This gorgeous tree-top residence in Seattle tells a wonderful story of inventive architecture and repurposed and recycled materials. The Hale-Edmonds family took on the challenge of a steeply sloping site with flying colors, building a family-sized tree house for themselves and their twin girls. Perched on the side of a wooded area, the tri-level home features an open interior for family bonding, mingling with nature, and Mr. Hale’s affinity for DIY projects.
