The cost of building a patio can vary widely based on size and materials. Typically, you can expect to pay between $5 and $35 per square foot for installation. This range reflects different options, from basic gravel or concrete to more elaborate stone or tile designs.
For example, a standard 10'x20' patio (200 square feet) usually costs between $1,000 and $7,000. If you're considering a larger 20'x20' patio (400 square feet), the average cost ranges from $2,000 to $14,000. Actual costs may vary based on your choices and local labor rates, so it's wise to get quotes from multiple contractors.
