We love the idea of the Swedish TreeHotel, with its Almost Invisible Mirrored Tree House and its The Bird's Nest Tree House that Hides Among The Branches. The bird house designer, Bertil Harström of Inredningsgruppen, has another in the works: a UFO.
They describe it:
This is a boys dream: to climb aboard a spaceship has a huge appeal for people with fertile imagination. When working on The Nest, the idea came to create something completely contrary. Suddenly it became a magical UFO among the treetops. A composite exterior with classic round porthole windows hides a modern, comfortable living space with separate levels.
A tree-house that's a spaceship: surely an irresistible combination.
Indeed. More at the TreeHotel.
