From First Sketch to Opening Day
A good commercial space does more than hold walls and doors—it has to fit the way your business works. At Integrity Development & Construction, we handle every part of the job under one roof. Our design‑build approach keeps things moving: fewer phone calls, fewer surprises, and one team that knows your project inside and out.
For over 30 years, we’ve been helping local businesses in the Pioneer Valley take old spaces and turn them into something that works—whether that’s a law office in Northampton, a nonprofit hub in Amherst, or a new retail fit‑out in Belchertown. We build with the schedule, the staff, and the day‑to‑day realities of your business in mind.
Local Expertise, Built for Business
We know Western Massachusetts buildings—the quirks, the permitting, and the timelines that make or break a commercial project. From three‑story mixed‑use buildings to small professional offices, our work is grounded in decades of local experience. That means when an unexpected code question comes up, we’ve probably seen it before and know how to keep things moving.
One Team, Start to Finish
Commercial projects can get complicated fast when architects, designers, and contractors are working in silos. With our design‑build process, we’re all one team. The person who helps sketch your first layout is in the same room as the team that orders materials and manages the carpenters on site.
That kind of collaboration matters—especially for small businesses and nonprofits where delays cost more than just time. We’ve opened law offices, financial suites, and community spaces on schedule because we keep communication tight and decisions clear.
Commercial Projects We Deliver
Our commercial portfolio covers a wide range of local projects:
- Law offices and professional suites
- Nonprofit and community organization spaces
- Veterinary clinics and small medical facilities
- Retail shops, cafés, and restaurant fit‑outs
- Mixed‑use and multi‑tenant buildings
We’ve worked in existing structures, new ground‑up builds, and even projects where the business needed to keep running while we built around them. Every space is designed to handle daily operations without wasted square footage or awkward layouts.
Why Businesses Choose Integrity
Our clients come back—or send their colleagues—because we keep the process grounded. We start by listening to what you actually need: the rooms, the functions, and the timeline. Then we walk you through budgets and permitting so there are no surprises along the way.
During construction, we stay on site and in touch. You’ll always know which stage your project is in, and we’ll flag decisions before they become last‑minute emergencies. Over three decades of building in the Pioneer Valley, that consistency has turned first‑time clients into long‑term partners.
Bringing Local Business Spaces to Life
Every commercial space in Western Massachusetts tells a story. We’ve taken empty storefronts and turned them into cafés that welcome a line out the door, and we’ve reworked old offices so staff can finally spread out and work comfortably.
Sometimes the work is subtle—like a fresh lobby and a better floor plan that makes a small professional suite feel twice the size. Other times, it’s transformative, such as converting a dated, multi‑room office into a light‑filled workspace for a growing nonprofit.
Our team respects what’s already there, whether it’s keeping original brick walls in an Easthampton storefront or saving beams in a century‑old Amherst building. We add what modern businesses need—better lighting, smarter layouts, and energy‑efficient touches—without losing the character that makes the space feel familiar.

We start with your goals, timeline, and how the space needs to function day to day.

We handle design, budgeting, and permitting up front to avoid surprises.
