Simply one of these extraordinary sustainable treehouses would be amazing, but a whole network of interconnected treehouses Â is indescribable. Â Finca Bellavista is a community of tree dwellers living high in the foliage of the Costa Rican jungle. Community founders, Mateo and Erica Hogan discovered the 62-acrea property on the edge of the Rio Bellavista River with the intention of creating an escape for themselves. Upon brainstorming options for affording the property, they settled on building a treehouse structure and inviting friends and others to join them, the result is the interconnected treehouse community we've shared below. Each structure is connected by bridges and zip lines, which they liken to "the Ewok village in Return of the Jedi."
