The new building was intended to blend into the background of the historic monastery complex and not exceed it in height. Therefore, in contrast to the existing pitched roofs, a building with a low-pitched roof was proposed. Cladding with the existing plain tiles is not possible with this low roof pitch, so a double standing seam stainless steel roof was chosen.

The roof is designed as a cold roof with a straw-insulated floor slab and a raised rafter roof to create the roof pitch.
Fire protection requires that the room partitions below either extend directly below the roof skin or that a room-enclosing fire-retardant finish be constructed. In order to achieve fire resistance class REI30, the straw-insulated construction was clad on the underside in two layers (OSB and GKFI board) and the room partitions were connected to it.
