of the classical building core, lead via the platforms to the adjacent
floors of offices.
The fifth floor has a sky lounge with panoramic windows and a
spacious external terrace. The lounge is openly linked to the atrium
space and, like the offices, may be reached on foot via the ‘tree stairs’.
In every part of the building – from the supports, beams, windows,
and doors, to the claddings and railings – wood is visible in all interior
areas. Each of the building’s inner corners contains a building core
with a safety staircase and elevators.
The entire interior design concept, as well as the development of the
new office worlds for Vattenfall, was developed and accompanied in
the implementation by de Winder Architekten Berlin.
The ‘Solitaire’ building
The Solitaire building has a two-storey entrance lobby with a clear
height of seven metres. Floors two to seven contain offices, while
the ground floor houses gastronomic, commercial, and retail spaces.
Here too, wood is a ubiquitous architectural and design element. The
building is entered from the new urban plaza. Vertical access is by
means of a central core with a safety staircase and two elevators. The
landscaped outside space of the lounge, on the building’s roof, has a
garden-like quality to it.
Both the Carré and the Solitaire building have a flexible modular
ground plan on all levels. This can be adapted to individual
requirements. With an extensive deconstruction concept, the issue
of circularity was integrated into the planning at a very early stage.
The flexibility and reusability of the building is ensured, among other
things, by avoiding load-bearing interior walls, a room height of at

The German Sustainable Building Council (DGNB) certified the
project as Germany's most sustainable building in 2022.
