One of the most common questions we receive at Fratantoni Luxury Estates is, how long does it take to build a high end custom home? The honest answer is that there is no universal timeline for a fully custom luxury home. Every estate we design and build is entirely unique. Location, square footage, architectural style, level of detailing, engineering requirements, permitting jurisdiction, interior selections, and outdoor amenities all influence the total build time. A modern desert estate in Arizona will have a very different timeline than a French Chateau inspired residence with intricate stonework, hand carved millwork, and imported materials. A 6,000 square foot custom home is vastly different from a 20,000 square foot estate with guest houses, wine cellars, wellness suites, and resort style outdoor living. When building a high end custom home, timelines are determined by complexity, not averages. For most luxury custom homes, the full process from initial architectural design to final completion typically ranges from 18 to 36 months or more. Larger estates with extensive architectural detailing may extend beyond that range.
