At Brother & Brother Builders, we specialize in helping San Jose, CA homeowners add the square footage they deserve. Whether you're planning for a new bedroom, a expanded living area, or a sunroom, room additions can make it happen.

What This Type of Project Entails

Room additions are a broad category that include everything from building an attached garage to full second-story additions. At their core, room additions require adding to your home's footprint — either upward. This is not the same as remodeling, which works within the current square footage.

These projects call for a collaborative approach that involves architectural planning, building permits, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and cosmetic detailing. Because room additions touch so many systems, hiring a general contractor who can coordinate each phase is essential.

Room additions are ideal for homeowners who need more room but prefer to stay in place. They're also a popular choice for families welcoming new members. Regardless of the scope, the approach follows a clear set of stages that our team have executed on hundreds of projects.
