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.
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.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. Ahead, all the information you’ll need before purchasing materials for the project-or opting to hire a pro. A floating deck isn’t all that difficult to build for the DIYer with basic carpenter hand and power tools and a working knowledge of standard deck construction. Yet a traditional deck isn’t always feasible or permitted by local authorities, so for many homeowners, a “floating” deck-a raised wooden platform that sits a few inches off the ground-is the perfect solution. Summer isn’t summer unless you’re soaking up the sun, grilling, and chilling in your own backyard.
