Sweden again: from one-off to product

In 2000, an orthopaedic engineer named Anders Solvarm was part-way through building a log home in western Sweden when he came across a book by Bengt Warne. He changed plans and built a glass shell over it. He and his family have lived inside it ever since — well over a decade of ordinary daily life in a naturhus, which is a rarer dataset than it sounds.

Making the second one easier than the first

In 2022 Solvarm and Niklas Dahlström founded Naturvillan and completed a flagship house, Atri, at Sikhall near Vänersborg. Wastewater runs through plant beds inside the greenhouse, where roots and soil biology take up the nutrients; what comes out is clean water and food.

The part that isn't about glass

The significant thing about Naturvillan isn't any single building. It's that they set out to make the naturhus repeatable — a design you can order rather than invent. That's the same gap we're working in, and the reason Warne's idea sat idle for thirty years wasn't physics. It was that nobody had made the second one easy.
