Shades of green

The water, energy, materials and landscaping concepts used in this extensive restoration and addition to a heritage dwelling in St Kilda demonstrate a new approach to sustainable inner city living. It’s part of our Greener Kitchens & Bathrooms special.

Many common architectural elements are intentionally missing, including secondary finishes (such as paint) which have been minimised or eliminated completely by leaving durable construction materials in their natural ‘as built’ state. You won’t find white porcelain, plasterboard or chrome either; instead, toilets, basins and tapware are stainless steel.

Home to sustainable architect David Saunders and his family, the house is thermally efficient and all materials are either salvaged from the original house, recycled, plantation-grown, zero-VOC or naturally occurring. Their home is largely self-reliant with 43,400 litres of rainwater stored in 4 tanks, and energy use is minimal due to the incorporation of solar PV, energy efficient appliances and lighting and sensible lifestyle practices. They also grow fruit and vegetables in the courtyards and ‘roof farm’. Very little waste leaves the site due to careful recycling and extensive composting; grey water is diverted for reuse on gardens.

Stairs with flair

The humble staircase can do far more than provide access to your second floor. Stairs can fulfil multiple purposes from storage and thermal regulation to design feature or just sheer fun.
