Expanding Your Living Space with Professional Room Additions
When your household changes and your current home no longer fits your needs, room additions provide a practical path forward. At Brother & Brother Builders, we are dedicated to helping San Jose, CA homeowners build the additional rooms they need. Whether you're ready to build a new bedroom, a expanded living area, or a sunroom, room additions turn that vision into reality.
Home additions are considered the most valuable investments a homeowner can make.

The outcome is a well-designed home that fits the way you live for decades ahead.

What Room Additions Entails
Room additions cover a wide range of projects that involve everything from building an attached garage to major kitchen expansions. At their foundation, room additions require adding to your home's footprint — either upward. This is different than remodeling, which works within the current square footage.
These undertakings demand a collaborative approach that involves architectural planning, building permits, foundation work, rough construction, electrical, plumbing, insulation, wall systems, and flooring and trim. Because room additions require so many interconnected trades, working with a skilled construction team 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 frequently selected for multigenerational households. Whether it's a small bump-out or a full-scale addition, the approach follows a well-defined set of stages that our team have executed on hundreds of projects.
