The Lancy plateau offers a heterogeneous urban configuration. The confrontation of the third zone of development with the recent completion of several high-rise buildings faces the last rural district of the neighbourhood (4b). As such, the townhouses created by Christian Dupraz play on this morphological complicity and constitute through their emplacement and chosen form, a clear delineation of the street front and the alignment they suggest. Thought of as four independent homes, they are nevertheless interconnected to form a single unit, a "monolithic" architecture in line with neighbouring volumes.
The layout of each house offers two levels above ground, articulated around a central interior patio of small scale. This "skylight" separates the different uses of the kitchen and living room on the ground floor and the bedrooms and bathrooms above. Here, it is a case to affirm the window and its frame as the repetitive pattern of the composition of the facades. Composed of large sandstone (Algeria) frames, they draw along the plastered facade, the pace of openings of the two main elevations. While the street imposes a certain rigor on urban landscaping, the back of the building offers private gardens where the vegetation is expressed.
