The residence meets the energy consumption criteria that applies to the “low energy” category. The volumes are designed to ensure a favourable relationship between the built volume and the weathered surface of the external envelope. In addition to optimal peripheral thermal insulation, all units benefit from a double-flow ventilation system with energy recovery. The double-glazed openings are protected by external blinds to control the sun’s radiation during the warm season.

The residence is listed in the Guide d’architecture contemporaine du Luxembourg, which has become the reference guide to contemporary architecture, engineering and urban planning in the Grand Duchy of Luxembourg. Designed by the architect Michel Petit, the building is characterised by its location at the bottom of the Alzette valley. The upper floors are dressed in raw concrete and are distinct from the main façade below. The central, fully glazed section illuminates the vertical circulation between the main bodies of the building. Horizontal access to the housing units is provided by corridors between the rock and the housing blocks. The corridors are illuminated on both sides by large windows on the side walls.
