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.
The ninth step to build a playhouse is to install ceiling joists and rafters as per playhouse plans. Another option is pre-manufactured wood roof trusses. If you are using rafters instead of pre-manufactured wood trusses you will need to add a girder post to each rafter in the center to give it support. The tenth step to build a playhouse is to sheath the roof with plywood and decide upon a roof covering. Most plans will call for asphalt shingles or wood shingles but its up to you. Dont forget to apply felt before laying the shingles on the roof.
It is laid under the shingles and acts as a moisture barrier. The tenth and last step to build a playhouse is to install windows doors siding and trim paint and caulk everything as per playhouse plans. It is possible your playhouse plans will call for a dormer or two to fancy it up a bit. Those are easy and your playhouse plans will direct you how to install them. One last piece of advice for window installation is to use some type of safety glass to protect the children for when it breaks during play.
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.
