About
Hi! I’m Michael, a California-licensed architect with over 15 years of experience in residential design. After years working in other states, I’m now based in Southern California, specializing in ADUs, custom homes, and renovations for single-family homes. Whether you’re converting a garage, planning a full remodel or a new home, I offer a comprehensive design service that guides you from concept through permitting — with a strong focus on clear communication and practical, buildable solutions. What sets us apart: • Customized design that balances function, aesthetics, and budget. • Accurate, permit-ready drawings(blueprints) and help navigating local approval processes. • We provide 3D renderings and virtual walkthroughs when needed — so you can clearly visualize your space before building. • My partner is a licensed structural engineer, and we work closely together to provide fully coordinated plans — no need to manage separate consultants. If you’re looking for thoughtful design, technical expertise, and a collaborative approach — we’d love to help bring your project to life.

Hired on Thumbtack

I can’t say enough good things about Space Plus Design, specifically about Michael Li, a licensed architect, on a project. I was looking to purchase a property in Tustin, and asked Michael to come along for his assessment on the listed property. He subsequently provided cost estimate for repairs needed or fixing defects, updating housing structure for higher ceiling and adding new ADU on the property. He also provided consultancy on what needed to be repaired and brought up the potential purchasing property to latest building codes for an older home built in the 1970’s. I appreciated his professionalism, attentive to details, and thorough in his responses to our requests. I definitely recommend Michael to anyone who needs architecture services or consultancy for home architecture assessment or home refurbishment.

Details: Design drawings • Project consultation • Construction documents (blueprints) • Complete remodel • Residential • 1,000 - 1,500 sq ft

Great experience working with Michael on our home remodel and garage-to-ADU conversion. They delivered great design service with attention to every detail. A solid choice for anyone starting a residential project.

They are a super nice and respond very quickly. We planed to demolish a kitchen wall but not sure if it’s load-bearing. They checked for me in the free consultation by getting into the attic. Nice people to work with. Very professional.
