The design and size of your deck can also affect its cost. A simple, single-level deck will be less expensive than a multi-level or wraparound deck. Additionally, larger decks will cost more than smaller ones due to the increased amount of materials and labor required.

Custom designs and unique features like built-in seating, lighting, or built-in planters can also increase the cost. It's crucial to consider your budget and prioritize the features you want in your deck.
