At Brother & Brother Builders, we specialize in helping San Jose, CA homeowners create the extra space they need.

What Home Addition Work Entails
Room additions encompass many different types of construction that span everything from building an attached garage to major kitchen expansions. At their core, room additions involve expanding your home's footprint — either horizontally or vertically. This is different than remodeling, which stays inside the existing walls.
These projects call for a coordinated effort that combines architectural planning, building permits, foundation work, rough construction, electrical, plumbing, insulation, interior finishing, and cosmetic detailing. Because room additions involve multiple building disciplines, working with a experienced builder who can oversee every step is critical.
Room additions are ideal for homeowners who need more room but want to keep their current property. They're often the right move for homeowners planning to age in place. No matter the size, the process follows a structured set of stages that our team have refined over many years.
