Riddel Architecture have designed the three-storey sustainable house in Brisbane, Australia.
Called Hill End Ecohouse, the design of this three-storey Ecohouse relates to the subtropical Australian climate with openings maximised to capture cool breezes, sun and daylight. The house is in two halves, connected by the striking Gallery breezeway, which acts as a funnel for fresh air. Throughout, large windows provide views of the surrounding river landscape whilst reducing the need for artificial light. An informal and relaxed lifestyle is encouraged by the open plan layout and the timber and tin aesthetic conveys a sense of the Queensland character.
This Ecohouse is a new residence in inner Brisbane on a narrow riverfront site. The client’s brief for a sustainable home was enthusiastically followed with the resulting design aiming to maximise northern solar access, corrections to the edible gardens and flexible internal spaces for a range of occupation. Passive heating and cooling is achieved through thermal mass, appropriately designed sunshaping, insulation, ventilated wall and roof cavities and cross-ventilation to rooms. Construction materials maximise energy and water consumption and maintenance. Water will be collected and recycled on site, ideally removing dependence on town water supply and energy consumed in the house will be offset by grid-connected solar panels. The design process has been checked against the BCC Sustainable Housing Checklist and has achieved a 6 star energy rating.
The Hill End Ecohouse is fully self sufficient in both water and power and has a monitoring system to measure the use of energy, gas and water as well as temperature and humidity. This system also provides a carbon footprint for the house. The north-facing roof has 3kW photovoltaic panels which generate 15kWh/day, ample energy for household requirements.
