The octagonal living room is the concentrated core of the apartment, which is highlighted by polygonal formal and aesthetic interventions: the existing massive window frames were visually reduced and translucent roller blinds filter the leaves of the garden trees into a powerful atmospheric green veil. The ceiling is articulated in diamond-shaped segments making for a strong spatial presence that is reinforced by indirect lighting and a reduced material palette. In the otherwise homogeneous spatial envelope, the ceiling is reminiscent of a dramatic, icy winter landscape and at the same time contrasts with the green glimmer of the window surfaces. The spatial clarity is effectively reinforced by the integration of all technical infrastructures into the walls and ceilings, by the detailing of junctions, as well as by the reduction of materials to a high-quality minimum.
The apartment is located in a high-rise residential building in the former French Concession area of Shanghai. From a dark and narrow corridor one enters the hall, from which the adjoining rooms open. In the centre of the main room stood a column, to which the architects added new wall elements, to define different functions and to complete the geometry of each of the adjacent rooms: the entrance is half a hexagon, the hall a pentagon, followed by the central octagonal living room and the rectangular kitchen.
