The roof was pitched upwards to the north to allow for high windows so as to let in northern winter sun but at the same time not be impacted by the neighbouring home. This meant solar panels had to be placed on a rack to get northern exposure. A pergola was placed on the east to shade the large eastern glass door facing the view & accessing an outdoor entertaining area.

The climate was quite cold by Australian standards. The northern side of the block faced a neighbouring house with a long, stark brick wall. Additionally there was some shading on this elevation by trees. The best views were of the garden to the east.
