The DR T (Dwayne & Richard Treehouse) was made the summer before I left Missouri. In June I came up with the idea and ran it by Dwayne. He had long been thinking something similar and with that I forced the project forward. The final product contained an indoor living room that was closed off with a hinge-door and had a screened window facing sunset-west, an outdoor 2nd floor deck with bench, railing and table, and a 3rd story observation deck (to take the ladies) with a bench.
UPDATE: A year later it was upgraded to include a ground-level deck and a built-to-code staircase replaced the ladder.
