At Brother & Brother Builders, we focus on helping San Jose, CA homeowners build the additional rooms they need. Whether you're dreaming of a new bedroom, a expanded living area, or a guest suite, room additions can make it happen.
Home additions are considered the most meaningful investments a homeowner can make.

The outcome is a more comfortable home that serves your household for the long haul.
San Jose is home to a diverse mix of architectural styles, from modern two-story builds. Our crew understands how to blend additions seamlessly to complement the existing character of your home. Room additions completed properly should blend naturally into the existing footprint.
What This Type of Project Involves
Room additions cover a wide range of projects that involve everything from building an attached garage to full second-story additions. At their heart, room additions mean physically extending your home's existing structure — either outward. This is distinct from remodeling, which stays inside the existing walls.
These projects demand a collaborative approach that combines architectural planning, permit acquisition, foundation work, structural carpentry, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions touch so many systems, working with a general contractor who can coordinate each phase is the key to a smooth project.
Room additions are a great fit for homeowners who need more room more info but aren't ready to move. They're also a popular choice for homeowners planning to age in place. No matter the size, the process follows a well-defined set of steps that our team have refined over many years.
