CITY SCHOOL CENTER ALTONA, HAMBURG, Germany
New construction of a sustainable school building

The center Altona marks one of the most important urban development projects of the Free and Hanseatic City of Hamburg. On the grounds of the former rail depot Altona an attractive and lively new residential district is being developed. There, on a 3,500 m² site a modern and sustainable school building [DGNB Gold Certification] for about 1,100 pupils is planned. The client is SBH Schulbau Hamburg.
In 2015 the architectural studio LRO Lederer Ragnarsdóttir Oei, Stuttgart, won the 1st prize in the architectural competition for the district school in Mitte Altona. DGI Bauwerk, Hamburg, has successfully bid for the contract for the construction planning and realisation.

The urban block structure and the layout of the plot require a compact design. A central internal staircase over all storeys forms a kind of vertical foyer – the heart of the building. A skylight placed at the highest point ensures that daylight falls into the lowest floor. 42 regular classrooms are grouped into compartments with up to six classes. On the upper floors outside clearances allow the exposure of the core zones.
The planned facade of red brickwork is naturally integrated into the surroundings with its residential houses and commercial units.
