Hard cost ranges by finish level
Hard costs are the physical construction portion — materials, labor, subcontractors. They are the number builders quote per square foot, and they are not the number you will spend.
- Builder-grade custom: $300–$450/sq ft — production-grade finishes, standard ceiling heights, basic exterior detail.
- Mid-luxury custom: $450–$650/sq ft — site-built cabinetry, stone counters, designer plumbing, mixed siding.
- High-end custom: $650–$900/sq ft — full-service architecture, premium millwork, steel windows, integrated systems.
- Ultra-luxury: $900–$1,800+/sq ft — bespoke materials, large open spans, smart-home integration, complex sites.
What's missing from the per-square-foot number
Builders quote hard costs. Total project cost adds land, soft costs (design, permits, engineering, financing), site work, contingency, and furnishings.
- Land: 15–35% of total project cost in most markets.
- Soft costs: 8–15% of hard costs.
- Site work: $30K–$300K+, wildly variable.
- Contingency: 5–15% of hard costs.
- Furnishings, AV, landscape: often 5–10% of hard costs.
Regional cost reality
The same 3,500 sq ft house costs very differently in Austin, Bozeman, Greenville, and the Hamptons. Labor scarcity, code requirements, lot prep, and material logistics all swing the number.
