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.
