The concept of the Atreeum office building is based on the principle of a Moroccan Riad, which forms a protective wall on the outside and lively, differentiated green atriums on the inside. The outer skin of the Atreeum consists of a clinker brick façade with a minimalist opening structure that envelops and protects the building. Inside, the volume dissolves into horizontal layers.
Numerous balconies and roof terraces are oriented towards the inner green spaces and enable the use of these landscaped green areas. These green inner courtyards form the significant heart of the building. The roof terraces offer special recreational areas with pavilions and workspaces surrounded by greenery. A retention and evaporation concept is integrated into this overall concept, which creates a healthy, natural microclimate in the courtyards and inside the building. In this way, this building can make a contribution to sustainable architecture.
The result is a green working oasis in an urban context.
