The hallmark of this project on the top three floors of a 1950s building is light and an ongoing relationship between inside and outside. A bookshelf staircase connects the entrance floor to the upper floor, originally the building's terrace which has now been redesigned as a greenhouse and which houses the study while from the roof of the glass-enclosed space another terrace has been created. The renovation project also creates continuity between the contents and the container of which the most interesting construction elements such as the original windows and the Venetian blinds have been carefully preserved.
