Live Architecture — Grow Your Own Home 106
Ostracus writes to share a new take on the word "treehouse." Engineers and plant scientists from Tel Aviv have taken the application of tree shaping to the next level, designing everything from streetlamps to houses. "A home built from trees, the researchers said, would be a natural storm protector. 'After earthquakes and after tsunamis the only structures that still survive are trees,' said Yaniv Naftaly, director of operations at Plantware, a company founded in 2002. Naftaly told LiveScience the same sturdiness should apply to tree-made homes. Eshel and TAU colleague Yoav Waisel are working with Plantware to commercialize the leafy designs. The team found that certain tree species grown aeroponically (in air instead of soil and water) have roots that don't harden. Once the malleable, so-called soft roots grow long enough in the lab, they are molded around metal frames in the shape of a playground or park bench."

Assuming you don't mind the wait for the shaped trees to grow the above sounds good, except I don't think the author thought about forest or even boring old house fires which can be more devastating than earthquakes or tsunamis which can easily be avoided if you pick the right place to live, unfortunately too many people don't. Wood burns when subject to enough heat and even treated wood which can be made fire resistant can give off poisonous fumes.

Not necessarily (Score:5, Interesting)
Not necessarily. Trees only grow by, well,growing new layers, outwards. That's why you can count the rings and all that. The old wood doesn't change shape or anything. (Though it might rot.) A lot of it in the centre is even dead already.
It's basically like living in a brick house where periodically you add a new layer of bricks to the outside walls. It eventually gets to be on hell of a bunker, but the rooms haven't changed at all.
If you prevent the inner surface from rotting, the rooms in the tree wouldn't grow too. Your walls would just get a little thicker each year.
Or I guess you could periodically shave a thin layer of wood from the inside, keeping the walls at a constant thickness, but having your rooms grow together with the tree. Frankly it isn't an unsolvable problem even then. Just put anything which needs pipes (kitchen sink, bathroom, etc) or wires (AC sockets, TV cable, etc) in the centre, so they don't need to be moved when you enlarge the rooms by 1mm.
But even that is probably over-thinking it, since it assumes an actual house in a tree. All these guys have done, is mould some soft roots into park benches and the like. And their houses, from what I understand, would basically be a layer of roots bent around some panels done out of something else.
Frankly, it's not that huge a progress. We've already known how to bend wood in any imaginable shape. See the curved Roman shield (scutum) for an example that's over 2000 years old.
I don't see many fundamental advantages in doing the same thing out of roots, as opposed to bending planks of wood. Especially since we're talking soft roots, as opposed to wooden ones. It's, almost by definition, a softer and less resistent material than wood.

Surely that's because of their shape and the leeway they have - being simply bendy poles. Once you shape them into buildings, you drastically increase their drag and reduce the leeway they have. It's not the fact that they are natural that makes them survive tsunami and earthquakes, it's their shape, so when you change their shape, you get rid of those beneficial properties.

Most trees have roots that are at or near the surface. As a result, if it rains hard enough to soften the ground, they blow over in storms that do little or no damage to houses. So, you would need to use trees that created taproots, which rules out most hardwoods. Also, given that trees tend to extend upward higher than most houses, any such "tree-house" would need a built-in lightning-rod system.
