Why one team matters
Separating architects and structural engineers causes finger-pointing, revision delays, and wasted fees.
No gaps between the architect and the engineer
Design intent and structural framing align from day one. Structural beams are coordinated directly with ceiling heights, window openings, and plumbing paths.
One point of contact from design to permit
You never have to coordinate emails between separate firms. Rafael Macedo and our team manage architectural layouts, civil siting, and structural stamps seamlessly.
We answer the building department's comments with you
If the municipal building inspector or plan examiner asks for structural clarifications or revisions, our engineers address comments directly until the permit is issued.
How it works
Three straightforward steps from your initial request to permit-ready drawings.
1. Tell us about your project in the form (2 minutes)
Share your property location in MA, project scope (ADU, addition, or specific structural stamp), and your contact info.
2. We review it and send you a clear estimate
Our team evaluates your scope and responds with an exact scope of architectural drawings, structural calculations, and timeline.
3. We design, stamp and support you through the permit
We produce fully stamped permit drawings, coordinate with your builder, and respond directly to building department plan reviews.
