Architectural Design & Building

About Us

We’re an architecture firm north of Boston, dedicated to working closely with clients to help them realize their project goals, and we’ve done so for over seventeen years. We pride ourselves on our versatility, as we are capable of taking on a broad range of project types and locations, ranging from small home additions to large condominium developments and commercial projects.

Whether it’s designing functional, livable and beautiful spaces, navigating often complex municipal approval processes, designing for LEED certification, or coordinating with a multitude of engineers, consultants and contractors, our breadth of experience helps ensure a positive result for our clients.

The process of selecting an architect can sometimes be daunting, and we try to maintain a close working relationship with our clients to ensure that client input is understood, appreciated and above all, listened to. This is essential to making our projects successful for our clients, and why we love what we do.
