Woah. Sustainable Houses is a broad statement and a word which is so often overused. All of the houses we feature on Lunchbox Architect incorporate some aspects of sustainability — a water tank, a shiny array of solar panels, or a passive solar design because everyone should be making an effort. But there are some homes which take it even further and these are the homes that we're happy to stamp as sustainable houses.

It's virtually impossible to be truly sustainable, but some of the homes we feature use only renewable energy, sustainable building materials and capture and treat all their water on-site, making them self-sufficient. If we see a home that goes above and beyond in the world of sustainability, we'll list it here so that you can be inspired by their ideas and strategies.
