Imagine growing a home from living trees instead of building a home from wood. Mitchell Joachim, at the MIT Media Lab's Smart Cities Group, along with ecological engineer Lara Greden and architect Javier Arbona, have proposed a system of homes that are actually a living ecosystem.
Joachim's vision is based on a gardening method known as pleaching, which involves weaving branches together to form living lattice(格子) walls. Since the growth patterns of trees are affected by wind and sunlight, it may be possible to manipulate the way a tree develops.
This idea is an extreme, yet simple and beautiful, form of green building. Not only does it not cause direct harm to the environment, but it is actually part of the environment. The house, which is a network of trees, would clean the air and also provide a home for animals and birds. Not only does it do zero damage, but it will hopefully clean the air, says Joachim.
A 100 percent treehouse would take years to create, Joachim said. Depending on the climate, a house could take anywhere from 5 to 30 years to grow. Fortunately, there's a way to speed up the process.
Ecological materials, Joachim suggests, should be included in the housing designs. For example, windows can be made from soy－based plastics that would flex (折曲) with the home as it grows.
So what happens when a home and the great outdoors are one and the same? A home would bee an actual ecosystem, a munity of plants, animals, and bacteria working together. The trees would also give off water vapor that would assist in cooling the homes. Solar panels and wind would help provide energy. Straw and clay could be used to insulate(使绝缘) the structures. The tree homes might even have soil pockets, where plants could grow from the structure itself.
Joachim's project is called MatScape, designing a house in California that will be constructed from 50% recycled and 50% living elements. He sees it as an experimental step toward the final living house.
