Indoor Playhouse / May 26, 2018 / Nicolette Sirois
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.
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.
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.
