Architecture & Engineering Services in Greater Boston & New England
Terrapin Construction Group delivers architecture, structural engineering, and MEP engineering in-house for Greater Boston commercial projects from 50 Milk St, 16th Floor, Boston, MA 02109. Because design and construction sit under one roof, the drawings are built to be built, not handed across a gap to a contractor who reprices them.
Integrated design-build is the difference. TCG's architects and engineers work directly with the construction team from concept, which means constructability, cost, and schedule are designed in from day one. In a high-cost union market with historic preservation constraints and tight permitting, that integration compresses schedule 15-30% and cuts change orders. Read what a design-build contractor does.
From feasibility and programming through permitting and construction documents, TCG carries the whole design through a single design-build contract. Learn more about commercial architectural services, costs, and value.
Why TCG for Design-Build in Boston
Drawings built to be built. In-house architecture and engineering means constructability and cost are designed in, not discovered in bidding.
One contract, one accountability. Design-build removes the owner from the middle of design-versus-construction disputes and compresses schedule 15-30%.
Boston fluency. Historic preservation, ISD permitting, and union-market realities shape the design from the start.
All disciplines in-house. Architecture, structural, and MEP under one roof, proven on Massachusetts design-build work including cannabis facilities in Worcester, Dracut, and Abington.
Massachusetts Design-Build & GC Projects
Massachusetts facilities TCG delivered through design-build and full general contracting, with in-house architecture and engineering. Each links to our full project portfolio.
The High End
Full general contractor with self-performed IMP installation. Four-story redbrick adaptive-reuse conversion into a vertically integrated cannabis cultivation, processing, and retail facility.
Lazy River
Design-build cultivation and dispensary facility north of Lowell in the Merrimack Valley.
What Do Architecture & Engineering Cost in Boston?
Architecture and engineering fees typically run as a percentage of construction cost, varying by building type and complexity, with soft costs (permitting, surveys, geotech, commissioning) on top. Design-build folds these into one number and reduces the change orders that inflate design-bid-build.
| Scope | Boston Range |
|---|---|
| Simple shell / warehouse A&E | 6-9% of construction |
| Standard commercial A&E | 8-12% of construction |
| Complex clinical / lab / cannabis A&E | 10-15% of construction |
| Soft costs (permits, surveys, geotech) | 5-12% of construction |
Design-build typically lowers total delivered cost versus design-bid-build by compressing schedule and reducing change orders. Use the estimator above for a construction-cost range, or read our A&E fees and soft costs guide.

Yes. TCG provides in-house architecture, structural engineering, and MEP engineering, integrated directly with the construction team under one design-build contract.
Design-build puts design and construction under one contract, so constructability and cost are designed in from the start. It typically compresses schedule 15-30% and reduces change orders and design-versus-construction disputes.
Yes. Historic preservation constraints, City of Boston ISD permitting, and union-market realities are built into TCG's design from concept, which avoids costly rework later.
Yes. TCG has delivered design-build cannabis projects in the Commonwealth, including Lazy River in Dracut (30,000 SF cultivation and dispensary), Elevated Roots in Abington (3,800 SF dispensary), and The High End in Worcester (25,000 SF vertically integrated).
No. TCG can start from a concept and provide architecture, structural, and MEP through construction. TCG can also bid and build from owner-provided plans.
By compressing schedule and reducing change orders, design-build typically lowers total delivered cost versus design-bid-build, even though design and construction are bundled into one contract.
All of Greater Boston and Massachusetts, including Worcester, Cambridge, and the suburban corridors, plus throughout New England.
