Design & build contractors
One team from first sketch to final build
A lot of contractors can build. A lot of designers can draw. Finding one firm that does both — and does both well — is rarer than it should be. At Bay State Design & Construction, design and construction have always lived under the same roof. That's not a selling point. It's just how we work.

Our Approach
We’re the best of both words: design and build
Most homeowners don't realize how much gets lost in the handoff between a design firm and a contractor. The plans come back over budget. The contractor interprets something differently than the designer intended. The timeline slips because no one owns the whole process. We built BSDC around a simple idea — that design and construction should never be separated. We take your initial idea, develop it into a full set of drawings, model it in 3D so you can see exactly what you're getting, handle engineering and plot plans, pull every permit, and build it ourselves. From the first conversation to the final walkthrough, you're working with one team.
Sometimes a project grows beyond a single remodel or addition into something more — a self-contained living space, an ADU, or a full property build-out. If that's where yours is headed, our FlexUnit™ service might be the smarter path.
WHY DESIGN & BUILD
Why does the design and build model matter?
- One team owns the project from concept to completion — no finger pointing between firms
- Your budget is set at the design stage, not after the plans are already drawn
- Design decisions get made by people who understand how to build them
- Permits, engineering, and construction documents are handled in-house
- Your timeline is controlled by one firm, not dependent on another firm's schedule
- What you approve in the design phase is what gets built — no surprises

Great guys and easy to work with! I couldn't be happier with my beautiful new kitchen!
The best! Gave a super reasonable estimate and walked me through all the steps and timeline , finally have my (dream) kitchen.
I highly recommend Bay State Design & Construction to anyone looking for reliable, skilled, and professional construction services.
These guys are amazing! Helped me build a two story addition with a master suite and I couldn't be more thrilled with the product.
The guys from Bay State design were prompt well priced and kept my project moving without missing a step. Great work guys!
I hired these guys to build an attached garage at my house. Throughout the entire process they went above and beyond all expectations and their pricing was super fair.
This team is very professional, communicative and great to work with. Gio provided comprehensive building plans for me within a short timeframe, as promised.

Why homeowners choose BSDC
One point of contact, start to finish
No chasing down architects, contractors, or permit offices. You have one team and one person to call, from first sketch to final walkthrough.
We design around your budget
Many firms design the dream, then hand you a bill that doesn't match it. We start with your number and build the plan around it — no sticker shock.
Your vision survives the build
A lot gets lost when the design firm hands off to the contractor. We can draw the plans and build to them. AKA: what you approved is what gets built.
Your timeline is ours to protect
When design and construction live under one roof, no one else's schedule can slow yours down. We control the process so you're not waiting on a separate third party to move forward.
Frequently Asked Questions
Design & build FAQs
A design and build contractor handles both sides of a project — the design and the construction — under one roof. That means one contract, one point of contact, and one team responsible for the outcome from start to finish.
When you hire separately, you're the one managing the relationship between two firms. If something gets lost in translation between the design and the build, that's your problem to sort out. With a design and build firm, that's our problem — and our job to prevent it from happening in the first place.
We start with your idea and your budget. From there we develop drawings, produce 3D renderings so you can visualize the space before anything gets built, handle any engineering requirements, and prepare full permit documentation. You sign off before a single nail goes in.
Yes. Permit documents, engineering, and plot plans are all handled in-house. We know what each municipality requires and manage the process so you don't have to.
It depends on the plans. We're happy to review what you have and tell you honestly whether we can build from them or whether they need to be redeveloped. Either way, we make sure the construction documents are right before we break ground.
Kitchen and bathroom remodels, home additions, floor plan reconfigurations, basements, ADUs, and larger custom builds. If it involves design and construction in Central or Greater Massachusetts, we're worth a call.
Every project comes with a 1-year workmanship warranty. If something isn't right with our work, we come back and make it right.
