank of the Garonne with a total of 3,100 m² apartments, 6,000 m² of commercial space and public facilities for schools, sports and leisure. The nine-story hotel tower and the two residential complexes that we have planned are part of the award-winning project in the Adiv’bois national competition in France. 75% of the buildings is constructed in timber – an increasingly popular choice in France.

 

Divided Master Plan

The master plan divides the 13,000-m² area into two sections: The ten-story hotel tower enhances the bustling Place des Halles to the east; the two-story residential buildings lie on the quieter west side. All buildings are connected by a common, grassy ground level which houses retail spaces and public facilities. The undulating gardens are visible from the square, providing shared meeting points for residents.

Hotel in modular Timber Construction

The hotel is built out of three-dimensional, prefabricated timber modules; the floors and walls of the residential buildings are made of prefabricated timber elements. This construction not only has a very positive effect on the energy use and the indoor climate, but also reduces construction time and thus the costs. In the hotel lobby, on the facades, ceilings and balconies, wood creates a pleasant ambience and a feeling of cosiness.

 

Facades with Terracotta Slabs

Along the paths and passages of the tower and in front of the loggias of the apartments, the façade is clad with terracotta slabs following the local building tradition. Thanks to its urban, architectural and ecological approach, this outstanding project meets the needs of all users.

Untreated Wood in the Apartments

In the apartments, untreated wooden surfaces offer a natural, healthy living environment for all the senses. Seeing, touching, smelling – wood arouses emotions and generates well-being. Underfloor heating connected to the network of the Eco Quarter spreads mild radiant heat and increases this effect even further. Partition walls made of CLT (cross laminated timber) allow a modular construction and, if required, flexible adaptation of the apartment floor plans.

Modern Timber Construction Technology

Isometry of the overall project
Modular construction: two-dimensional for residential buildings, three-dimensional for hotels
The modules are prefabricated in the factory and delivered to the construction site ready for assembly.

Apart from the development core made of concrete, the structures consist entirely of wood, with load-bearing walls and floors in CLT and non-load-bearing facades made of wood frame walls.

From the first floor upwards, apart from a concrete access core, the entire superstructure is pre-fabricated: with two-dimensional modules (floors and walls) for the housing and three-dimensional modules stacked on top of each other for the hotel rooms.

The prefabrication of the individual modules means short assembly times on site, less noise and dust pollution for the residents and enormous ecological advantages. Wood stores carbon dioxide, is regionally available and renewable and saves energy thanks to its excellent thermal insulation properties.

The residential district of La Cartoucherie shows that wood is an excellent building material, not only because of its ecologically sustainable qualities and its positive effect on the quality of living but also due to its affordability and constructional properties in large-scale, urban buildings.
