The average cost of building a deck per square foot ranges from $20 to $50.
Let's assume the total deck cost is $4,000 and the total deck area is 200 ft2.
\[ DCSF = \frac{4000}{200} = 20 \text{\$/ft}^2 \]
The deck cost per square foot is $20/ft².
Let's assume the total deck cost is $7,500 and the total deck area is 250 ft2.
\[ DCSF = \frac{7500}{250} = 30 \text{\$/ft}^2 \]
The deck cost per square foot is $30/ft².
When choosing materials for a deck, consider durability, maintenance requirements, aesthetics, cost, and the climate of your area. Materials like composite decking offer long-term durability and low maintenance but may have a higher upfront cost compared to traditional wood decking, which requires more maintenance but has a natural look.
