Winning Design

David Barr Architects - 1/2/3/4/5 Cohousing

The Verdict

The winning entry from Fremantle-based David Barr Architects is a four-storey, modular design apartment building, featuring innovative approaches to construction and sustainability and a strong focus on flexibility and liveability.

The project introduces two firsts for Western Australia – using a prefabricated ‘passive haus’ construction system, which will reduce build time and cost, and delivering the first apartment building in the State with an average9-star NatHERS rating.

Selection & Judging

The winning design was selected by a panel of industry experts following a rigourous three-stage judging process.

A total of 47 entries were honed to a shortlist of seven to progress to Stage Two, before four finalists were ultimately chosen to progress to Stage Three. David Barr Architects was announced as the winner of the competition on June 29, 2017.

Key Points

AFFORDABLE DESIGNS
The winning design delivers a cost-effective build process, but also addresses the ongoing cost of living in the home through sustainability measures and shared facilities.

DESIGN QUALITY
Featuring an active edge, with integrated planter boxes on balconies and gold-finned window frames, a roof garden and shaded back verandah, the design offers a balance of privacy and community and will deliver an attractive, landmark development.

SUSTAINABILITY
The project will be Western Australia’s first apartment building to achieve an average 9-star NatHERS rating. It employs climate-responsive design and will be a Zero Energy building, meaning it will generate more energy than it consumes annually.

INNOVATION
The project will use a prefabricated ‘passive haus’ construction system, the first of its kind in Western Australia, which allows a rapid build process and significant savings on construction costs.

ENERGY EFFICIENCY
A PV system supported by 42kWh of energy storage will allow energy generated on-site to be used on-site, reducing peak demand by 30%.

WATER EFFICIENCY
A shared underground rainwater tank and above-code water efficiency measures are expected to reduce average water use by 60% and cut household water bills by up to $180 a year.

WASTE EFFICIENCY
Construction waste is dramatically reduced as a result of the prefabricated ‘passive haus’ system, and any waste created during the build will be recycled. The project includes space for green waste composting and a ‘swap space’ allowing residents to offer items they no longer need, but which may be useful to someone else.
