Bereenstrasse 31 is a new built project in Zehlendorf area. The surroundings are a specific part of Berlin including lakes and green area, including many villas and families. It is ­situated within the former West Berlin, not far from the green area Grünewald and the lake Schlachensee. Mexiko Platz is a connection point for the S Bahn and the station has an interesting organic roof feature which brings to the whole piazza a feel of dynamism. From there Bereenstrasse grows and connects directly to the site number 31. The project aims at replacing an existing old villa into a 6 flats buildings. The aims is to integrate a quality architecture within the local context. Many options have been investigated to explore different styles, site integration, and inner architecture. The core of the buildings and balconies are designed in a simple form as a base to a 3D concrete roof shell, referencing Mexiko Platz station, and creating a simple and unique feature. The inner space under the shell becomes curved and fluid and connected to a top terrace within the trees.
