The Municipality of Utrecht is developing the new district Leidsche Rijn Centrum. Public transport facilities will be added to this district. Jo Coenen, together with AnnA architecten, designed a unique roof for the new bus station. The roof will cover four bus stops. In turn, the bus stops lie on the access tunnel for the A2 motorway and on the city rail tunnel. Cups The roof consists of a steel structure with 10 hexagonal cups. The cups are formed by a pre-tensioned membrane. The shape of the membrane is a bell shape with the lip on the underside. Triangular smaller membrane structures are present between the 10 hexagonal cups, with the point facing upwards.
