For a custom home in Metro Atlanta's luxury market
Real-Life Scenario
The Project: A 4,500 sq ft custom home on a 0.8-acre lot in Suwanee, Gwinnett County. Five bedrooms, four and a half baths, three-car garage, unfinished basement, and outdoor living area.
The Budget: Land ($225,000), Architecture and Engineering ($75,000), Site Work ($65,000), Construction ($720,000), Selections and Finishes ($185,000), Landscaping ($75,000), Financing ($45,000), and Contingency ($100,000). Total: $1,490,000.
The Lesson: Construction was the largest line item, but the "hidden" costs of land, site work, selections, and contingency added nearly $700,000 beyond hard construction. Most first-time builders underestimate these categories.
