Additions & Extensions

Expanding your home is about more than adding square footage—it’s about making space for the life you’re living now. Whether it’s a new bedroom, larger kitchen, or a true primary suite, we design additions that feel seamless, intentional, and built to belong.

From the first idea to the final coat of paint, we create additions that feel like they’ve always been part of your home. Because this isn’t just extra space—it’s where new routines, memories, and moments begin.

Vision Planning

We start by listening—how your family lives, what’s missing, and what you want more of. Then we work together to create a plan that fits your space, timeline, and budget.

Architectural Drawings & Engineering

Once the vision is in place, we bring in trusted architects and engineers to develop plans that are functional, buildable, and fully tailored to your home.

Permits, Surveys & Zoning Approvals

We handle the logistics—from zoning and variance checks to permit filing—so you don’t have to navigate town regulations on your own.

Primary Suites & Bedroom Additions

Need a true retreat or extra sleeping space? We build primary suites, kids’ rooms, and guest bedrooms that feel private, peaceful, and perfectly integrated.

Kitchen Expansions & Open Concept Living

Whether it’s knocking down a wall or building out into the yard, we create open, airy spaces made for cooking, gathering, and everyday connection.

Bathrooms, Laundry Rooms & Mudrooms

Functional upgrades can make a world of difference. We add storage-smart mudrooms, family bathrooms, and laundry spaces that simplify daily routines.

Seamless Exterior & Structural Integration

We match your addition to the existing structure—visually and structurally—so it looks and feels like it was always meant to be there.

Final Walkthrough & Move-In

We walk you through every detail, from flooring and paint to fixtures and trim, making sure the new space is not just beautiful—but ready to use and enjoy from day one.

“We knew we needed more space, but we didn’t want to leave the home and neighborhood we love. New Hampton Construction helped us expand both up and out, adding a beautiful master suite and a home office that finally gives us room to breathe. The new layout feels effortless—like it was always meant to be this way.”
