Completed in Spring, 2004, Terunobu Fujimori, a professor of architecture at the University of Tokyo, built his boyhood dream hideaway in Takasugi-an (Chino, Nagano), a teahouse on stilts, in the bottom of his father’s garden.

The TreeHouse Workshop is a Seattle-based company that takes the art of constructing tree houses extremely seriously. They build an average of one tree house per month and hire extremely able builders and carpenters to construct their projects. Their finished works vary in luxury but some even include (counterintuitive!) fireplaces.
Designed in 1997 and finished in 2004, it took its creator Robert Harvey Oshatz 7 years to build entirely. This unusual tree house is situated in the forests of Portland, Oregon.
