Elevated playhouse for kids: posts and footings


Hi folks,

I'm going to be doing my first elevated playhouse in the backyard. 8x10' with the floor about 5 1/2 ft above ground.

I'm curious for peoples' experience with the posts and joists. I considered just making this a deck with framed walls added.

Would concrete piers, sunk to ground level, with the 4x4 posts in the pre-cast (4x4) slot on the pier's top be sufficient?

Also, joist size?

I will also be extending support off one of the ends to accommodate a beam for swings.

The "house" is just framed walls, window openings only, and a shingled roof (in Texas).

I know there are many ways to secure deck joists (scabs, slots, metal flanges) so I'll leave that for now.

Thanks in advance as always.

Those pier blocks won't secure the thing properly----they sink into the ground and do not have attachments--so the swing or even a heavy wind will cause the structure to rock.

I suggest you dig four post holes and embed steel fasteners into the concrete piers--

You are really just building a small elevated deck with a light structure on top-----check out the deck fastener section for ideas about post anchors----


2x6 floor joists will do----

Do you know you'll likely need a set of drawings and a permit for this?

Well...this is what I did for my kids.....except for the posts, it's all redwood....

Posts are pressure treated 4x4's....set 2' into the ground with concrete.

FYI, wood set below grade is a code violation although that is how things were all done in the not so distant past.

The current code requires that the wood posts are anchored to the top of the concrete pier which must be 4" higher than grade.

The new treated wood rots when buried===the earlier version was better--

I dot know about local codes except my HOA only requires application if it isn't attached to my house or garage and exceeds certain dimensions.

Will it resist rocking/swaying with the 4x4's anchored on top of piers like that?

If your piers are poured into post holes 2 feet deep or more---yep--nice and firm----for a temporary structure like yours---even burring the posts like Ddawg did would be fine---the kids will be grown and gone before the posts go bad---
