One of the advantages of working with a design-build firm is that homeowners can work with a designer and contractor from a single firm. Working with just one contact usually promotes a unified and collaborative method from the conceptualization stage through the construction of the project. Problem-solving and innovation are easier to achieve when working with a team of professionals from the same firm since they share the same goals and principles. 

For homeowners in Santa Monica, California looking for that convenience, this list includes some of the best design-build firms working in the area. These trusted firms have years of industry experience, awards, publication features, and impressive projects.
