Waterfall Gully Extension

A House Extension to an existing family home on Waterfall Gully Road in scenic Waterfall Gully focussing on adaptive re-use and sustainability. The existing house was designed and built in the early seventies in a builder’s version of a Frank Lloyd Wright house, spanning over first creek in a beautiful natural setting. C4 architects negotiated difficult, very stringent planning rules in order to increase the accommodation for the growing family. The result as a cantilevering bedroom and study wing that overlooks the lush natural setting and careful re working of interior spaces to make the most of the natural setting. The cool local climate required a strong focus on sustainability in the design from the outset, with limited access to natural winter sun due to the sites location. Sustainable design principles included maximising the north sun access, heavily insulate the existing building fabric, re-double glaze all windows by re-using / recycling the existing timber window frames, high level automated awning windows for summer ventilation, incorporate solar power, expand the cliff side cellar and re-use the existing building fabric as much as possible.
