Structural engineering, New England

JGray Engineering pairs structural expertise with real building experience.

For the architects and builders behind New England's finest custom homes, we design as if we were building it ourselves, because we have.

For architects, that means a true collaborator who protects the design intent and finds the structural path to make ambitious ideas stand. For builders, it means plans that are genuinely easy to build from, with trade sequencing in mind and conflicts resolved on paper instead of discovered on site.

How we work

Involved from the first line. Making your work easier.

01
Understand & anticipate
It starts with understanding what the project actually needs, working alongside the architect from the first sketch and the builder from preconstruction. Every potential problem gets mapped and the fix engineered in design: resolved on paper, not on site.
02
Design & draft
Easy-to-read, color 2D plans delivered with a 3D structural model, coordinated with the architectural set. Field-ready documents engineered to make the build faster and easier: drawings that work as well on site as they do on paper.
03
On site with you
Direct access to Jeff through construction. RFIs answered fast, site visits when the project needs them, and questions resolved in real time to keep the job on schedule.
The difference

He built the houses before he engineered them.

Founder Jeff Gray II grew up in the construction industry, in his family's structural design and specialty lumber business. Cutting I-joists and beams, walking jobsites, studying framing plans, and framing houses himself: he learned firsthand how his designs actually go together.

That foundation, paired with his civil engineering degree and over six years practicing at residential structural firms across New England, led him to found JGray Engineering, combining real construction experience with structural expertise. A structural design isn't finished when it's code-compliant. It's finished when it honors the architecture and makes the build easier in the field.
