Tree houses within reach 30 lofty cabins, playhouses, and getaways you can actually build

Diedricksen (Tiny Houses) highlights the versatility of tree houses in this enjoyable guide. Among the simplest structures are a narrow box with transparent plastic walls for bird watching and a "truck bed and cap held aloft on a tree stump," but it's the most complex edifices that make the biggest impression. These include a luxury Vermont tree house with a bathroom, loft bed, and back porch; an elevated pirate ship with a below-deck crawl space, a crow's nest, and tree limbs in the place of masts; and a "floating" yurt suspended by "an upgraded version of padded cargo straps." On the prescriptive side, Diedricksen walks through how to build an A-frame house, detailing how to set support posts in concrete, erect cross beams, and assemble the walls and ceiling. He also outlines general construction tips and principles, suggesting that maple, oak, and other hardwoods provide the most durable foundations and warning that "collaring" trees too tightly with decking or flooring restrains their ability to sway during storms and widen as they grow. The basic guidance won't be enough for novices to recreate the most dazzling edifices, but it will help get more modest projects off the ground. This will inspire readers to take to the trees. (May)
