The main focus of the project brief was to design a compact and space-saving floor plan with all the necessary energy efficient features, such as a Heat Recovery Ventilation system, well positioned for the sun and airtight building solutions to make this home healthy, comfortable and energy efficient.

The ground floor comprises of an open plan kitchen, dining and living area, plus two bedrooms and a bathroom. The laundry is located underneath the stair for space efficiency.

On the mezzanine floor are located the main bedroom, a WIR and an ensuite as well as a small gallery with a bookshelf.

The main living space and the main bedroom, have a skillion roof constructed partly with scissor trusses due to affordability.

To cut down building time the ceiling of the skillion roof is constructed with Metra panels, which make the building weathertight and hence allow to start on the interior installations much earlier.

The airtight building solution system is supplied by Pro Clima and consists of the interior Intello airtight layer as well as the exterior wall and roof underlay.

Wall and Roof cladding is Colorsteel Endura corrugated iron.

The windows are uPVC windows, double-glazed, Argon gas filled and Low-E.

The Heat Recovery Ventilation system is the Lunos system supplied by the Heating Company.

The combination of an airtight building solution system and a Heat Recovery ventilation system together with high quality windows and insulation products guarantee that this home will be healthy and energy efficient.
