Evans Tree House in Hot Springs, Arkansas was designed by American firm Modus Studio as an interactive educational experience for children.
The treehouse is situated within The Evans Children's Adventure Garden, which is located in Garvan Woodland Gardens, a botanical garden in Ouachita Forest. Owned by the University of Arkansas, the nature park occupies a wooded peninsula that is surrounded by the Ouachita River. The treehouse creates a rich visual and tactile environment in an attempt to stimulate the mind and body and strengthen connections to the natural world. Modus Studio used steel and heat-treated pine to build the "alive and mysterious" treehouse that blends into the native pines and oaks of the forest. Dendrology – the scientific study of trees – influenced the building's programme and design. Featuring a sculptural profile, the treehouse is meant to be read as a dynamic form that changes shape as one moves around the site.
