Steampunk Tree House

The Steampunk Tree House was created in 2007 by Sean Orlando and more than 60 San Francisco artists in an effort to explore the relationship between people and our rapidly changing natural world. The 40-foot-tall structure is composed of steel, recycled wood and clockwork components, and it’s styled after Victorian architecture and the work of H.G. Wells and Jules Verne.
