The most difficult part of building a deck may be planning and designing the project. You've decided that it's a deck and not a patio you want to build and that you want to use real wood or synthetic decking. But determining where the deck should go, how large it should be, whether it should connect to the house or be free-standing are all important considerations before jumping into the project. The free or low-cost deck plans we have researched and assembled will hopefully serve as a springboard, helping you to define what you want and where to go from there.

    What: A wood deck built over an existing concrete slab or patio.

    A plain concrete slab in your backyard can be an eyesore, especially if it's cracked, is in a weird location or doesn't tie-in with the rest of the yard. One of the easiest and results-oriented ways to deal with that unsightly slab is to build a deck on top. The concrete is a solid raised foundation upon which to build a beautiful redwood deck.

    In a nutshell, the deck-over-concrete project includes two basic steps:

    • Attach construction heart or deck heart redwood 2 x 4-foot sleepers to the concrete slab.
    • Nail 2 x 4-foot or 2 x 6-foot construction heart or deck heart decking to the sleepers.
