Nestled among the eucalypts, the house takes full advantage of magnificent lake views

with all living and bedroom areas opening on to the garden with large glass doors so that the indoors and outdoors seamlessly integrate. The client brief included a passive solar, low maintenance rural residence with an industrial aesthetic located for a beautiful site with northern views to Lake Pambula.

Central to the philosophy of the project were life cycle costs and the client accepted that higher initial costs would be offset by minimising running costs over the life of the building. The need for air conditioning has been eliminated and the need for mechanical heating has been drastically reduced through the use of northern orientation, high levels of thermal mass found in the concrete slab and precast concrete walls, high levels of insulation including sandwich panel external walls, maintaining thermal breaks between all internal and external construction, insulated edges to the floor slab and calculated levels of glazing achieving optimal levels of light and thermal comfort.

Building envelope materials

  • Floor: Earth coupled, exposed burnished concrete slab 200mm thick, with 50mm perimeter and edge insulation
  • Walls: precast concrete sandwich panels, R3.9
  • Roof: timber framed, steel corrugated roofing, plasterboard ceiling
  • Glazing: Double glazing, uPVC frames U4.3, SHGC 0.6;
  • Insulation: XPS to floor and walls; R6.0 fibreglass for ceiling/roof construction
  • Sealing, air tightness: all floor/wall/ceiling joints, windows and doors are mastic sealed, all exhaust fans with auto-baffles: typical 3-5 AC/hr


  • Electricity: 6kW 20 panel PV, grid connected
  • Gas: LPG to auxiliary gas fireplace heater and gas cooktop
  • Sewer: dual black and grey water pipe provision for possible grey water recycling
  • Water: regulation 4000L rain water tank
  • Hot water: heat pump electric
  • HVAC, heating/cooling: ceiling fans to Main Bedroom and Dining Room; in slab electric heating to wet areas, Kitchen and Study; fresh air vent to fridge condenser coil
  • Lighting: all LED

Entertaining in our new home is a sheer delight. Whether we are catering for large parties, alfresco lunches or dinner with family and friends, the layout is highly successful. The outside fire means that even in the middle of winter we can entertain on the deck, enjoying the evening ambience and the twinkling Merimbula lights across the lake. For times when we are by ourselves the house is intimate, as the guest wing does not intrude on the main part of the house. The study is perfect for a quiet read or computer work and because family living is in one room, we always feel closely connected.
