The project was completed by David Bryce from Eco Solutions in Christchurch.

The purpose of this project was to upgrade some parts of the house while at the same time improving its overall sustainability, as measured under the Green Homes Scheme, to achieve as high a Star Rating as practical.

Rather than a rebuild, alterations were decided on as the most sustainable option.

These include:
Increasing insulation in the ceilings and walls and installing under floor insulation and double glazing
Adding a thermal mass section of floor, internal rock wall and thicker gib lining to increase passive heating
Converting a room to a solarium for food production and a source of passive solar hot air
Relocating and upgrading the kitchen to be more functional and energy efficient
Upgrading the wood burner and hot-water cylinder, adding a wetback heater and refining the existing solar water heater.
Refining cross-flow and passive stack ventilation and increasing natural lighting
Upgrading plumbing to utilise roof-water for non-potable purposes and to recycle grey water.

The alterations are designed to:
Reduce: condensation; electric power consumption and reliance; water consumption; smoke emissions; maintenance costs; internal toxins and waste.
Increase: food production; ventilation; comfort levels; natural lighting; safety and resistance to natural disasters; and use of sustainable products and materials.
All designers, contractors, manufacturers and suppliers were required to be conversant with sustainability principles, use appropriate techniques and processes and comply with an approved Environmental Management Plan. All products and materials were chosen as the most sustainable in the circumstances.

Emphasis was placed on proving a need for any work, minimisation of waste and re-use of any significant materials and features.
