Building A Tree House
Decking
The decking of the treehouse is ¾” CDX glued and screwed to the joists. The exposed 3’ x 8’ decks have 5/4 x 6” pressure treated decking screwed and spaced 3/8” apart for drainage.
Wall and Roof Framing and Roofing
The treehouse walls are 2×4 and the rafters 2×6 reinforces with Simpson hurricane ties. We use a 2×8 pressure treated ridge because it extends out and over a deck. The idea here was to mound a pulley and rope to it later.
We flashed the top of the ridge beam with lead flashing.
For roofing we chose CertainTeed Carriage House Tile, Sherwood Forest color. These shingles had a scalloped shape and were a fun detail to add to the treehouse.
A Velux 30-1/16 in. x 37-7/8 skylight was added to one side for light and venting.
Wall Sheathing
For sheathing we used ½” T-111siding and oriented the lines horizontal to simulate a rustic clapboard or horizontal board look.
Windows and trim
We framed simple jambs and used 6 Bosco cellar window sash for the windows. The windows have a simple lock and two hinges each. 3M safety tape was applied to both sides in case of glass breakage.
Exterior trim boards are ¾” Cedar.
