The building incorporates reverse veneer construction, ‘super insulation’, innovative curtain wall window detailing, rainwater harvesting, natural gas hydronic heating, passive ventilation, low energy lighting, use of slavaged materials and FSC certified timbers. The commission included all in-built cabinetry and the freestanding timber furniture in the new areas. This was done for the studio’s most fearless client, this building demonstrates that a concrete, glass and timber structure can be built sustainably resulting in a 7 plus star rated building. Built in the sensitive heritage area of Battery Point, this addition to a 1890s weatherboard cottage is designed to be zoned into separate areas allowing maximum flexibility of use. The compartmented design allows only the areas of the building which are in use to be heated and illuminated.
