A large three storey single family home in Wijdewormer of about 600 m2 of floor area had several design aspects posing challenges to prefabrication in timber frame. The layout featured large open spaces, most notably, the first floor which is all one open space of 160 m2 with only 4 visible posts. Local contractors did not see a way to build the house in timber frame but the engineering team in ZTC developed solutions with steel beam reinforcement of the structure and use of CLT panels.
Extremely large sliding doors and windows (up to 5.8 m in height) posed challenges that the experienced installation team handled. The flat roof had to be designed for living roof installation. The design also featured hidden gutter downspouts for clean lines in the exterior.
