In-House Architect & Engineer
Architectural design and structural engineering under the same roof as construction — one team designs, permits, and builds.
High-income residential remodeling minutes from Sand Hill Road — venture-capital discretion with builder-grade accountability.
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.
In Menlo Park and across San Mateo County, JMG delivers architect & engineering under California Contractor's License #1007864 — permitted, inspected, and personally overseen by owner Jerry Guinn. 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.
Menlo Park runs from Allied Arts and Sharon Heights estates to Belle Haven infill — with flood-zone considerations near the Bay and a building department that expects complete submittals. We deliver estate remodels, retail work along Santa Cruz Avenue and El Camino Real, and ADUs engineered to the city's standards.

Architect & Engineering in Menlo Park — FAQ
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.
