Sustainable principles in a minimalist style

Somerton Park SA 5044
Completed: March 2010
Cost range: $750,000 – $800,000 

The clients brief called for an innovative design solution focussed on sustainable principles in a minimalist style.
The property has a narrow frontage to north. Two challenges emanate from its configuration. Firstly, the garage can tend to dominate the frontage unless handled sensitively, and secondly, northern exposure to living spaces can be limited unless carefully considered fro the outset. The solution has been to set the garage half a level below ground which allows the living spaces to be located above - half a level above ground. This not only hides the garaging to a large degree but it also provides the maximum northern exposure to living area and gives it prominent views into the courtyards.
To further improve solar access the plan shape is in the form of an extended “c” which gives the main bedroom northerly aspect and centres all spaces into the sheltered swimming pool court.
The linear gallery on the western side is a visual as well as circulation spine which also acts as protection from the summer afternoon sun to other rooms in the house.
