Usually, this floating effect occurs on the two sides of the deck where the joists end. This, combined with the deck’s close proximity to the ground, gives the illusion of a hovering platform. The “floating” aspect is created when joists extend far enough past the blocks to obscure the blocks. If you’re unsure how to size your lumber, take a drawing of your deck to the engineering department of your local lumberyard (not a do-it-yourself center) for help choosing the correct dimensions. Lumber dimensions you choose depend on the intended size of the deck and joist span. You’ll set support beams on the deck blocks, and then install deck joists on top, perpendicular to the beams. Once the base is in place, you’ll apply standard deck construction techniques.

Deck blocks must sit on a stable surface, typically comprised of compacted sand a few inches deep, and their tops must be perfectly level. While you can build one on concrete pavers or over an existing level patio, perhaps the soundest way to support a floating deck is with pre-made concrete deck blocks that have notched tops designed to hold either 4×4 posts (on end) or 2×6, 2×8, or 2×10 lumber (on edge). If you decide that a floating deck is for you, keep in mind that your finished product will only be as good as its structurally sound base. If the ground beneath a floating deck settles, the deck could tilt or sag, requiring it to be rebuilt.A floating deck can become a hazard in serious storms, as high winds can potentially toss it off its base.Because floating decks sit low to the ground, there is an increased likelihood of weeds growing up between the decking planks.All of that said, don’t let the term fool you: You can’t take a floating deck with you if you choose to move-they’re not portable.Ī well-constructed floating deck adds style and comfort to a backyard, but it has a few possible downsides: If your neighborhood has a homeowner’s association, however, you will need to get permission before proceeding. Because it’s not attached to the ground or an existing structure, local building authorities do not require a building permit. They rely on a structural base that’s not permanently fixed in the ground, classifying them in most communities as personal property instead of real estate. Floating decks, on the other hand, sit low to the ground and actually appear to float on two or more sides, depending on the joist system design.A traditional deck has posts cemented below ground level, making the deck a permanent structure and subject to local building codes.Or for even more customization, choose the unfinished grey plywood and attach or apply your own surface layer for an unlimited range of design possibilities.There’s not a big cost differential in materials for either a traditional or a floating deck the main difference lies in their structural support systems. Choose from 4 standard deck choices: grey plywood, grey carpet, solid maple or solid oak. Each deck is made up of a rugged and durable galvanized metal frame and a removable deck insert.
