What we build

Residential Construction Services in Massachusetts

From one room to an entire house, every Northline project runs on the same process: honest planning, a written scope and careful construction.

Home Additions

More room without leaving the neighborhood you love — designed to look like it was always part of the house.

Kitchens that work for weeknights and holidays alike, detailed with white oak, stone and honest hardware.

Primary suites, family baths and powder rooms built with waterproofing and ventilation done properly.

Comprehensive renovations that reset a home's layout, systems and envelope in one coordinated project.

New homes rooted in New England form — durable envelopes, honest materials, quiet detailing.

Siding, windows, roofs, porches and entries built to handle coastal wind, snow load and freeze-thaw.

Decks, porches, screened rooms and stone terraces that extend the season you can actually use them.

Careful work on antique and period homes — modern comfort without erasing what makes them worth keeping.
