Hot Flat is a city apartment building for five to ten families.
One of the principal concerns of the design was to make each apartment as large as possible for as little money as possible. Factory halls throughout the world that have been turned into living spaces provided a role model for this. Another fundamental concern was shaping and directing attention to the connections and transitions between the private sphere (the apartment) and the public sphere (the city).
The common rooms and the roofed-over courtyard are clearly sculpted and identifiable. The supply connections to the city are clearly visible.
Inside the building, however, the apartments comprise only the four walls. They have a floor space of 164 square meters and a height of five meters, remain without form, and are unfinished spaces that can be designed by the owners and expanded to include a second floor, creating a living space of 282 square meters.
The only permanent fixtures in the flats are the connections to the city’s media: telephone, TV, video and stereo equipment.
The building is made of steel, with concrete and other prefabricated parts.
A balcony runs throughout the building as a common space. The flame-shaped glass roof is the fixed form of the “opening fire.” It extends as a cover over the courtyard and cuts through the apartments on the upper floors. The hoist used for construction will remain as a freight hoist, which means that the balconies can be used as either gardens or parking spaces - even on the fifteenth floor.
