Residential Design-Build in the Pioneer Valley

Custom homes, additions, and living spaces designed for the way you live.

When you build a home—or change the one you already love—you want more than square footage. That’s what we do at Integrity Development & Construction. We handle the design and the construction as one team, so the process is smoother and decisions get made without the back‑and‑forth that slows projects down.

We’ve been building in Western Massachusetts for over 30 years. As a woman‑owned, local firm, we’ve helped families create custom homes, ADUs, and major additions all over the Pioneer Valley. Whether it’s a new build or a transformation of a space you’ve outgrown, our goal is simple: a home that feels right and lasts for decades.

Woman-Owned & Local Since the 1990s

For more than 30 years, we’ve been designing and building homes that fit the Pioneer Valley. From kitchens and additions to full custom homes, our work is rooted in careful craftsmanship and a deep knowledge of Western Massachusetts homes. Being a local, woman‑owned firm simply means the people and places here matter to us—and it shows in every project we take on.

One Team, Start to Finish

A design‑build project means you’re working with one team the whole way through. We sketch, plan, coordinate, and build—all under the same roof. That means fewer delays, clear communication, and a home that reflects your life instead of a set of disconnected plans.

Many of our residential projects start with a renovation or a major addition ([Renovations & Remodels]). Planning for the future can look like adding a first‑floor bedroom or a no‑threshold shower ([Aging-in-Place & Universal Design]).

Some projects lean the other way—energy‑conscious improvements ([Energy-Efficient & Sustainable Projects]) that make the house cozier in winter and easier on the heating bill.

Custom Homes & Large Additions

From ground‑up custom homes to expansive additions and ADUs, our team creates spaces that feel personal and last for decades.

  • Custom homes tailored to how you actually live
  • Multi-room or second‑story additions to expand living space
  • ADUs for extended family or private guest space

We combine design expertise with practical construction experience, so your new space looks great and works for the long run.

Renovations & Transformations

Some of our favorite projects start with houses that people still love—but something about them just doesn’t work. Maybe the kitchen stays dark no matter how many lamps you add. Or there’s an old barn out back that’s never been more than storage. Turning spaces like that into places you actually use can make the whole home feel new again.

Full‑home remodels usually become a mix of keeping what matters and rethinking the parts that don’t. That might mean saving the original wood floors, or opening up walls so rooms finally flow together.

Why Clients Choose Integrity

Our clients often tell us the same thing: “You listened and made the process easy.”

  • We take time up front to understand how you want to live.
  • We stay in touch throughout the project so nothing feels like a surprise.
  • And we build carefully, creating spaces that last.

Most of our work comes from referrals or repeat clients, which is the best sign we’re doing it right.

Historic Homes & Barn Conversions

Western Massachusetts homes have stories—and sometimes, quirks. We’ve turned barns into bright living spaces and opened up farmhouses that hadn’t seen sunlight in decades.

Every project starts with respect for what’s there. Maybe that’s keeping exposed beams, or reusing old flooring where it makes sense. Then we blend in modern function and energy-smart choices so the space works for life today without losing its history.

Your Home, Designed to Fit Your Life

When we get involved early, the project runs smoother. You get a design that fits your lifestyle and a team that carries it through to the final walkthrough.

Our Residential Process

Every project follows a simple flow:


Listen First

We start with your goals and how you want the home to feel.

Design & plan

We create a plan with realistic timelines and cost estimates.

Build with care

Our team handles each step and keeps you in the loop the entire way.

Energy-Conscious by Nature

Even if the project starts with style or space in mind, we often recommend small upgrades—better insulation, smart window placement, and durable materials that stand up to New England seasons. Those choices add comfort, cut long‑term costs, and help your home run efficiently.

Living Through a Remodel

If your project isn’t a new build, we plan carefully to minimize disruption. We section off work areas, keep things tidy, and communicate so you can keep living your life while your home changes around you.
