Major Cost Factors for Building a House in New Hampshire

Building a custom home involves both variable and fixed expenses. While your design choices account for most of the variability, other factors like permit fees and utility hookups are fairly consistent across the state. Below are some of the major costs categories to factor into your New Hampshire home building budget:

Land Acquisition

Land typically accounts for 10-25% of the total budget. Rural lots in New Hampshire span from around $50,000 to over $500,000 depending on the location, size, road access, terrain challenges, views, and other attributes. Plan ahead and research land prices in your preferred area before finalizing construction plans.

Construction Materials

The materials needed to frame, roof, side, insulate, and finish a New Hampshire home make up a significant portion of the budget. These include:

  • Lumber for framing
  • Concrete and rebar for the foundation & flatwork
  • Roofing materials
  • External siding
  • Insulation
  • Drywall
  • Flooring
  • Cabinetry & counters
  • Doors & windows
  • Hardware finishes -Paints and stains

For a higher-end custom home, materials often account for 50% of the total budget. Cost-saving design choices like using standard window sizes can help reduce this expense.


Given the complexity of home building, most people hire a general contractor to manage the construction crews and sub-contractors. In New Hampshire, labor typically accounts for 25-30% of the total budget. Using a general contractor generally tacks on an additional 10-25% to the price tag. You can save significantly on labor by acting as your own GC, but only if you have the knowledge and time needed to coordinate all phases of construction.

Permits, Fees, & Professional Services

Before breaking ground in New Hampshire, you need to obtain zoning permits, pay wastewater and utility fees, and hire specialized services like architects, engineers, and surveyors. These expenses often account for 5-10% of the total budget.

Financing Costs

In addition to the core construction costs, most builders finance a portion of the project cost through construction loans and mortgages. The interest incurred over the 6 to 12-month building phase contributes several thousand dollars to the final price tag.

Factors That Influence Building Costs in New Hampshire

While the per foot prices above provide a useful guideline, your specific build costs depend on many factors, including:

  • Location: Construction expenses tend to run higher in metro areas and popular vacation communities than in rural towns. Land costs also rise dramatically in high-demand markets.
  • Property attributes: Challenging sites with steep grades, poor access, or environmental issues boost costs. Conversely, open and flat building lots provide efficiency gains.
  • Materials selected: Using premium custom finishes like marble countertops, Brazilian wood floors and high-end appliances raises overall spend. Value engineering saves money.
  • House size and layout: Large and multi-level floor plans require more time, labor and materials to construct vs. simple one-story homes.
  • Level of customization: Personalizing a stock plan costs less than designing fully customized homes with architectural details.
  • Contractor used: Established general contractors charge 20% or more compared to managing home construction yourself. But they also simplify the process and prevent budget overruns.
  • Unpredictable expenses: Unexpected issues like subsurface rock, environmental remediation, HOA delays and weather damage all drive costs higher. Building contingencies helps cushion budgets.

If your dream home requires premium features or sits on a challenging lot, allocate extra cushion in your building budget.
