A Complete Guide to Design Build for Custom Home Projects

Design build addresses that challenge by uniting the whole build under one team.
At Brother & Brother Builders, we have been providing design build solutions across San Jose, CA with deep expertise.

What Is a Design Build Contract?
Design build is a home building method where a sole entity handles both the architectural design and the physical construction of your home. In contrast to the traditional separated model, design build means you have a single team responsible for everything, from lot assessment and floor plan creation through framing and final details.
Mechanically, the design build process works by combining the design and construction phases so they overlap and inform each other rather than handing off separately. A Brother & Brother Builders design build team typically includes licensed architects, project planners, and trade partners who collaborate constantly. This results in the fact that if a design detail is outside budget, it gets revised early rather than showing up as an expensive surprise.
The design build framework is especially well-suited for custom new home construction because every decision — from room orientation to exterior finishes — is assessed through both a creative eye and a construction feasibility lens at once. The payoff is a home that matches the original concept and is built efficiently.
