In-House Architect & Engineer
Architectural design and structural engineering under the same roof as construction — one team designs, permits, and builds.
Acre-plus hillside estates with demanding engineering — retaining structures, long driveways, and architect-driven custom construction.
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 Los Altos Hills and across Santa Clara 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.
Los Altos Hills keeps its rural character by rule: one-acre minimum lots, private lanes, the town pathway system, and properties that may run on septic rather than sewer. Projects here demand site-sensitive engineering and careful utility planning — exactly the ground-up estate work JMG self-performs with in-house crews.
