World's Most Unusual Hotels
Treehotel, Harads, Sweden
Childhood treehouses never looked like this. Leading Swedish architects give the backyard staple a strange futuristic makeover at the Treehotel (completed in 2010, it was inspired by a film about three men who rediscover their roots by building a treehouse). Each treetop suite has its own look, whether resembling a bird’s nest or a flying saucer, or seemingly constructed entirely from Lego blocks. The most ingenious appears constructed from nothing at all: the mirrored exterior reflects the forest on all sides—as if creating a gap in the space-time continuum.
