Based on the architectural competition won together with Gruber + Popp Architekten, schlaich bergermann partner have developed the structural design for "Betonoase" youth center in Lichtenberg district of Berlin.
The special feature of the single storey building is that its external walls and roof projections are built with so-called infra-lightweight concrete (ILC) with a dry density of only 700 kg/m³. Due to its low thermal conductivity, the structural and heat insulation requirements can be met by a monolithic concrete structure without any additional cladding. This makes true all-sided exposed concrete a reality.
As the infra-lightweight concrete with a density of 800 kg/m³ or lower is not covered by current engineering codes, a special approval by the building authorities was required, which involved full-scale structural testing of members.
Lichtenberg city council proved to be a truly courageous client bringing the innovation project forward in a team of architects, engineers and other stakeholders. To schlaich bergermann partner, the project is an important milestone in establishing the monolithic construction principle in the industry.
