The method involves providing a formwork (24) for prefabricating a floor element (60). An inner surface of a bottom (28) of the formwork, on which concrete of the floor element is cast during prefabrication, is glazed. The floor element is removed from the formwork after hardening the concrete. A supporting sub structure of floors of a building is obtained. The floor element is attached on the sub structure such that a lower glazed side (32) of the floor element is facingly arranged away from the sub structure. An upper side (34) of the floor element is partially laid on the sub structure. |
