New House Construction Cost Calculator
See exactly where your new-build budget goes — a trade-by-trade cost breakdown, not just a single cost-per-square-foot number.
Why a Single Cost-Per-Square-Foot Number Isn't Enough
Most online construction cost calculators give you one number: cost per square foot times your home's size. That number is a starting point, not a budget.
A real new-house construction cost calculation breaks the project into its component trades — site work, foundation, framing, roofing, MEP, and finishes — because that's the only way to see where a $50-per-square-foot swing in finish level actually shows up, and the only format a lender, bank, or GC can actually work with.
We prepare this as a full line-item estimate, not an automated online calculator, because your plans, your lot, and your finish selections are the only inputs that produce an accurate number.
What Goes Into Your Line-Item Calculation
Site Work & Foundation
Clearing, grading, and foundation type based on your lot's soil and flood zone.
Structure & Envelope
Framing or CBS walls, roofing, windows, and doors sized to wind-load requirements.
MEP Systems
Electrical, plumbing, and HVAC roughed in and priced by CSI division.
Interior Finishes
Drywall, flooring, cabinetry, and trim priced to your selected finish tier.
Labor by Trade
Regional Florida labor rates applied per trade, not a blended average.
Permits & Soft Costs
County impact fees and permit costs noted separately from hard construction cost.

Frequently Asked Questions
Is this an automated online calculator?
No. It's a professionally prepared, line-item estimate based on your actual plans, delivered by our estimating team — more accurate than an automated square-footage calculator.
What information do you need to calculate my cost?
Architectural plans or a detailed scope description, target finish level, and your build location so we can apply the correct regional pricing.
Can this be used for a construction loan?
Yes, lenders commonly request a line-item cost breakdown like this as part of construction loan documentation.
Does the calculation include land cost?
No, this calculates hard construction costs by trade. Land, financing costs, and impact fees are noted separately since they vary by parcel and jurisdiction.
How fast can I get my cost breakdown?
