How to Build a Deck: Framing & Construction
The process of framing a deck includes creating connections between joists, beams and support posts in order to build a code compliant deck structure. This in depth section will teach DIY builders to frame a deck, from installing a ledger board and frost footings to framing the perimeter of the deck.

Each deck design will naturally present its own order of assembly by which to proceed. Many builders take different approaches, but good planning will always result in a smoother building process. If you can highlight or number the individual forms on the plan, it may make it easier to select a place to start. Once pieces of the deck begin to materialize, it will give you a physical mass to attach to and square against. It is usually best to start against the house because the ledger board offers a stationary surface and length to pull measurements from and to attach joists to. If your deck will change elevations, it makes sense that you should finish one section before starting the next. Stairs and landings should be the final step in framing a deck.
