Core 9

At 131sqm, CORE 9 is a compact and functional prototype sustainable house designed to challenge the way we think about sustainable living. The 9.1 star building won the 2018 BDAV Award for Residential New Projects $300,000 - $600,000 Construction Cost category. A gamechanger in green houses at a lower price-tag, the design shows how close together affordability and high environmentally sustainable design have come.
The project promotes harmony with the natural coastal surrounds, and addresses sustainability from construction to consumption of resources over the lifecycle of the home. The compact, cost-effective home sits comfortably within the site and actively benefits from passive solar principles and energy-efficiency and environmentally-conscious provision of recycled mass. CORE 9 aspires to support an industry change from legacy of poorly constructed and socially-isolated housing to become the pinnacle of sustainable design and people-orientated homes.
Design Matters Judging Panel
From the very beginning, we wanted to create something that changed the way people think about building a sustainable house. For most people, cost is the biggest barrier. We wanted to show that a highly sustainable house is affordable and it can lead to zero, or negative running costs.

Designed by Ashley Beaumont of Beaumont Concepts, CORE 9 is an affordable, attractive and functional house that downsizes the physical and carbon footprints of our homes and has been designed specifically for the Australian climate.

The contemporary, low maintenance three-bedroom layout can be adapted to any location with a construction scale allowing for energy ratings from 6 to 10-star to suit a range of budgets. CORE stands for the guiding principles of Carbon positive, Zero waste, Recycled, and Economic.


Combining passive solar design, operational energy efficiency and construction with locally sourced sustainable materials to minimise embodied carbon.


Work towards zero waste by adapting designs to use standard material lengths to minimise off cuts and select recycled or upcycled materials to avoid landfill contribution.


With the ability to be manufactured with recycled content to reduce raw material extract be recycled, up cycled or reprocessed after use.


Affordable for the Australian housing market balancing energy efficient design, optimal thermal performance and operational efficiencies.


Located in coastal Cape Paterson Victoria, the 456sqm site for CORE 9 features perfect northern orientation with rural views. The corner allotment is exposed on the east side to a road. The lack of any existing vegetation and no adjoining neighbours to the east or west provides little protection from weather exposure.

To keep construction costs as low as possible, standard construction methods were employed, but used in alternative ways where required. For example, the home employs an inverted roof truss allowing more light into the building, yet it doesn’t require any specialist construction methods or additional costs.

CORE 9 includes extensive shading structures, thermal double-glazed windows, a photovoltaic system and low maintenance zero carbon cladding. The feature timber shade device structure is constructed with sustainable Australian Silvertop Ash hardwood which left unstained continues to gracefully age and develop in colour to compliment the coastal location.

The eave and shading device of the northern façade of the home demonstrates the use of solar panels as a shading device to the living areas which provides considered balance to winter and summer solar gain.

Energy modelling indicates that the CORE 9’s operational costs could be as low as $0 a year which is a huge saving considering that the Victorian house running costs average $2000 – $3000 per annum according to the ABS.

The grand scale of glazing including Trend thermal doubleglazed argon filled windows and low-e glass used throughout the Cutlers encourages light and air flow of internal living areas to outside areas facilitating engagement in entertainment and social interaction.

The interior features upcycled, locally-made furniture, Eco Ply and Eco Blend concrete floors, LED lighting, locally manufactured low VOC paints and sealers, and an in-draw composting system in the kitchen. Reverse brick veneer walls with 100% salvaged red brick from a local demolition site features throughout which bring a rustic warmth to each room and also creates thermal mass to regulate internal or core temperatures.

A “Green Switch” is installed so on exit from the home everything can be easily turned off except the fridge to ensure minimum energy usage whilst the home is not occupied.
