Berlin Moabit. New building attic. The client wanted a connection between the 4th upper floor and the new attic. Two generous maisonettes were created. The attic was designed as a steel construction. This allowed the special roof shape to be realised - with the aim of constructing large open spaces. The fourth upper floor was completely renovated and contained a new staircase which winds around the supporting structure of the new attic and leads into the new rooms.
