Quinees is a shared family holiday retreat in the Blue Mountains. The design seeks to provide the original weatherboard residence with an environmentally sensitive addition. It includes a new master bedroom with ensuite, main bathroom and second living area opening onto a deck and outdoor area. The northern orientation of the addition provides a series of light filled spaces, an improvement over the existing south-west facing living-dining area. Through the use of durable materials, passive solar design strategies and hydronic floor heating, Quinees is a high performance, low environmental impact solution.
