At Brother & Brother Builders, we specialize in helping San Jose, CA homeowners add the square footage they have always wanted. Whether you're ready to build a new bedroom, a expanded living area, or a guest suite, room additions can make it happen.

What Room Additions Covers
Room additions cover a wide range of projects that span everything from constructing a new bathroom to major kitchen expansions. At their core, room additions mean physically extending your home's existing structure — either upward. This is different than remodeling, which reconfigures the existing walls.
These projects require a full range of trades that combines architectural planning, permit acquisition, foundation work, framing, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions involve multiple building disciplines, hiring a skilled construction team who can oversee every step is the key to a smooth project.
Room additions are a great fit for homeowners who need more room but prefer to stay in place. They're frequently selected for multigenerational households. Regardless of the scope, the work follows a structured set of stages that we have refined over many years.
