New Franklin elementary school, Mannheim

The Franklin district is the largest conversion area in Mannheim. Housing and living space for over 9,000 people will be created here in the future. As a flagship project, the city of Mannheim has built a four-form entry elementary school for up to 448 pupils in all-day operation, which was put into operation at the start of the 2023/24 school year.

The three-storey building in sustainable timber-concrete hybrid construction with a photovoltaic system offers space for 16 bright classrooms in a modern cluster structure, which are clearly visible from the outside thanks to the individual roofs. The building also houses the school library, a research room, a large canteen and administrative offices. A new large gymnasium is directly adjacent to the building. It will also be available to sports clubs in the future.

It is a hillside building with a height difference of one storey - basement and ground floor in in-situ concrete construction and joint-free.

The accessible sports hall roof is designed on the load-bearing side for use as a recreation area. By choosing a narrow grid, the height of the long-span glulam beams required here could be reduced to a minimum. The maximum span is 25 m.

A solid first floor was planned for the 4-stream comprehensive school due to the earthquake load. The classrooms on the first floor are housed in modular timber buildings with pyramid-shaped roofs, which are connected in the middle zones with a pure timber-beam ceiling. In order to meet the building's acoustic requirements, stacked board ceilings with integrated acoustic milling were used in the solid timber houses.
