Custom home construction in the Las Vegas valley starts at a base range of $400 to $600 per square foot at the luxury tier. From there, price scales up based on lot complexity, structural elements (basements, cantilevered volumes, extensive site work), material palette, and design scope. Trophy-tier hillside homes in MacDonald Highlands, Ascaya or The Ridges commonly move well above the base range. Price per square foot is not a total budget. The final cost of any custom home depends on the specific lot, the design scope, and the decisions made throughout the process. Kingdom & Co. develops informed pricing during the design phase, after lot conditions and scope are established.
