On a narrow plot in the midst of a residential area composed of villas and small buildings, the project replaces a modest house. Small, but wide open to a beautiful landscape, the location itself determines the volume and organisation of the building, with a “butterfly” plan that takes advantage of regulatory constraints to accommodate seven generous dwellings yet leaves enough room for a large garden.

The apartments are distributed in pairs, two to a floor, allowing each flat to benefit from a three-sided orientation with balconies. There is only one apartment in the attic, giving the owner a perfectly panoramic view, with a generous terrace overlooking the neighbourhood.

The dark exposed concrete façades are structured in superimposed bands of varying heights, which alter the size of the windows to suit domestic use. These smooth concrete bands emphasise each floor, contrasting with the roughness of the panels separating the windows that are sandblasted to reveal the aggregates and materiality of the concrete.

The alternating position of the windows between the different levels tempers the repetitiveness of the design and is intended to offer each apartment and every room the best possible view. With respect for the context, the building remains dark in colour to highlight the vegetation colonizing the residential hillside.
