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."

    The image used in that article looks to be the same that was used in a similar article about houses made from shaped trees in Popular Science a few years back. It really is a neat concept as wood is a fairly good insulator. As long as you have a good water supply, good soil, and a community that is liberal enough to allow such structures, it looks like a good alternative to houses made from chemically treated wood.

          Oh, you might be able to do something that was standardized (? standardized trees), but you're likely going to get into some big problems 1) moving the things and 2) replanting them. Remember, one of the benefits touted is the ability to withstand major environmental insults such as water and earthquakes. The reason that trees (sometimes) do this is because of their extensive root systems. Said root systems are the product of many years of treeness.

          If you grown a structure, then dig it up, then put it back the root system is going to be fairly fragile for some relatively (in terms of the classical building trades) long time. It just doesn't strike me as very practical for very much. Perhaps some edge conditions or smaller things. You would need to combine this with some genetic engineering for really fast growth in order for this technology to be generally useful.

          And yet, at the point of harvesting, they can be used to build any structure you want, which is the fundamental problem with growing a house. Are you really certain you can predict - 20 or more years out - which cities will grow and which will not? It's fine for small things like park benches, but there are a lot of far simpler green construction methods for large structures.
        • Those trees might take 20+ years to grow, but that doesn't mean you decide what kind of house you want, design it and pick materials for it, and then plant some trees and wait the 20+ years. If you did, I suspect a great many fewer people would live in wooden houses.

It's much more important than height: hypothetically it might be possible to form cambium with a thin layer of wood into an appropriate shape, supply it with nutrients, and have a tree of any shape.

        Unfortunately, the hardwoods that happen to be good for support also happen to be the slower growers.

    • 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.
