We're getting more custom home inquiries now than in the previous three or four years combined.
It's every homeowner's dream to have your home exactly the way you want it – the right style, the right configurations of bedrooms and family space, the kitchen that works for your family, and so on, down to the little details that make your home uniquely you.
At this moment in time, the possibility of lower interest rates seems to have more homeowners itching to get rolling on a custom home, since lower rates will make construction loans, mortgages, and other financing tools less expensive.
The most common starting question, of course: How much does a custom home cost? Obviously it depends on location, size, complexity, material choices, and so on, but to offer ballpark numbers, these days we are generally seeing New England builders charge from $450-$750 per square foot. (Some high-end firms go even higher; unfinished square footage like basements can lower the number.) If you don't have your calculator handy, at those rates a 4,000 sq.ft. house would run $1.8M to $3M.
(Side note: Yes, that means that in most markets, your custom home will cost more to build than it could immediately be sold for.
"Our custom home...started with an extensive list of requirements and needs and GMT produced a design that far exceeded our expectations. GMT took the time to understand why we were making certain decisions and then found solutions that aligned perfectly with our vision, budget, and architectural consistency."
- GMT client Darin K., September 2025
The second common question: How long will my custom home project take? As with cost, there are a lot of variables here – your area's permitting process, lot preparation requirements, availability of materials and subcontractors, et cetera – but start with a ballpark timeline of
- 4-5 months for preconstruction work (which includes site survey, iterative schematic design, septic/sewer plan from civil engineer, buildable plans, permits and more.)
- and 8-14 months for construction.
If you're considering a custom home, here are some basics that will get you into the process, with some details on what to expect, and how to approach it to get the best version of the home you envision.
Five steps for getting started on your custom home
First: define your goals and needs.
This goes beyond how many beds and baths you need. What's important to you? How does your family use its living space? What would make your life easier, and what is "must have" versus "nice to have"? More details to help you plan here: Refining your home improvement goals.
Second: do some more dreaming; look at lots of examples.
Absolutely, find examples of ideas, designs, layouts and looks that you like.
They don't have to be a perfect match. Pulling together visual samples will help you communicate your ideas to potential designers, architects, and builders, and also do some filtering as you search for the companies that you want to work with.
You may find relevant examples in your neighborhood or town, or in builders' online portfolios including places like Houzz (here's our GMT page). See Where to find home design inspiration and ideas for more.
Next: learn a bit about the building process.
You don't need to be an expert in construction! But we always say, an informed client is a happy client. Knowing the stages that homebuilding projects go through will help you set expectations, ask useful questions, and minimize unnecessary delays or expenses.
We have lots of resources to help you with this.

Then: get a site consultation (or two).
As you get closer to being able to kick off your home build, and your lot is secured, we absolutely recommend a site consultation. Our clients have consistently told us this is the most valuable hour or 90 minutes in their entire building process.
It's a walkthrough of your lot, done together with your potential designer. This shouldn't just be a sales pitch to get your business. The designer should be a sounding board for your ideas, and bring some possible creative ideas to consider in making the home meet your goals (and fit your budget).
We strongly believe this should be part of your process in choosing your construction team. It's a get-to-know-you, a brainstorming/problem-solving session, and a chance to learn more about your home plans.
And ultimately: Choose building partners who listen well.
When it comes down to your final decision of construction partners, experience in designing and building custom homes clearly matters a great deal.
But also remember this:
Absolutely everybody in this industry says "We really listen to our clients!"
We say it too.
But some are better listeners than others. How can you tell who's really listening?
The site consultation(s) will give you some strong indications. Are they open to your ideas? Do they offer new ideas that really build off your input? Are they direct and clear about what's realistic and what's likely in or out of your intended budget? Do they suggest alternatives?
Don't stop there though. Check the references on your final candidates! (Ask them these questions to get specific, real answers.)
Choosing the right partners makes a huge difference. Good communication is an overlooked but critical part of getting the right results, and making the process more enjoyable and less stressful.
