Fielding ADU Builders in New Hampshire
Fielding Adu Builders sales & service is the accessory dwelling unit and room-addition arm inside the Garrison Partners family, serving homeowners across New Hampshire who need more living space without leaving the neighborhood they already love. We handle garage conversions, backyard ADUs, and room additions with a level of discipline most Granite State homeowners have stopped hoping for: a written price before the first board is cut, a background-checked and uniformed crew, and a full year of written guarantee behind every build. The work is permitted, it is scheduled, and it finishes clean.
Why New Hampshire Homeowners Choose Fielding ADU Builders
Most of the homeowners we meet have already tried this once. They waited through a missed start date, watched the price drift upward at the door, or stood in a half-finished room wondering where the permits went. We built Fielding ADU Builders for exactly that person. Our 365-Day Done Right Promise puts the guarantee on paper for a full year: what it covers, how long it runs, and exactly how we fix it if something fails. If it is not done right, we come back and correct the defect at no charge. No fine print, no phone tag. And the price you approve on day one is the number on the final invoice, because we hand it to you in writing before any work begins. The crew on your property is background-checked and uniformed, and if you call at midnight, a live person answers. No voicemail, no callback queue.
We also know New Hampshire lots are not one-size-fits-all. Sloped yards, ledge, tight setbacks, older foundations. That is why we work with leading prefab and modular ADU platforms like Abodu, Cover, Dvele, Mighty Buildings, Boxabl, and Plant Prefab, alongside conventional builds using James Hardie siding and Tuff Shed-style structures. The right method matches your budget and your lot, not the other way around.
Backed by the Garrison Partners Family
Fielding ADU Builders carries The Garrison Standard on every job. Garrison Partners has been building to that standard since 2006, and the parent organization behind us is led by owners with military and first-responder backgrounds. The name is a promise: a garrison is the unit stationed to protect a place and keep it ready around the clock. We show up inside the window we gave, price the work in writing before it starts, build it by the book, and leave your site clean and squared away. Every addition and ADU we build is guaranteed in writing for a full year.
