Creating a custom home is a large undertaking and chances are you want to make the process as simple and enjoyable as possible. One great option that is becoming increasingly popular these days is to hire a design/build firm. Rather than scramble to employ the services of a top-notch architect and then hope that the general contractor you subsequently hire can implement their drawings and plans into the new home you imagine, within the budget you set out, a design/build firm integrates both services under one roof. By having the same people who design your new house be the ones who will be in the trenches building it, costs are often reduced and so is the overall project timeline.
If you decide to go the route of a design/build firm, sometimes referred to as master builders, we have you covered. We researched hundreds of options to come up with this list of the 10 best full-service design/build firms in California. These architecture and construction companies are generally concentrated in San Francisco, San Diego, and Los Angeles, but their services covered all of CA, from the sunny beaches of southern California to the hustle and bustle of the Bay Area, relaxing Wine Country, and beyond in northern California. Taken together, they are experts in contemporary architecture and classic, traditional building techniques. And included in the list are leaders in sustainable architecture and green building techniques. Many of these practices have worked with high profile clients, whether that is music moguls in LA and Beverly Hills or tech-leaders in Silicon Valley. So whatever type of new custom residential project you envision, the 10 CA design/build companies on this list can get the job done beautifully for you.
About our methodology: We considered hundreds of professionals while making this list of the 10 best design/build companies in California. In addition to professional associations, we heavily weighed recognition the firm has received in the form of awards and press, any prestigious clientele they have worked with, whether or not they collaborate with other top industry professionals, such as interior designers, and what areas they work in, the more exclusive and high-end neighborhoods having greater influence. We also took into account the value of the projects they undertake, years in the business, customer reviews for quality and service, and range of services offered. Finally, we considered geographic location in order to give you a good sampling of the best companies across the state.
