A strong relationship between internal and external areas was sought for the main everyday living areas of the house, being the kitchen, meals area and dining room. Devices such as the highlight windows within these spaces allow a constant glimpse to the sky, the blurring of internal and external boundaries through the use of external materials within the house and the large openings making visual connections. The stone walls used externally have also been used internally to the south wall of the meals area and the copper soffit lining to the upper terrace runs internally in the bulkhead and ceiling to the kitchen, meals and dining room thereby blurring the internal and external areas. The ceilings within the dining room and kitchen / meals area are lined with timber battens. Along with providing warmth and detail to these spaces the timber battens also conceal acoustic insulation to assist with deadening the reverberant noise. The design and usability of the upper terrace itself was pivotal to the success of the house. It is the external area of the upper terrace that connects to extend the internal areas with the boundary between the two being blurred. A balance was reached between solar access and protection from the rain while maintaining a non-restricted view to the sky from internal areas through the use of glass roofs and automated awnings.
