Treehotel is a project developed by Swedish couple Britta Jonsson-Lindvall and Kent Lindvall, and it consists of 7 room-sized dwellings nestled deep in one of Sweden's many forests. Each room (one of which, the Mirrorcube, we profiled a few months ago) was designed by a different Swedish architect. Ranging from The Bird's Nest, with its mass of twisted branches, to The Blue Cone, which appears to be built entirely out of Lego, each house is attached to a tree not by screws and nails, but via a metal clamp.The rooms vary in size from 15 to 30 square meters. They're all constructed from wood and glass and feature an electric floor heating system, state-of-the-art incineration toilets and a water-efficient hand basins.
