At Brother & Brother Builders, we specialize in helping San Jose, CA homeowners add the square footage they have always wanted. Whether you're dreaming of a new bedroom, a functional office, or a sunroom, room additions are the answer.

What This Type of Project Entails
Room additions are a broad category that include everything from constructing a new bathroom to large-scale family room builds. At their foundation, room additions involve expanding your home's footprint — either upward. This is different than remodeling, which stays inside the existing walls.
These builds require a collaborative approach that involves architectural planning, building permits, foundation work, structural carpentry, electrical, plumbing, insulation, wall systems, and flooring and trim. Because room additions require so many interconnected trades, hiring a experienced builder who can coordinate each phase is the key to a smooth project.
Room additions are a great fit for homeowners who need more room but aren't ready to move. They're often the right move for families welcoming new members. Whether it's a small bump-out or a full-scale addition, the work follows a structured set of stages that we have refined over many years.
