The project is a three bedroom retreat to accommodate a couple and their visiting children and grandchildren.The site is located at the edge of a natural eucalypt valley between Leura and Katoomba, 100 kilometres west of Sydney in the Blue Mountains. In response to this edge condition, a two part form was developed. These parts are distinguished in plan, elevation and structure. The living areas are contained within the steel framed structure embracing the bushland. Within this room are places for activity and contemplation.The bedrooms are contained within the stud framed block, offering privacy and framed views of the bushland beyond.The various level changes in the house offer spatial connections between the parts and frame shifting vistas of the valley beyond.The house is designed to take full advantage of the sun during winter whilst using cantilevered roofs and external metal blinds to control the sun at other times of year. colla
