Who builds new homes in Derry?
We do, along with a short list of other local custom builders and larger production companies. Who builds new homes in Derry, and which kind fits you? A production builder sells set plans on set lots. While a custom builder works from your land and your ideas, which is what we do. Ournew home construction page describes custom designs and builds, from the foundation to the final finishes.
Searching for new home construction Derry homeowners can trust? So ask to see finished work, and ask who’ll be on your site every week. In practice, custom means the house is designed around your lot, your family and your budget, not the other way around. We also build additions, garages and framing, so we know how every part of a house fits together. After more than 30 years in business, we’ve found that a job well done starts with a single team that stays committed from the initial consultation to the final walkthrough.
How much does it cost to build a new home?
It varies depending on the square footage, site and finishes, but national numbers can be a good starting point. The National Association of Home Builders 2024 survey found that construction costs averaged around $428,215 for a typical new single-family home, roughly 64 percent of the average sales price. That works out near $162 per square foot for an average 2,647-square-foot home. Those are national averages, so New Hampshire builds can vary greatly. The survey also found that the finished lot averaged around 13.7 percent of the sales price. Septic or sewer, a well and a driveway can vary a site's costs a lot, so be sure to price those in.
Here's where the construction money goes, according to the same survey:
Stage of construction | Share of construction cost |
Interior finishes | 24.1% |
Major system rough-ins (plumbing, electrical, HVAC) | 19.2% |
Framing | 16.6% |
Exterior finishes | 13.4% |
Foundation | 10.5% |
Site work | 7.6% |
Final steps (driveway, landscaping, cleanup) | 6.5% |
Other | 2.1% |
However, finishes are the swing factor. Cabinets, flooring and fixtures can move a budget more than anything else, so it is important to decide early on where you would like to splurge. We give free estimates with up-front pricing, explaining what's included with each line item.
How does building a custom home work from start to finish?
It runs in a clear order, so skipping steps costs money. Here's the usual path, which matches how our projects run:
Planning and design. You bring architectural plans, or we help you create them.
Permits and approvals. Plans, septic or sewer, driveway and local reviews all get settled before digging.
Site preparation. Clearing, grading and utilities prepare the lot.
Foundation and framing. The structure goes up, built to code.
Systems and exterior. Plumbing, electrical and HVAC go in, then roofing, siding, windows and doors.
Interior finishes. Insulation, drywall, trim, cabinets, flooring and paint.
Final inspections. The town signs off, and you walk the house with us.
Winter shapes the schedule in New Hampshire. Foundations and framing go more smoothly before hard frost, so your start date matters, and a late-summer permit can mean a spring start instead of a fall one.
However, Derry has specific steps on this path. The town's list of items that require a building permit includes new construction, new wells and septic systems, and electrical and plumbing work that must be permitted by New Hampshire licensed master tradespeople. Derry's Code Enforcement office also saysall new residential houses need a separate plan review through the Fire Prevention Bureau, and inspections need 24 hours' notice.
What is involved in managing a new home build?
Managing a build means running the schedule, the trades, the budget, the permits and the communication, all at once. It's a full-time job, which is the part owners underestimate. We offer full project management, overseeing every phase from design and permits through site prep, construction and final inspection.
Here's what that looks like day to day:
Scheduling trades so the foundation, framers, plumbers and electricians don't trip over each other
Tracking the budget against the quote, so you know where you stand
Handling permits and inspections and booking them in time
Checking quality at each stage before the next trade covers it up
Talking to you regularly, so nothing arrives as a surprise
Because the schedule and the budget are linked, a delay in one trade ripples through the rest, and good management catches it early. A whole house build and project management Derry owners can rely on comes down to that last point. One of our clients said, "You always know where you stand in the projects," and that's the standard we aim for.

Sean Ryan & Son does, and we can start wherever you are. Which builder near me handles a custom home from start to finish? Ask any builder these questions:
Do you design as well as build, or do I need an architect first?

How do changes work, and how are they priced?
Can I see homes you've built from the ground up?
If you already have architectural plans, we collaborate with you to build exactly what you want. If you don't, though, we can help you create them. Ourgeneral contractor page explains how we manage a project from planning to completion.
Who manages ground up home construction in Derry?
A general contractor does, and that's the role we play. Who manages ground up home construction in Derry? We do, as the builder and project manager in one. Custom home building Derry owners want usually involves a dozen trades, so someone has to coordinate them. That's the job. We also bring modern building practices so the home is energy-smart and built to last.
Some trades are regulated, too. In Derry, electrical and plumbing permits must be pulled by NH licensed master tradespeople, so licensed electricians and plumbers handle their own work while we manage the schedule around them.

Frequently asked questions
1. What does the process look like from first conversation to completion?
It starts with a free quote and up-front pricing. Then we settle the design, either from your plans or with our help, and handle the permits. After that comes site prep, construction and finish work, and the project ends with the final inspection. We manage every phase, so you have one team to talk to from start to finish.
2. Can we see homes you have built from the ground up?
Yes, start with our gallery, which includes new home construction projects. We're happy to talk through what we've built and share photos and references. Seeing finished work is the best way to judge a builder, so please ask, because photos and references say more than any brochure. If you'd like to visit a completed home, tell us, and we'll see what we can arrange.
3. Do you manage the whole build including all trades?
Yes. We offer full project management and oversee every phase of the build. Electrical and plumbing must be done by New Hampshire licensed masters, so those professionals handle their own work while we coordinate the schedule and the quality checks. You get one point of contact instead of a dozen, so questions don't get lost between trades.
4. How are costs structured and how are variations handled?
You get a free quote with up-front pricing, and we explain what's included before work begins. If you want a change after that, we put it in writing with the price before we do it, so there are no surprises on the final bill. We'd rather talk through a variation early than argue about it later.
5. Do you work on our land, or help find a site?
Most of our builds start on the owner's land. If you're still looking for a lot, talk to us before you buy, because a site's septic, driveway, wetlands and soil can change the budget a lot. We'll tell you honestly what a lot is likely to need before you commit.
