Wulumuqi Road Apartment

The alteration and addition of Wulumuqi Road Apartment took advantage of what was an interpretation of a local policy of urban beautification in the city of Shanghai. There was a city-wide policy (平改坡) where pitched red-clay tiled roofs were being added to the flat reinforced concrete roofs of modern commune housing that were considered dull and devoid of civic or traditional character. The drab housing that qualified for this alteration tends to be housing blocks that were built hastily by the Communist Party in the 1940s and 50s. However, the site for this project was a particularly poorly built Lilong housing block of the 1930s.

In the re-design of this top-floor apartment, the original flat roof was partially demolished to give way to an attic addition. This attic took reference from the vernacular form of the dormer window found in the neighborhood. The triangular form of the dormer window roof served as an archetypal form that was rigorously applied to this project – with all of its implications of structure, envelope and geometry. The addition of an attic bedroom and study meant that the main floor can be freed up as an enlarged loft-like living space with an open kitchen, instead of its original walled up bedrooms and living room.

On a formal level, the triangulation of the roof plane – necessary in a dormer window in order to bring daylight into the attic – was extrapolated to give shape to the ceilings, walls and new staircase. Indirect artificial lighting was achieved by concealing lights along the edges of overlapping triangles that made up the walls and ceilings. The staircase took on a similar form, where each tread and baluster was separately articulated to mark the culmination of these graduating and transformative triangle surfaces.

On the programmatic level, the new continuous form not only gave rise to the fluid expression of the staircase, but it also gave an organizational logic to other functional needs of the apartment, such as roof level access to a small outdoor roof patio, as well as a passively cooled interior, where hot air is able to rise and escape through the new attic windows. The rest of the apartment was kept relatively plain and simple, where the existing industrial steel windows, wooden flooring and white plaster walls were retained, in anticipation of the unfolding elements from the new attic space.
