Right here’s how the environment friendly 129-square-metres home got here to life, in simply 10 months.

Sustainability was a part of our preliminary transient after we approached Trias. We’re conscious that constructing generally is a wasteful course of and we had been eager to minimise our environmental affect as a lot as attainable — each by way of consideration of the design, supplies and thru funding in sustainable applied sciences.

We had been extremely fortunate to have the ability to work with essentially the most unimaginable architects, Trias and builder, Arc. They made the design and construct course of seamless and stress-free. We had no prior expertise of renovations or builds, and having watched a number of Grand Designs episodes, we anticipated the worst — working out of cash, huge delays and strained relationships.
