Fine homes built to
withstand generations.
A custom home builder and general contractor earning your trust through superior workmanship across the Lakes Region and White Mountains.

A Craftsman Who Still Swings the Hammer
Mackenzie Fleming has been building things since he was a kid. Starting in landscaping at 16, his passion for transforming properties led him to study construction at Wentworth Institute of Technology in Boston.
With more than 20 years of combined experience and a decade focused on completing custom homes across Northern New Hampshire, Mackenzie brings hands-on management from inception to completion. We don't just oversee the work from an office — we're on the ground, making sure every joint is tight and every detail is right.
New England summers are short, and projects need to move efficiently. We run our own excavation equipment, allowing us to take your project seamlessly from raw land to finished home under one roof. Clear communication, shorter project duration, and uncompromising quality.
From Raw Land to Finished Home
We offer comprehensive residential construction services throughout Northern New Hampshire. Having vertical capability means fewer delays, tighter quality control, and a single point of contact for your entire build.

Words From Our Homeowners
"Top-notch carpenters who were able to see the potential in our renovation. We were astounded by their beautiful craftsmanship and attention to detail. Every step of the way they were in constant communication about the project. We would not hesitate to hire them again."
— Carter J.
"Hi Mackenzie, we were up this weekend and I want to let you know how great everything looks! The workmanship and attention to detail is exceptional—especially the condition you left the parking area and grounds. Thank you!"
— Carlo P.
"My wife and I used the Catalpa crew for various renovations in our home. I would highly recommend them. First, Mack is a true craftsman. He holds himself and his crew to the highest standards. Their work is impeccable. For instance, for a post they created on our stairway, they made the joints so perfect it looks like one solid piece of wood rather than four pieces joined together. Second, Mack is a nice and decent guy. He truly wants his customers to be 100% happy with his work..."

Building in Northern New Hampshire
Catalpa Carpentry is a custom home builder and general contractor based in Holderness, serving the Lakes Region and the White Mountains. We know what it takes to build here — deep frost, heavy snow loads, lakeside setbacks, and steep wooded lots — because this is where we live and work.
Squam Lake & Holderness
Our home base. Waterfront cottages, year-round lake houses, and renovations on Squam and Little Squam — including the shoreland site work and setbacks lakeside lots demand.
Plymouth & the Baker River Valley
Custom homes and additions in Plymouth, Rumney, Campton, and Thornton — from village lots to hillside acreage that needs a long driveway and full site development.
The Lakes Region
Meredith, Center Harbor, Moultonborough, Laconia, and the Winnipesaukee towns. Kitchens, baths, and whole-home remodels — including camps becoming year-round homes.
The White Mountains
Lincoln, Woodstock, Waterville Valley, and over to North Conway. Mountain builds framed and roofed for serious snow loads, with schedules planned around mud season.
