How much do custom homes cost to build? In our part of New England, our three most recent custom homes, all completed in 2025, had budget bands from $800,000 to $3,000,000. The lot, the design and the finishes moved those budgets more than square footage alone. Here is the short version:
- Our recent custom homes: $800,000 (1,700 sq ft, Atkinson, NH), $1,000,000 (3,100 sq ft, Newton, NH) and $3,000,000 (5,000 sq ft, Andover, MA).
- Biggest cost drivers: the lot and site work, the complexity of the design, the finishes and appliances, and outdoor living features.
- Typical timeline: 8 to 16 months.
These are budget bands for real homes, not a quote for yours. Norman Builders has built and remodeled homes across the Merrimack Valley, the North Shore, the Seacoast and southern NH since 2007, and the examples below come from our own projects rather than national averages.
What Our Custom Homes Cost
| Project | Town | Completed | Size | Budget band |
|---|---|---|---|---|
| Custom lakeside cottage | Atkinson, NH | 2025 | 1,700 sq ft, 3 bed, 2.5 bath | $800,000 |
| White Cedar Way custom home | Newton, NH | 2025 | 3,100 sq ft, 4 bed, 2.5 bath | $1,000,000 |
| Golf course estate at Andover Country Club | Andover, MA | 2025 | 5,000 sq ft, 4 bed, 5 bath | $3,000,000 |
The Atkinson cottage sits on a waterfront lot. It has engineered board-and-batten siding, composite decking and trim, a screened porch over the water, large windows and glass doors facing the lake, a custom blue-painted kitchen and a primary bath with a pebble shower floor. Its exterior materials were chosen to hold up near the water with low maintenance.
White Cedar Way is a classic New England home in Newton, where we are based: James Hardie lap siding, PVC trim, black Andersen windows, an attached two-car garage, a covered front porch, an open-concept plan, a primary suite with walk-in closets and a high-performance building envelope.
The Andover Country Club estate sits on a golf-course lot. It has fiber cement siding with natural stone veneer, a mahogany front door, coffered and tray ceilings, wide-plank and herringbone white oak floors, Wolf appliances, a walk-in pantry, bluestone patios, a gunite pool, a covered outdoor living room with a stone fireplace and outdoor kitchen, and a three-car garage.
Size alone does not set the budget. The 1,700 sq ft cottage and the 3,100 sq ft White Cedar Way home had budget bands of $800,000 and $1,000,000, and the estate's lot, pool and outdoor living areas are part of its $3,000,000 band.
Factors Affecting Custom Home Building Costs
Location and the Lot
The lot often decides how much of the budget goes into the ground before the house starts. Questions that change the number: Does the lot have town water and sewer, or will it need a well and a septic system? How much clearing, grading and driveway is needed? Is it on the water, on a slope or on a golf course, where the design has to work around views and setbacks? In New Hampshire a septic design is approved by NHDES; in Massachusetts septic systems fall under the state's Title 5 rules, administered by the local board of health.
Design Choices
Simple rooflines and footprints cost less to frame and roof than multiple gables, porches and bump-outs. Interior details add up too: coffered and tray ceilings, built-ins and custom millwork all take labor. Our design-build process refines the concept, then defines the final building components, the structural, mechanical, electrical and plumbing systems, and the doors, windows and roofing, so those choices are priced before construction starts.
Materials and Finishes
Finishes are where custom homes spread apart. The same room can be built with very different cabinets, counters, tile and appliances. In our homes the range runs from quartz counters and luxury vinyl plank floors in the Atkinson cottage to inset maple cabinets, a walnut island and Wolf appliances in the Andover estate.
Labor and Trades
A custom home brings together framers, roofers, plumbers, electricians, HVAC installers, tile setters and finish carpenters. In a design-build arrangement one team manages them, with a project manager running the schedule and communicating with you regularly.
Permits and Approvals
Your town issues the building permit and inspects the work in stages, and permits can take from several weeks to months. Septic approvals, zoning questions or conservation rules near water can add time, and time on a construction loan has a cost.
How a Custom Home Budget Comes Together
Our design-build process starts with defining the budget: we discuss your number and develop an estimated project cost, including as much detail as possible. From there the steps are a conceptual design and floor plan, design development, and final plans and construction documents. Allowances (placeholder amounts for items you pick later, such as tile or light fixtures) let the budget move forward before every selection is made, so it pays to ask how each allowance was set.
Average Cost to Build a Custom Home
National averages mix very different markets, so they tell you little about building in Andover or Atkinson. If you are pricing a house in Massachusetts, our guides to the cost of building a house in Massachusetts and the cost per square foot to build a house in Massachusetts cover typical ranges. This post sticks to what our own custom homes cost and why.
Is It Cheaper to Build or Buy a House?
Usually buying is faster, and building gives you control over the plan, the materials and the energy performance. When you compare, put the land, the site work, design fees and the cost of living elsewhere during an 8 to 16 month build next to the purchase price of an existing home plus the work it would need. Our post on whether new construction homes are worth it covers the trade-offs in more detail.
Frequently Asked Questions about Custom Home Building Costs
How much does it cost to build a 2,000 sq ft house?
None of our published projects is a 2,000 sq ft new home, so we won't guess a figure. The nearest in size is our 1,700 sq ft lakeside cottage in Atkinson, NH, with an $800,000 budget band, on a waterfront lot. For Massachusetts per-square-foot ranges, see our guide to the cost per square foot to build a house in Massachusetts, and for a mid-size house, our guide to the cost to build a 2,500 sq ft house in Massachusetts.
How long does it take to build a custom home?
Our custom home timeline guide puts a typical build at 8 to 16 months. The biggest variables are how complex the design is, the weather and how long your town takes to issue permits, which can run from several weeks to months. Refining the design itself often takes a few months.
