Pallet Playhouse

Step 18 Floor, continued

The particleboard came from....what else? Pallets. I actually grabbed a bunch of them just for the 3/4 inch particleboard.  The underlying wood, the 2x4's and the 1x's weren't really up to par (they were oak and hard as granite), but I found a use for them here and there. 

The particleboard caused me some concern later when it began to rain. I thought they'd fall apart, but they actually held up well.

You can see the middle beam where the 2x4's meet really well in this picture. I toe-nailed all the 2x lumber to the 4x4's, every two feet or so.  This is important-- I may want to move the whole structure at a later date.
