Introduction

In September 2006, we purchased an old 1950s house in Mosman Park, Western Australia. Our plan is to let the house during 2007, demolish it and build a new house during 2008, then move into the new house in 2009.

Our broad requirements are as follows:

• three bedrooms
• two bathrooms, one being an the master bedroom's en-suite.
• a study/home office.

We also want the house to

1. incorporate passive solar design
2. be energy-efficient
3. be water-wise
