Inclined, round, smooth and made of high-quality architectural concrete: Hungary’s largest nursery is unusual from a geometric point of view

Children enjoy playing with it, teachers recommend it: the shape sorting box. Based on the popular toy, the architects who conceived the new Meséskert nursery designed the play areas on the top floor as a triangle, circle, and square. These allow the children to play outdoors in the summer. From an architectural point of view, the new four-storey building blends in perfectly with the high-rise surroundings and replaces the old kindergarten, which was 60 years old when it was torn down.

The challenge for the formwork was pouring the 5.15-metre-high architectural concrete walls surrounding the playgrounds. They are all inclined and have rounded-off corners, and in one case a conicular shape.

WTS wall formwork system 

Due to their unusual geometry, these inclined walls were all poured using the WTS wall formwork system. The formwork was pre-assembled and the beams equipped with shuttering panels that were precisely cut to size and the rounded sections were precisely bent to match each radius. Like the slabs below, the surrounding slab was poured using the MevaFlex system. The box-outs required very careful planning and working procedures to guarantee a completely flush closure between the slab and the box-outs. The walls were partly formed using the AluStar system on the façades and the other storeys.
