Competition 2021

Competition launched in 2020 in the Bastide-Niel UDZ in Bordeaux, the Bellecour studio responded on block B127 with Sogeprom and Altae. One of the main challenges of this operation was the integration of a multifunctional program within a complex geometry.
By placing plants as a mean of structuring the project, the program invested seven buildings erected along a green canyon, making it possible to fight against the heat island effect. The project assumed a contemporary, white, refined style, revealing its blond heart, a reminder of the history of the city.
The program mainly made up of homes with 194 housing units (collective, coliving, integrated individual housing), also included 1,700 square meters of offices, 2,000 square meters of shops and services, as well as a parking lot with 400 shared spaces.
The construction system favored structural diversity, adapted to suit the different situations of the project with a significant share of structural wood, bio-based insulation on most of the project, raw earth in order to bring the maximum effort to the low carbon. For certain structures, such as the tallest facades or the car park, absorbed in the middle of the program, being under strong regulatory pressure, the use of heavier structures remained the appropriate technical solution, but using prefabrication. One way to introduce off-site construction on non-standard structures.
The project was therefore based on a flexible structural mix, adapting construction methods to ensure a good technical, regulatory, environmental and financial balance, in a continuity of architectural image.
