Integrated Secondary School Wartiner Straße, Berlin, Germany

A new integrated secondary school for up to 725 pupils was to be built in the growing Berlin district of Lichtenberg. Architect Ulrike Vogel from the responsible architectural firm NAK Architekten describes the challenge: "It was clear from the outset that our design had to be as compact as possible due to the limited plot of land and the requirement to construct a three-court sports hall and a sports field with a running track in addition to the actual school building."
 

The required compactness was achieved by moving the school and sports hall slightly away from each other and then reconnecting them with a school street that runs through both buildings. This also gives the ensemble a clear division of the outdoor spaces into schoolyard, sports field and forecourt - and blends harmoniously into the urban context. In addition, a surrounding plinth emphasizes the visual cohesion of the two buildings.

A textured formliner from our RECKLI SELECT series was used for this project. To achieve a façade with both visual depth and long-term resilience, the planning team opted for the 1/316 B Pennsilva design in coordination with the client, RECKLI and the precast plant Geithner Bau. The structure’s rib-like pattern and coarse fracture texture lend the concrete a natural, almost timber-like character. Combined with the sand-colored tone of the precast elements, the result is a bright, welcoming appearance that softens the overall geometry of the building. In addition, the irregular texture offers a practical benefit — it makes the surface less appealing for graffiti.
