Step 2: Lay the Floor

Now attach 4×8 sheets of plywood or another sturdy sheet material to the pallet subfloor. You might also want to take the extra step to sheet both sides of the pallet floor structure and insulate it. This will give you a very strong and sealed base for your house. The thicker the plywood in the floor the better, especially the surface you walk on.

You’ll notice that the plywood overhangs the pallets a little. Just cut off the extra plywood. Be sure to save these small pieces though, you’ll most likely find a use for every piece of extra wood. I’ve been using screws to connect all the wood in the tiny free house simply because I think it’s stronger and the house is mounted on a trailer.

  1. last year the plywood floor in my metal storage rotted through, i found waterproof plywood 4×8 3/4 sheets at lowes that were cheaper than regular plywood. they have worked good so far. just a heads up on the flooring.

  2. Hi, this site is very informative thank you for taking the time to put it up.
    I was hoping to build a large cabin and frame the walls with pallets to save on timber costs.
    The question i have regarding laying pallet floors is,How long is a pallet floor expected to last since the wood used is untreated pine
    (in New Zealand anyway)

  3. I love this website.

    Depending on how long you intend to use this structure I would suggest using some kind of wood preservative on the pallets under the plywood floor. You’re not going to have access once it’s built.

    Use WBP plywood if you can (water and boil proof (Marine ply)) or as Bruce found out, it will quickly delaminate.

  4. There is a general piece of misinformation regarding Marine Plywood. And that is: Marine Grade Plywood contains no voids, That’s the only structural difference.. The entire sheet of any Marine Grade Ply has no “air holes or voids, small gaps” or imperfections”. which is commonly seen in most other plywood.. But the same “resins”, “fillers”, and cross-linking agents which hold together marine plys are essentially identical to the adhesives used in most any other exterior plywood. Additionally, the majority of marine grade sheet goods have a Mahogany veneer glued to their outer layers. It’s nice looking and finishes nicely but it’s much more expensive than other domestic wood veneers and unless it’s certified plantation grown, Mahogany is far from proper to use for a storage shed. If these projects are to be remain “green”; fully re-purposing materials which are hand-me-downs from the industrial world, Its my humble opinion any ply-woods used should be sheet-goods that have been rescued from projects of days gone by. Additionally, most any plywood you use for the floor will be fine as long as it’s been dried, screwed and nailed to the pallets below and then kept covered from any future water. Only then you can be rest-assured your efforts will not be in vain. In all, I have to sayl, I really enjoy reading these re-purposing articles and pouring over the latest ideas and concepts that have inspired exciting beginning solutions.
    Thank you,, everyone, for putting your hearts and souls into this
    creativity. I believe is the only antidote for waste and despair.
    Kudos!
