An innovative design solution

Maylands SA 5069
Completed: November 2009
Cost range: $300,000 – $350,000

The clients brief called for an innovative design solution that incorporated the existing cottage and retained an attractive tree in the rear yard.
The property is quite narrow and therefore required careful planning to optimise northerly aspects to rooms without visually crowding the additions to the boundary. Partially building to the southern boundary allowed the extra space to the north.
The kitchen, dining ,laundry and bathroom are contained in a lower roofed area which provides the link to the existing dwelling. This maintains a visual integrity for the existing section of the development and leads to the higher skillion roof of the casual lliving.



While we had a clear picture of what we wanted we were delighted with the innovative and environmentally friendly concept that Warwick developed for us.
