Vendor Inquiry
By Fred Loucks, CEO of Dunn & Stone Builders. Figures last reviewed September 2026.
Houston-area custom construction in 2026 runs about $180 per square foot with included features, $213 for a moderate set of selections, and $250 for a highly featured home. Land is extra. Enter living square footage and a finish tier to see a house-only range.
A 2,500 square foot custom home in this market typically costs $450,000 to $625,000 for the house only. I built this calculator from our actual prices on homes we built in Montgomery and Harris counties, not from a national multiplier.
Heated living area only. Do not include the garage or porch.
Kitchen and bath selections are usually what moves a house up a tier. The $250 tier also covers a very small footprint, which costs more per foot even when the finish list is not loaded.
Adds $20,000 to $30,000 as a separate band when the lot needs extra dirt, a longer drive, or other work above the base house price.
Adds $65,000 to $120,000 as a separate band when the lot falls toward water and may need pier-and-beam work.
For 2,500 square feet of living area, the house-only band is $450,000 to $625,000.
Turn a toggle on and that band appears beside the house number. The house-only range stays on screen either way.
The estimate is the house: foundation through finishes and builder fees. Land, design fees, permits, driveway, and landscaping sit outside it. The two toggles add only lot-prep or waterfront overage. They do not pull those excluded items back in.
For the full cost breakdown, see how much it costs to build a house.
A $100,000 construction budget does not reach a custom house in the Houston area. $300,000 is still below the 2,000 square foot included-features row. You can afford to build when the house-only range, plus land and site work, fits a budget you can finance or pay in cash.
These figures use the same per-foot band as the calculator. They do not include land. If you already own the lot, add site work from the toggles above. If the planning total is larger than what you can fund, drop the footprint or the finish level.
We have built over 1,000 homes in this market since 1999. I use this same range in the first conversation so a buyer who cannot reach it finds that out before design work starts.
The most recent NAHB Cost of Construction Survey (2024 data, published January 20, 2025) puts national construction at $428,215, or about $162 per square foot on a 2,647 square foot home. Local custom tiers sit above that national average because they are custom, not production.
This split is approximate. It is a planning sketch, not a line-item takeoff.
Land purchase stays outside the calculator. Lot-prep and waterfront overage appear only if those toggles are on. The house-only range is the structure, mechanicals, and finishes.
No. This Houston-area calculator returns a house-only estimate: foundation through finishes and builder fees. Land, permits, design fees, driveway, and landscaping sit outside that number.
In 2026, a custom home in the Greater Houston area typically costs about $180 to $250 per living square foot, not including land. Finish level and living size set where you land inside that band.
A 2,500 square foot custom home in the Houston area usually costs about $450,000 to $625,000 for the house only, before land or extra site work.
This calculator's range tracks current Houston-area contracts when living area and finish tier match the plan. Unusual lots, late design changes, and municipal extras move the final number. It is a planning range, not a bid. Replace it with a fixed contract after design and site work are settled.
The estimate includes the hard cost of the house: foundation, framing, roofing, mechanicals, insulation, drywall, finishes, windows, doors, fixtures, and builder fees. It excludes land, design fees, engineering, permits, landscaping, and the driveway. The optional toggles add only lot-prep overage of $20,000 to $30,000 or waterfront or slope work of $65,000 to $120,000. They do not add the excluded items.
A $100,000 construction budget does not reach a custom house in the Houston area. $300,000 is still below the 2,000 square foot included-features row. You can afford to build when the house-only range, plus land and site work, fits a budget you can finance or pay in cash.
Yes. The calculator is free and does not require an account or personal information to return an estimate.
Yes. Typical lot-prep overage in the Houston area is $20,000 to $30,000. A sloped waterfront lot that needs pier-and-beam construction can add $65,000 to $120,000. Use the toggles to add those bands.
