At Brother & Brother Builders, we are dedicated to helping San Jose, CA homeowners add the square footage they have always wanted.

What Home Addition Work Entails
Room additions are a broad category that involve everything from constructing a new bathroom to large-scale family room builds. At their core, room additions involve expanding your home's footprint — either horizontally or vertically. This is distinct from remodeling, which stays inside the original layout.
These projects call for a collaborative approach that combines architectural planning, permit acquisition, foundation work, rough construction, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions require so many interconnected trades, hiring a skilled construction team who can oversee every step is the key to a smooth project.
Room additions are ideal for homeowners who have outgrown their current layout but aren't ready to move. They're often the right move for families welcoming new members. Regardless of the scope, the work follows a clear set of phases that our team have mastered through experience.
