A sustainable development in stages

5082 Mt. George
Completed: December 2011
Cost range: $300,000 – $350,000

The brief for the project was to consider a sustainable development in stages.

The first stage was for a living, dining and kitchen, main bedroom, en suite and walk in robe. It was to connect to an existing dairy which has been converted to a  modest home. The second stage is to modify the dairy to house a children’s’ wing. The third stage will include a library and games area.

The most dramatic aspect when one approaches the site is the view to the north. Presently the house has a courtyard to the east that overlooks this view of rolling hills and a dam. Stage one has been set across the front of the courtyard so that it takes maximum advantage of the view and connects directly to the existing house. Large doors and windows on the north and south facades of the addition gives a transparency that still allows commanding views through the building.
