Most luxury custom homes in the Las Vegas valley take 12 to 24+ months from groundbreaking to final walkthrough, depending on square footage, scope, finish complexity, structural detail, and material lead times. The White Gables Estate, a 6,024-square-foot traditional cottage with extensive custom trimwork, three concealed millwork doors, and slab shower walls, was completed in approximately 13 months. Kingdom & Co. develops a realistic schedule during pre-construction based on the specific scope and current material lead times — not a one-size-fits-all estimate.
