In many areas, a floating deck that isn’t connected to your home and stays under 200 square feet and below 30 inches in height may not need a permit. These freestanding structures are often considered low-risk, which can simplify the building process. However, building codes vary greatly based on location. Before investing in any home improvement project, check with your local permitting office for deck-building guidelines.

There are approximately 5.33 board feet in a 2x4. You can use the board foot calculator in this article to easily find the answer. A 2x4 is 2 inches of thickness by 4 inches of width, so you need to find the length, with 8 feet being the most common. You’d use the calculator here to multiply 2 times 4 times 8, and then divide by 12, arriving at a total of 5.33 board feet. 

Composite decking requires a solid foundation, substructure, or subframe to ensure stability. This base is typically composed of posts, beams, joists, and footings. The frame's joists can be built from various materials like composite, plastic, timber, or metal, as long as the base can support the deck's weight without shifting. A professional deck builder might recommend installing the frame on a solid concrete base for added durability. The final design and materials for the substructure will depend on your budget, the type of deck, and environmental conditions.

Deck boards should be spaced no more than three-eighths of an inch apart. This is enough space to allow water and small debris to pass through without collecting on the surface, but not enough to create a tripping hazard. Certain materials, like pressure-treated wood, shrink over time, so they may need less space at installation.
