Designed and built by Oakland–based O2 Treehouse, the Pinecone is a five-and-a-half-ton geodesic home that can be installed in the forest or in your own backyard. The treehouse, accessed via a wood ladder and a trap door, is constructed from steel, wood, and glass that integrates into the forest canopy. Inside, 64 diamond-shaped windows provide 360-degree views of the surrounding forest or landscape. Even the floors are composed of transparent panels—enhancing the sensation of floating above the earth.
The Gouter Refuge is located at 12,582 feet in elevation (about 3,280 feet below the summit of Mont Blanc) along the Gouter route. The four-story, rounded structure juts out over a 4,921-foot drop, and it's the last stop before the final climb to the summit of Mont Blanc. Commissioned by the French Alpine Club and designed by Swiss architect Hervé Dessimoz, the wooden structure is clad in stainless steel and took five years to design and three years to build.
