Deck

A deck is an elevated, flat outdoor platform typically constructed from wood or composite lumber and attached to the rear or side of a house. Decks became a defining feature of American residential architecture in the mid-20th century, rising to prominence alongside the suburban backyard culture of the 1960s and 1970s. Unlike a patio, which sits at ground level, a deck is a raised structure supported by posts and beams, making it an ideal solution for homes with elevated first floors, sloped lots, or unstable soil conditions where a patio would be impractical. Contemporary deck design has been transformed by the advent of composite and PVC decking materials that offer the appearance of natural wood without the annual maintenance of staining, sealing, and replacing rotted boards. Modern decks often feature multi-level layouts, built-in seating and planters, cable or glass railing systems for unobstructed views, and integrated LED lighting. The structural framing beneath the deck can also be utilized with under-deck drainage systems that create dry storage or a covered patio space below. Building codes for decks are specific and detailed, governing everything from joist spacing and railing height to ledger board attachment and footing depth.
