This family home is set on a battle-axe block adjacent to a nature reserve above Balmoral Beach with panoramic waterviews and replaced an existing 2-3 storey house.

The battle-axe configuration of site and its orientation required the design to satisfy Council’s view sharing policy as well as maintain solar access to surrounding properties. These were the principle factors in the determination of the building form, which was further influenced by successful neighbour negotiations ensuring retention of existing views, solar access and privacy.

While the house is substantial, the battle-axe block allows it to be set well back with only a modest entry gate at the streetfront. At the other end, the extensive use of landscaping and terracing to work with existing ground levels allows the block to integrate with the adjacent nature reserve and ensure landscaping dominates the built form.

Sustainability

  • Application of good design principles and architectural solutions ensuring best outcome in response to site orientation and context
  • Compact footprint, working with existing ground levels to minimize excavation
  • Open plan layout and well positioned windows maximize natural cross ventilation, solar and natural light penetration
  • Use of sustainable/recyclable building materials throughout

Innovative sustainable design elements:

  • Low E glazing to improve thermal performance
  • 3KW photovoltaics to offset electricity consumption
  • 15,000L rainwater storage for irrigation, toilet flushing and pool top up
  • Concrete roof and floors to improve thermal mass
  • Well insulated external walls and roof
  • LED lighting throughout
  • Low energy and water consuming appliances and fixtures

Environmental footprint of the building is minimised by:

Open plan layout with carefully positioned openings ensure natural cross ventilation and natural light access to all parts, minimising dependence on artificial means for heating, cooling and lighting. Rainwater harvesting and low water consumption fittings minimises water use. LED light fittings minimise electricity use, further offset by use of photovoltaics.
