Treated 1/2" plywood floor with 2"x4" floor supports. How far apart do these need to be for a couple of less than 75 lbs. kids and would you lay your framing 2x4"s across the top of the posts (will be 4" high after burying in concrete 18 inches), or would you put the 2x4"s up on edge, lag screws holding them to the inside of the posts and run your floor 2x4"s on edge above them? Hope I didn"t make this real confusing. [Reply]   [No Email]

Not needed and will destroy your posts. Dump a pail full of rocks in the hole, get a good spud bar tamper and fill with the dirt that came out. The house will give them support. Use 2x4 girts, flat, between the posts above the floor joists. That way you have flush surface for siding and dead space for insulation before interior siding. Maybe pop for a set of plans for playhouse. Sounds like you could use them. Gordo Gordo   [Reply]   [No Email]

Small building project in reply to IHMANKY, 06-12-2009 18:21:01   Not completely clear on your plans, but playhouse needs to be high enough for an adult to stand up in it. Floor supports need to be standard 16 inches on center apart. 1/2 inch plywood is not really thick enough. 5/8 would do, 3/4 best. 2 x 4 floor joists on edge will be ok for that width. To support floor joists, run a 4 x 4 between the 4 x 4 posts, attached by galvanized lag bolts or nails put in at an angle, reason for galvanized bolts is that the treated lumber will rust uncoated nails, in fact use ganvanized nails every where you nail into treated lumber. You can drop the floor joists down on the 4 x 4 enough to make the 4 x 4 level with the flooring. Reason for putting 4 x 4s between posts is to have a flat surface to fasten outside siding to at the bottom. 2 x 4s edgewise up the wall to fasten siding to higher. I'm not clear if you intended siding, if not ignore this paragraph. The playhouse I built was 8 x 8 with a 4 foot porch. Hope this helps. KEH   [Reply]   [Send Email]
