Extruded House

Extruded House is a showcase of off-form concrete as both a structural and finishing solution to the concept of an open plan room. The geometric form of the concrete pitched roof and walls is extruded from the original profile of the building it connects to. The structural engineering resolution of this is complex and required an unusual full arching analysis of the roof form with discreet locating of critical tie elements to control cracking and prevent spread of the roof. The sloped roof pitch was difficult to construct in off form concrete and this was recognised in the project as the winner of the Concrete Institute of Australia, Excellence in Concrete Award NSW 2019.
