HOW WE WORK
Our Architectural Design Process for California Projects
Consultation (Free Consultation)
We discuss your vision, budget, and requirements to establish a clear project roadmap.
Design & Drafting
Our team creates detailed architectural design plans and 3D visualizations for your approval.
Permit Processing
We handle all city submissions and corrections to ensure your project is fully compliant.
Final Approval
You receive your approved plans, ready for construction to begin with total confidence.
The Turnkey Advantage
The Best Choice for Custom Architectural Space Design in California
Most projects stall in the handoff between designer and contractor, and you end up in the middle. We keep design, drafting and permits under one roof, so one person is accountable from start to finish.
Permit Approval Guarantee
We’ve sat across the table from California plan checkers for 10+ years. We know exactly what each city flags, so your plans pass inspection without the usual back-and-forth.
Customized Design Solutions
No cookie-cutter templates. Every architectural design is built around your lot, your lifestyle, and what you’re trying to get out of the investment.
End-to-End Management
One team manages your project from the first sketch to the final permit stamp. You’re not stuck translating between a designer, a drafter, and a permit runner.
Heritage, Leadership & Local Presence
Our Design Studio in California
Founded in 2014, Jean-Prescott Studio is an independent California design studio built on precise drafting and long-term clients.
