Out on a limb

Tree houses not only capture our imaginations, they bring us close to nature. From platforms in anti-logging campaigns to carbon-neutral homes, we take a look at the role of tree houses around the world in the environmental movement.


Around the world there are many people living in tree houses. Pictured here is the El Castillo tree house which is part of an entire tree house community in Costa Rica called the Finca Bellavista, set in 350 acres of rainforest.

A few hundred years ago there were many tribes living in tree houses. This number has now dwindled to the point where tribes who maintain this tradition, such as the Korowai people of Indonesia, are extremely rare. These days tree houses are most commonly thought of as a playhouse for kids, but increasingly, they also serve as unique hotel rooms, retreats, studios, tea rooms and more recently, as homes. And they're not always small and cramped; they can in fact be luxurious mansions (the biggest tree house in the world is 10 stories high). Regardless of size, all tree houses are the natural result of inspiration for a creative structure that is in harmony with the environment.

A home for activists

While tree sitting has been used as a strategy in saving forests for decades, it has become more common in the last 15 years. In the 1990s, tree houses became a popular tool for environmental activists wanting to stall logging operations. Activists sometimes stay in trees for months at a time, so platforms are constructed to make the protest more comfortable. This practice sometimes extends to building tree house 'villages' where several tree houses are occupied and tied together. The Fall Creek/Red Cloud Thunder Tree Village in Oregon, USA consisted of seven tree houses complete with solar/wind power, composting toilets and even hydroponic sprout farms. It was occupied by an estimated 1,000 activists for almost six years, from February 1998 to November 2003, and as a result the Fall Creek forest still stands today.

One of the most famous tree sitters of all time is Julia 'Butterfly' Hill who occupied a Californian Redwood for 738 days. She lived on two platforms, 60 metres off the ground. Her vigil was extremely challenging with both wild weather and the anger of logging companies to contend with, but she generated a huge amount of publicity and was inducted into the Ecology Hall of Fame. After two long years a deal was struck and the 1000-year-old redwood was spared.

The Styx Valley in Tasmania has also been a well-known site for tree sitters. In November 2003 two platforms were raised into an old Styx gum nicknamed 'Gandalf' in hope that the old growth trees in the Styx Valley would be left alone by loggers. The protest spurred the imagination of architect Andrew Maynard who designed a tree house that would function particularly well as a protest shelter. The structure was designed to provide good shelter from harsh weather and spread its load over three trees, thereby protecting more trees with each dwelling. While these tree houses were not built, their design did help to raise awareness of Tasmanian environmental issues.

The simple life

Tree houses as homes lend themselves to a simple lifestyle, with fewer conveniences and a shared environment with nature and other living creatures. Around the world there are many people living this kind of lifestyle in the trees; in Costa Rica you will find an entire community of tree houses called Finca Bellavista - a sustainable rainforest community for the ecologically minded. If you can (or prefer to) survive without shopping malls, telephones and TV then you would likely be content with what you'd have instead; approximately 350 acres of rainforest encompassing an entire peninsula and a mountain, two white water rivers and a diverse range of wildlife.

Created for the sole purpose of preserving the local rainforest it resides on, Finca Bellavista is set up so that you can rent tree houses or buy plots of land and, if you choose to, build your own tree house and become part of the community. All electricity is generated on site via solar panels for the entire community so residents and visitors can still have a few modern conveniences (including internet access) while remaining carbon neutral. Each dwelling has a rainwater or springwater collection system and a biodigester to process food waste. Human waste is treated in an underground biodegrading septic system. Meanwhile, if you're still after that childhood fantasy that comes with living amongst the canopies, the community's 'Sky Trail' network of zip lines and platforms will have you yodelling like Tarzan in no time.
