Building a twenty-by-twenty-foot deck (spanning four hundred square feet) typically costs between ten thousand and thirty thousand dollars total, depending heavily on material choices and professional labor rates. Standard pressure-treated pine keeps expenses on the lower end, while premium composite or exotic hardwood decking materials, multi-tier layouts, custom staircases, built-in bench seating, and complex structural railings push the final investment toward the higher end of the spectrum.
