Four NOC*NSF sports halls and the swimming pool are clustered. This multifunctional sports facility (MFS) has its own construction principle and dynamics and is sound- and user-technically separate from the rest of the building. During the day, the sports halls are used both by primary school pupils from the area and by the KJC. In the evening, local sports clubs can make use of the sports centre. The sports halls can be combined 2 by 2. The large round windows in the swimming pool and the sports halls consist of aluminium profiles in bronze, filled with insulating glass, which is then provided with a matt foil. This allows filtered daylight to enter, without you being able to look inside or outside. The swimming pool has a arched ceiling with a skylight, which brings even more daylight in.
A pattern of yellow diamond shapes on a brown background characterizes the brick façades around the building. With a view to pollution, the masonry pattern runs from dark to light from bottom to top. Eyecatchers are the large round windows in the north façade, which provide the sports complex with daylight. In more places, semi-circular forms enliven the façades.
At the east, south and west façades, an overhang with a terrace underneath softens the transition from inside to outside. At the same time, the overhang improves the indoor climate of the school building and makes cooling less necessary. The east and west facçdes on the first floor have windows with vertical fins, which largely prevent solar radiation.
The windows and doors are framed with aluminium profiles. Rohmer explains her choice: "With aluminium you can make all shapes, such as the circles in the north façade. The bronze colour of the windows fits nicely with the façade panels and the masonry. They are low-maintenance and offer good sound and thermal insulation."
