These two energy efficient houses on one block are the homes of a husband and wife (in their 70s) and of their son and his family of five.

Both houses are solar passive featuring the usual principles of such dwellings…orientation, insulation and ventilation. The houses are constructed of 100mm “green board”, have double glazing and PVC window frames.

House 2 has a polished concrete floor and other thermal mass features. As a result the houses are naturally warm in winter, cool in summer and require very little supplementary heating and no artificial cooling.

The houses also feature extensive use of reclaimed building materials.
