The size and shape of the deck can significantly impact the cost. A larger deck will require more materials and labor, increasing the overall cost. Additionally, a complex design with multiple levels, curves, or angles can increase the cost due to the increased labor required.

For example, a simple deck with a rectangular shape and a single level may cost $20 to $30 per square foot, while a more complex design with multiple levels and angles may cost $40 to $60 per square foot.

Deck Materials

The type and quality of materials used can also impact the cost. Pressure-treated lumber, for example, is a cost-effective option but may not be as durable as composite materials. Cedar and redwood are popular options for decking, but they can be more expensive than pressure-treated lumber.

Additionally, the cost of materials can vary depending on the region and availability of materials. For example, a deck built in a region with a high demand for cedar may cost more than a deck built in a region with a lower demand.
