This Colorado TREE HOUSE was designed by Green Line Architects and craftsmen at David Rasmussen Design who kept the words WHIMSY, ORGANIC, PLAYFUL and ARTISTIC at the forefront of their minds. Adding to the whimsy is the lack of right angles throughout the house. Most of the building materials are RECLAIMED and LOCAL, and the design highlights the beauty of the various woods used. We love the FLOATING STAIRCASE inside, ROUGH-SAWN CEDAR SIDING, logs used as door frames and fence posts, and ORGANIC MODERN front door. What are your favorite elements of the design? We can build this for you.
