The first universally-accessible treehouse in a public space in California was opened April 10, 2005 at Wilson Park in Torrance, California. The treehouse, a 2,500 square foot wooden structure, was designed to give children and adults of all ages and physical abilities an awe-inspiring experience — and a bird’s eye view. Created as a service to the immediate community and as an inspiration for others, nearly 30 treehouses have been built nationally.
