An exploration of thermal prefabricated technology, this formally simple but performance-rich project sits confidently in its beachside location. Experimental use of Structurally Insulated Panels (SIPs) is combined with a portal framework of black steel. Interiors are dark and moody but contrasted with functional timber joinery to strike a balance and allow for the occupants’ personalities to be expressed. On a tight budget, this is a home to celebrate for its brave attempt to test new building methods and materials.
