According to a 2017 HomeAdvisor research, the average building cost per square foot is $150. Consider that the typical new home in the United States is 2,687 square feet. According to HomeAdvsior's calculations, rebuilding such home would cost around $400,000 USD. However, costs vary depending on many factors such as location and quality of materials used. In general, the total cost of a house depends on its size, its construction method, and its location. The largest factor affecting the overall cost of a house is its size. Larger homes are typically more expensive than smaller ones of the same type (e.g., two-story houses cost more than one-story homes). Factors such as the site of the property and the quality of materials used affect the price of a house but do not change its size. For example, a house built on a good site with high-quality materials is likely to be less expensive than one built on a poor site with low-quality materials. The average cost of a house varies by region. The most expensive way to build a house in America is in California where the average cost is $375,000. By contrast, the least expensive way to build in America is in South Dakota where the average cost is $76,000.
