A 500 square foot Custom-tier casita in Las Vegas ranges from approximately $275,000 to $425,000, based on Custom-tier pricing of $550 to $850 per square foot. Custom-tier reflects higher-end natural stone products, brand-name appliances, custom cabinetry, and built-in features — the specification level Kingdom & Co. builds to. Actual pricing depends on lot conditions, utility routing, finish selections, and appliance package.
