The concrete pavilion Betonoase was opened yesterday in Berlin’s Lichtenberg district. The building, which will be used as Youth and Family Center, features outside walls and cantilevered canopies made of infra-lightweight concrete. The Betonoase is thus the first public building to be erected in this innovative way, making use of a material that is load-bearing and insulating at the same time. We are proud to have worked on this project together with Gruber + Popp architects.
During implementation, schlaich bergermann partner encouraged the architects in the idea of building a monolithic concrete structure. For the construction of the single storey pavilion, infra-lightweight concrete was not only used for the 50-centimeter-thick outer walls, but also for the canopies, measuring 32 centimeters. The material has a dry density of only 700 kg/m³ excluding the galvanized reinforcement steel. Since there is no standard yet, the use as a highly heat-insulating monolithic building shell had to be approved individually for this project.
The close cooperation with the client and the architects has resulted in an innovative single-shell, exposed concrete structure. With its completion and opening, the Betonoase now stands exemplarily for further applications of this material.
