From the NY Times, an unmilled tree can hold 50% more weight than the largest piece of lumber milled from the same tree. The more whole wood is used in place of steel, the less carbon is pumped into the air. By peeling smaller weed trees out of a crowded forest stand, the remaining trees get bigger and healthier. The small diameter trees are useful for rafters and framing. The large trees that were downed by wind or disease make for excellent columns and beams. This low cost, energy efficient structure is from the vision of World Tree Architecture and Construction. Whole Trees can keep construction costs as low as $100 per square foot. There is much to admire about this fantastically, brilliant idea.
This energy efficient building gets the inherent energy benefits of the unmilled wood along with solar panel technology.
