After many renovations we’d always wanted to build a house from scratch. High on our priority list was sustainability, for a variety of reasons, but were not quite sure what that could/should entail!

Key to us was engaging local firms and, during this search, the idea of a house with good solar orientation was suggested and this soon developed into a full blown Passive House (still with the solar orientation, but now with awesome thermal properties and air tightness) was suggested and it quickly took hold as the ideal way to build our new house – given the climate, rising energy costs and achieving ‘comfortable’ living. When we’ve been living in the house for a year we’ll be able to gauge the impact on running costs, but we’re expecting to be pleasantly surprised.
