The Entfelden school required additional space to ensure the provision of education for future generations. As part of the masterplan for expanding the school facilities, the existing upper school building was extended and refurbished with a two-storey rooftop addition.
By using a hybrid load-bearing structure made of steel with timber–concrete composite floors instead of a conventional steel beam construction with composite metal decking, it was possible to generate numerous added benefits within a cost-efficient solution – including the careful use of sustainable material resources, an optimised construction process through prefabrication, and, not least, improved architectural refinement.
