Description

Strongly shaped by the neighbourhood’s development plan, the project challenges the rigidity of the imposed repetitive slab blocks. A folded façade explores tangential orientations and the depth of the site. This geometry maximises sunlight exposure and views while reducing noise from Route de Ferney and preventing direct overlooking between buildings. All apartments benefit from at least dual orientation. Each is organised around a living room and eat-in kitchen pair that can be partitioned and which opens onto a central loggia. The larger through-apartments are conceived as adaptable units, thanks to a double entrance hall system allowing future subdivision. Exterior access galleries connect the loggias, encouraging social interaction, providing solar protection, and facilitating façade maintenance. Two reinforced concrete cores integrate vertical circulation and wet rooms. Around these structural spines, a four-metre-wide band accommodates living spaces and bedrooms. It is built with a hybrid timber-concrete system using point-supported timber columns and a lightweight timber façade. The access gallery, made of cast-in-place concrete, rests on an independent structure integrated into the façade and contributes to its architectural expression. The building, with six storeys plus a recessed penthouse, is articulated in three layers: a concrete base, a timber main volume punctuated by concrete balconies, and a matte stainless-steel-clad penthouse.
