At Brother & Brother Builders, we are dedicated to helping San Jose, CA homeowners add the square footage they have always wanted. Whether you're dreaming of a new bedroom, a larger kitchen, or a sunroom, room additions can make it happen.
Home additions stand among the most valuable investments a homeowner can make.

What Home Addition Work Entails
Room additions cover a wide range of projects that span everything from adding a single bedroom to full second-story additions. At their foundation, room additions require adding to your home's current floor plan — either horizontally or vertically. This is distinct from remodeling, which works within the current square footage.
These builds require a coordinated effort that brings together architectural planning, city approvals, foundation work, framing, electrical, plumbing, insulation, drywall, and cosmetic detailing. Because room additions require so many interconnected trades, hiring a general contractor who can coordinate each phase is critical.
Room additions are a great fit for homeowners who want a dedicated space but want to keep their current property. They're also a popular choice for families welcoming new members. Regardless of the scope, the work follows a clear set of stages that our team have mastered through experience.
