Breezway Altair louvre windows have been extensively installed at an award-winning house in Wahroonga, Sydney to assist with natural ventilation.

Designed and built by Chateau Architects and Builders, the home, which is located in the leafy suburbs of Northern Sydney, reflects a European modernist architecture. This substantially glazed and cedar-clad home at Wahroonga has become an inclusive and open hub for the family with the open layout inviting the surrounding suburban but extremely private landscape into the home through north and east facing floor-to-ceiling glass doors. When opened, the walls appear to dissolve, facilitating a natural indoor-outdoor flow.

A central void space functioning as the hub of the home is dominated by a 5.4m high joinery element projecting through to the upper level. This space is lit from above by four substantial skylights arranged to create a striking geometric form in the ceiling, allowing a dramatic play of light, space and form to the areas below. The bedrooms are all naturally lit by panoramic large-format windows.

Apart from the large sliding glass doors, all natural ventilation through the home is achieved by Breezway Altair louvre galleries either in glass or with naturally anodised blades to match the anodised aluminium window frames for areas where privacy is required. Featuring a modern architectural aesthetic, the Altair louvre galleries are strategically located in each room and space to facilitate horizontal cross flow ventilation as well as vertical airflow through the central void space. Thanks to the extensive use of Breezway Altair louvre windows, the house breathes naturally year-round and is always thermally comfortable.

Some of the awards won by the Wahroonga house include: 2013 NSW Master Builders Association (MBA) Awards: Design and Construct House $1m-$2m Category Winner; 2013 NSW Housing Industry Authority (HIA) Awards: Custom Built Home $1m to $2m Category Winner; 2013 NSW Housing Industry Authority (HIA) Awards: Custom Built Home of the Year Overall Category Winner; and 2013 NSW Housing Industry Authority (HIA) Awards: Home of the Year Outright Winner.
