Outdoor Playhouse / May 17, 2018 / Gallia Cote
Decking and Sheathing Next comes the most rewarding part of the project: adding plywood panels to the roof (decking) and the walls (sheathing). For roof decking most playhouse plans call for 1/2" plywood panels that Ill simply nail down on to the rafters. Getting at the panels to nail them down might be a little tricky though. Some people suggest you go at them from inside the playhouse - with a step ladder poking up between the rafters. Then after each panel goes down Ill come down move my ladder and go back up for the next section.
After that its a matter of simply attaching the 2x6s together with galvanized nails. Ill want a smooth surface on the playhouse floor for my kids to walk on so that means laying down some plywood on the 2x6 floor joists. A couple 4x8 sheets of outdoor plywood should do the trick. Building the Playhouse Walls Building walls for a playhouse is pretty much the same method carpenters use to build a house. Using simple 2x4 studs Ill lay the boards out on the ground and create each wall as a separate unit. Then with some help from a friend Ill raise the completed walls vertically and nail the corners together... just like people used to do when building barns.
Building the Playhouse Floor After clearing and leveling a spot in the yard most playhouse plans have me dive into building the floor. 2x6 treated lumber arranged in a grid-like pattern (joists) seems to be the favored choice of materials for this part of the construction the same way its used in building floors for real houses. I can build the floor right on top of the spot I cleared in the yard but Ill probably put down a tarp first to keep the boards dry while I work on them. Building a floor thats square at each corner will take some careful measuring and maybe a carpenters square to make sure everything is lined up.
