What started as a single person’s childhood love of treehouses has become a full-blown business, constructing custom tree homes, teaching treehouse workshops and selling supplies for do-it-yourselfers as well.

The Treehouse Workshop is a Seattle-based group of designers, builders and educators that has an impressively diverse portfolio of large and low-slung examples as well as high-and-daunting designs.

Their styles are likewise varied, ranging from traditional and whimsical to modern and functional, serving as temporary getaway cabins as well as full-time residences.

And it is not just about the desired function, but about the trees themselves – how much weight they can support, but also how they can be integrated into the design, becoming part of the structures they support physically and visually.
