The Williams Family Cabin

Tree-house designer Pete Nelson builds arboreal getaways that are large and ornate or small and simple in this series. Pete uses a combination of science and art to realize clients' sky-high aspirations of magnificent multi-bedroom treehouses with elaborate kitchens and bathrooms, or simpler, peaceful one-room escapes. Other backyard escapes featured in the series include a spa retreat, a brewery, and a honeymoon suite. "We awaken that inner child who dreams of living among the trees," Pete says.
