The project is a collaboration between architects Partners Hill, Ronnen Goren of Studio Ongarato, and Trace Streeter. Described by the firm as a purpose-aligned container for living, nurturing, learning, and entertaining, “The Longhouse is a study in inclusion where a boutique farm, garden kitchen, cooking school, reception venue, and home are consolidated within a single 110 meter long mannered shed.” Sitting on a 20-acre parcel of land, the building forms a datum line in the middle ground, echoing the horizon beyond; its rectilinear form is softened by the surrounding hills. Because of the shallow planting depths and hostile weather conditions of the area, the built form of the greenhouse had to be “big enough and protected enough for the landscape to flourish inside,” the architects explain.
The shed is enveloped in a translucent glass-reinforced polyester skin; with smart gel-coated cladding providing “different levels of UV and infrared resistance and panels with different finishes developed to optimize solar penetration and shading,” they continue. Sitting on minimal footings with a gravel floor, the structure was built to passive house standards—an energy-efficient construction concept composed of several strict performance requirements. ”Economy and sustainability underpin the project,” the architects remark. The impressive 1050 square meters roof harvests rainwater, both for demand use and bushfire defence. Large openings and high windows frame views of the skies and the countryside beyond while controlling ventilation.
