New Green Roof Homes “Sprouting” in Sydney


  • BRENDAN WONG REAL ESTATE REPORTER/inner west courier inner city

Three new terrace homes featuring green roofs covered with native plants that can grow in small amounts of soil with minimal water are going up in Newtown, Australia- a suburb located just 4 miles from the Sydney Central Business District.

Similar in concept to vertical gardens, the new green roofs will help provide thermal and acoustic insulation to three bedroom, two bathroom homes. Homes that also feature solar heating, a courtyard for added green space, and a lockup garage that can be converted into a fourth bedroom for car-free residents.

Architect and builder Oliver Steele says the idea behind the terraces is to build upscale dwellings that are energy efficient and have a low carbon footprint. “Everything from the foundations to the paint selection has been considered on an environmentally friendly basis. The concrete for the constructions is recycled. The windows are double glazed and low e-coated so they will be extremely energy efficient. The paints and interior finishes will be zero or low VOC so they’re not off-gassing, which is common in new houses. In terms of the design, we’ve used a lot of thermal mass and heavy insulation so the houses create their own comfortable year-round internal temperature independent of the fluctuations of summer and winter and without the need for air-conditioning.”

Natural ventilation was an important consideration in designing the homes. “There is an internal pond under the staircase and a retractable glass roof over the staircase which creates an internal atrium,” Mr. Steele says. “You get light coming down the middle of the house and any air that does warm up in summer will rise up out of the roof and draw in the cold air from the lower levels.”

The new homes will be ready for occupancy in April, 2015.
