ØSS 5 is located in Ørestad, the newly developed part of Copenhagen, and is situated on a corner, shaped like an angle where the facades follow the movements of the streets. The main body of the building, which has 108 housing units distributed on nine floors, is elevated on the heavy base which is developed for commercial use.
One of the very main concepts of the building is to make a clear architectural distinction between the housing units and the commercial base, the base being withdrawn from the street façade, resembling a cave with its irregular openings. The facades of the upper storeys are composed of an underlying glass prism combined with a screen of metal frames and wooden shutters.
The space between the glass and shutters is filled with a mix of indoor space, outdoor balconies and voids, creating a dynamic interaction between inside, outside, neighbours and the street. The expression of the main facade varies as the sun rises and sets, as the light crosses the reliefs during the day.
