In-House Architect & Engineerserving all of California.

Architectural design and structural engineering under the same roof as construction — one team designs, permits, and builds.

Most projects stall in the handoff between designer, engineer, and builder. JMG eliminates it: architectural design, structural calculations, Title 24 energy compliance, and permit-ready construction drawings are produced in-house and coordinated directly with the crews who will build them.

From custom estate architecture in Atherton to engineered tenant improvements for national retail brands, every design decision is made with real construction knowledge — so what gets drawn is exactly what gets built, on budget and on schedule, under California Contractor's License #1007864.

Architect & Engineering — frequently asked questions

Not with JMG. Design, structural engineering, and permitting happen in-house — one contract and one accountable team from first sketch to final inspection, which removes the most common source of delays and change orders.
