An above-ground pool with a deck can increase your home's value by as much as 4% to 7%, but it depends on your local climate, potential buyers, and the size and condition of your pool. Some buyers see a pool as a liability instead of a luxury, especially if it's at the end of its life span. In general, it's best to add a pool and deck to your property if it will bring you enjoyment—not because it raises the value of your home.

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.

When building an outdoor or deck gate, it's crucial to use durable wood that can withstand harsh weather conditions like sunlight, rain, wind, and snow. Redwood and cedar are excellent choices as they naturally resist decay. While redwood is considered more elegant, cedar is a more affordable option. Other suitable woods include oak and pressure-treated pine, which is specifically treated to resist rot. Although some softwoods like pine are popular, untreated softwoods such as pine and spruce should generally be avoided for outdoor projects because they are susceptible to damage from water, rot, and the sun. Ultimately, it's wise to consider your local climate when selecting the right wood for your gate.

Building a deck isn't too hard if you’re handy with carpentry, have the necessary tools, and are willing to put effort into it. However, other factors, such as plans, permits, and design, can be hard if you don’t have experience in those areas.

Note: You’ll need another person to help you build the deck (especially for framing and setting the beams). Building a deck yourself will be very difficult if you don’t have an extra set of hands to help.
