9 Incredible Treehouses You Wish You Had As A Kid

"What I've found in raising four boys and building treehouses is that kids love big boxes as much as the gifts that come in big boxes," says landscape architect Keith Willig. "Meaning they like it simple and in a way that allows them to use their imagination. So we typically use recycled material, old fence boards, windows and doors." Surprisingly, it took two workers only three days to build this inventive structure. This is another project by Willig. "I like to interject a little midcentury-modern asymmetry into the design and then let the kids tell me what they want in the way of features — for example, a fireman’s pole, pirate flag, zip line, net, trap doors, et cetera." This multilevel treehouse took longer to build than the previous one, requiring about 10 days of labor by three workers. KWLA’s hope is that the buckets will serve as a small reminder of environmental consciousness and thoughtful water use.
