We’d lived in a totally recycled house for nearly 20 years and were very happy there- but it needed heating in winter and although we grew our own timber for firewood, we wanted a passive solar house that needed no extra heating. We also wanted to harvest our own water.

I researched and drew up plans for a semi-submerged,concrete tilt-up paneled house with a green roof. We wanted to be involved as much as possible with the building process; we worked with a friend who took on the title of builder for our project.

Three years later we have a beautiful, energy efficient house which runs on a minimal budget. Our home is light and bright and maximises thermal mass to keep us warm in winter.

All donations taken on the day will go to East Coast Alliance
