Background

This modest sized 3-bedroom home by Australian standards, in the relatively cool climate of Leura in the Blue Mountains NSW. The client chose an existing Blue Eco Homes concept design that they wanted built to the Passive House standard. 

Challenges

The site sits on an east west axis with good northern exposure, however a close neighbouring house on the north presented a less than desirable view.

Fortunately, the home design chosen suited the site quite well by simply mirroring it. To minimise the view of the northern neighbouring house however, northern windows had to be high & minimised. Due to the cold climate, it took a delicate balance to achieve the Passive House requirements without significant additional cost to the building envelope. This has been achieved and the house is now under construction.
