Building in wood & concrete on the shores of Lake Geneva:
Registered in the commune of Collonge-Bellerive, a few steps from the lake, the plot was developed by b29 in 2020. Initially constrained by regulations on building authorizations, the architect’s office redoubled its ingenuity to create housing that deviate from regulations on densities, using the construction principles defined by very high energy performance (THPE).
The villas thus gain in size, while being better insulated, and by articulating generous stepped facades, on the south side.
The 3 houses maximize their intake of natural light, and are protected by specific, high-performance triple-glazed glass. Roof projections on each floor serve as a natural sunshade. The main roof is equipped with heat pumps coupled with solar panels. The choice of facades highlighted the use of local wood panels. From Switzerland, the wood is transported, prepared and assembled on site. The window frames, paneling and interior joinery were all produced in the same type of wood and locally.
The building companies were selected locally in the Geneva area, and were overseen by the total company BERIC realization. The b29 office collaborated with the CONTI building thermal engineering team as well as the SBING offices for the calculation of the supporting structures. B29 developed all study phases up to the building permit, calls for tenders and architectural management of the execution works.
