With a little more effort, you can create some seriously impressive constructions that no one would ever guess started with the pallets behind your local grocery store. These projects can be a little more intensive because they usually require you to deconstruct the boards.
If you're up for the challenge, what about a pallet wood floor? While it's essentially going to be as difficult as installing any wood floor (plus the cost of sanding or staining your wood), you are getting your planks for (probably close to) free. If doing it yourself isn't your game, you can also work with a company that will install the recycled plank floors for you [source: Arctic Plank].
While you're taking apart your pallets, do consider that you can also easily panel walls with the slats or wood of the construction leftovers for a paneled den or nice alternative to wallpaper [source: Grand Design Co.].
In what might be the coolest and most useful idea, consider nailing together upright pallets to form easy decorative room dividers [source: Streu]. Less flimsy than a screen and much easier to customize with paint or designs, it's a great solution for those needing to divide a small space.
