Adam Barnum, Owner

Barnum Building & Design remodels kitchens and bathrooms, builds room additions, renovates existing rooms, and provides other general contracting services for residential and commercial clients throughout San Francisco and the surrounding areas. As a full-service contractor, the company has the in-house capabilities to handle every step of its customers’ construction projects, from the design stage to the finishing touches.

Owner Adam Barnum credits much of Barnum Building & Design’s success to its comprehensive, detail-oriented approach to the remodeling process. “Having an eye for detail is important for narrowing in on the small aspects of a job, but it’s also  important for seeing the bigger picture,” he says. “We give equal attention to every phase of every project, and our clients really appreciate that.”

Barnum Building & Design also utilizes its C33 license to offer painting and interior decorating services, which eliminates the need for clients to hire more than one company to handle extensive remodeling and renovation jobs. “I actually started as a painting contractor in Martha’s Vineyard, so I bring a lot of experience to the design aspects of our clients’ projects,” says Mr. Barnum. “From conception to completion, we can do it all.”

Company Philosophy

“We love interacting with our clients and utilizing our expertise to make their remodeling dreams come true. By getting  to know them and listening closely to their ideas, we’re able to deliver exactly what they want—and sometimes even more.”
