- Walls: Hi-density concrete blocks with a thick layer of rockwool insulation on the outside, which is then civered with a waterproof membrane. "This acts like a storage heater because the concrete stays the same temperature all year round. RB"
- Roof: There are over 270 individual solar tiles on the roof instead of the more usual large panels. In the loft there is an 'inverter' which allows RB to sell any excess electricity he generates to the National Grid.
- Windows: Double glazed and filled with argon gas; they offer three times the insulation required by building regulations.
- Water: Two giant water tanks collect up to 2,000 litres of rainwater (grey water) from the gutters and downpipes. A pump takes it to the loft from where a pressure system delivers it to the loos for flushing and to the washing machine. Mains water is used for drinking, cooking and showers. A state-of-the-art hot water tank heats water in an instant.
- Sewage: A customised septic tank is buried in the garden.
- Conservatory: A two-storey glass conservatory runs along the front of the house, incorporating the living rooms with a spectacular 'minstrels' gallery' leading to bedrooms and bathrooms. It faces south allowing the sun to warm the air inside. The hot air rises by convection to the top of the house, leading to natural circulation of air. Two log burners help out in winter.
- Floor: The wooden floor sits on thick slabs of pink foam insulation.
- Ventilation: Extractors suck all the damp, warm air from the bathrooms and kitchen and pump it to a heat exchanger in the loft, which helps heat the house. "We achieve 72% heat recovery in the house; it is totally air-tight with no draughts. RB"
