A 3,000 to 4,000 square foot home typically takes eight to nine months once ground is broken. Homes in the 4,000 to 6,000 square foot range generally take about a year. Larger or highly detailed homes can run 14 to 16 months, and exceptionally complex projects with intense craftsmanship have taken three to five years. New builds usually take 30 to 40 percent longer than a comparable remodel, though a full top-to-bottom remodel on a large home can approach the same timeline.
