Nelson is a master builder and author of several books about tree homes. He co-founded Tree House Workshop with companion Jake Jacob, and they’ve been building custom tree homes since 1997. Nelson and Jacob combine this reclaimed wood into Tree House Workshop projects, and they’re known as the go-to builders for groundbreaking arborial designs. Given their place in nature, many professional builders use reclaimed timber to construct tree homes. But you can even make use of the identical type of wooden you’ll use to build an everyday home.
