The property is an apartment building from 1900 in Kvadraturen. The project consists of a total renovation of the existing building and modernization of the office areas. To achieve this, it will be necessary to build new decks facing the backyard at the same height as the decks facing the street. The inner courtyard will be converted into a glazed atrium, and the office areas will have a new facade towards this room in the same position as today – the existing stairwell will be preserved. A clear distinction must be established between new and old during the rebuilding. The facades will be restored to their original appearance.
