“We absolutely loved working with Tim to design our dream home! From the moment me met with Tim, he knew exactly what we wanted and brought our vision to life. There were many aspects of our home we didn’t even know we wanted. Working with Tim was so easy and made the stressful process of designing a home seamless. Definitely recommend working with Tim if you’re looking for a fantastic architect!”

“I've worked closely with Bret Walters at John Lum Architecture for the past 2+ years on what was effectively a new construction house in San Francisco, and while I'm thrilled for the client to have moved into his gorgeous new home, and couldn't be more proud of the finished product and the collaboration between me (I was the interior designer on the project) and Bret + the JLA team, I'm also honestly SO sad that I don't get to work with Bret all the time anymore. I have to admit that I was a big fan of John Lum Architecture for years before I had the opportunity to work with them; and the creative, clever, practical, and human-first design thinking they brought to every aspect of the project that I was involved in, was top-notch. They also are innovative not only in the design process but in the construction management aspects: for example, they introduced the entire project team (owner's rep, interior designer, contractor, client) to the software PlanGrid to keep track of drawings, construction issues, etc. in the cloud. To me this shows they're always exploring new technologies and ways to make their work more efficient, collaborative, and cutting-edge. And I can't say enough great things about Bret: he's extremely professional, a wealth of knowledge, a great listener / communicator, responsive, hard-working, and fun to collaborate with. He is also level-headed so that when something goes wrong in construction (which something always does), his approach is to stay focused on how to resolve and fix the issue. This project was NOT without its share of drama and sometimes-difficult personalities, and I was often impressed with Bret's ability to navigate those situations. I'd love to be able to work with Bret and the JLA team again on a future client's home. And unrelated to anything practical, John's pint-sized pitbull April is often at the office and she is my favorite office dog ever!”
