Wood’Art, ZAC de la Cartoucherie, Toulouse (FR)

The mixed-use eco-district “La Cartoucherie” 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 “Wood’art” complex that we have built – a nine-story hotel tower and two residential buildings – is 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

Together with Seuil Architecture, we have built a complex with flats, shops and a hotel on a 13,000 m² site. On the edge of the public square and lined by the tram axis, the nine-storey hotel tower sets a clear accent in the new district. Behind it, on the quieter west side, two residential complexes rise on a plinth with shops and public facilities. The lush green gardens on the roof of the plinth are visible from the square and provide common meeting spaces for the residents. They also form a reserve for biodiversity and limit the creation of heat islands. At ground level, a pedestrian street connects all the buildings, widening in some places to create space for café terraces. The buildings are 76 % timber constructions – a topic that is gaining more and more importance in France.

Hotel and residences in modular timber construction

The hotel and the residential buildings are constructed from two-dimensional, prefabricated wooden modules. This construction not only has a very positive effect on the energy indicators and the indoor climate, but also on the construction time and thus on the costs. Wood also provides a pleasant ambience and a high level of living comfort in the hotel lobby, on the facades, ceilings and balconies, both visually and haptically. The building complex consists of 76 % wood (5,300 m³). The material is used wherever its use makes the most sense.

 

Facades with Terracotta Slabs

Terracotta shingles, echoing local building traditions, form a double skin of façade along the paths and passages of the tower and in front of the loggias of the flats. The visual unity of our architecture creates a distinctive reference point for the neighbourhood, while the diversity of the public spaces, the permeability of the blocks and the social and functional mix of the buildings guarantee a lively environment for the users.

Untreated Wood in the Apartments

In the flats, untreated wood surfaces offer a natural, healthy living environment for all the senses. Seeing, touching, smelling – wood awakens emotions and creates a sense of well-being. Underfloor heating, which is connected to the Eco-Quartier’s heating network, spreads mild radiant heat and increases this effect even further. Partition walls made of CLT (cross-laminated timber) enable modular construction and flexible adaptation of the flat floor plans if required.

Modern Timber Construction Technology

Isometry of the overall project
Modular construction for residential buildings and the hotel
The prefabricated modules are delivered to the construction site ready for assembly.

Apart from the concrete access core, the building structures are made entirely of wood, with load-bearing walls and floors in CLT and non-load-bearing façades of timber frame walls.

The two-dimensional modules (floors and walls) are prefabricated in the factory. The prefabrication of the individual modules means short assembly times on site, less noise and dust pollution for local 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.

The common base connects all the buildings. The basement houses shops and public facilities, while the park-like planting above provides an attractive recreational space for all residents.
The café enlivens the ground floor zone and, through its garden, also the square in front of it.
