A couple in Tulsa has two things in common: they are both expert gardeners and they both have Scottish heritage. They enlist Pete to build "something extraordinary" in their backyard by creating a treetop Scottish cottage 10-feet high in a robust pin oak. Pete creates this sturdy treetop gardeners' paradise to resist the powerful Oklahoma winds and connects it directly to the couple's home via a sky bridge: a first for Pete! The treehouse features custom hanging flower baskets, floral-themed decorative railings, interior cubbies for storing gardening tools, Scottish-themed furniture and even tartan curtains. When all is said and done, the treehouse will be a floating garden in the sky, built by Pete and the NTS crew while donning a new addition to their uniforms - authentic Scottish kilts.
