All twelve apartments at Hauptstraße 30 in the market town of Hinterbrühl are already receiving the first part of their roofs. As soon as the thermal concrete ceiling is finished, the lighter wooden roof beams will be installed to give the building its final shape. Over the last two months, three floors above ground and a basement have been built. At the same time, the staircases have been built to facilitate access to the work areas. Once the roof is finished, the next phase of construction can begin.
