The American studio Mithun has designed a 38-metre-high treehouse, which functions as a venue for the Jamboree of the Boy Scouts of America and as a treetop exhibition centre for people visiting West Virginia Park.
The Sustainability Treehouse was designed as a permanent home for the two-week-long Jamboree that takes place every four years and is attended by 50,000 scouts and volunteers.
The construction was designed to be self sufficient so it generates its own heating, electricity and water. In this regard have been installed photovoltaic panels and wind turbines on the roof, and a 4,500-liter cistern and water cleansing system that help reuse rainwater.
Aside from the annual scout Jamboree, the Sustainability Treehouse also hosts annual festivities and educational programs throughout the year. Moreover, the structure was recognized by the American Institute of Architects (AIA) as one of the ten top green projects of 2014.
