Custom home construction costs $225-$450+ per square foot excluding land. A 2,500 sq ft home runs $562,000-$1,125,000 for construction. Add $150,000-$1,000,000+ for the lot depending on location.
12-18 months from design start to move-in for standard custom homes. Complex or premium builds take 18-24+ months. The design and permit phase alone takes 5-10 months.
