Indoor Playhouse / May 18, 2018 / Lundy Racine
The sixth step to build a playhouse is to sheath the walls with plywood or oriented strand board (OSB). The easiest way to do this is to attach the plywood while the walls are laying down on the subfloor. However it is critical you square the walls before applying and attaching the plywood. If you use cedar plywood it will need stain to protect it if you choose not to cover it with an exterior siding. Continue by standing the walls up on the subfloor and attach the walls together. Dont forget to attach a top plate to the top of the walls...this gives it strength to hold up the roof. Repeat for inside walls.
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.
