At Brother & Brother Builders, we specialize in helping San Jose, CA homeowners build the additional rooms 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.

San Jose is home to a broad variety of architectural styles, from mid-century ranchers. Our crew understands how to blend additions seamlessly to complement the original style of your home. Room additions executed well should look like they were always there.
What Room Additions Entails
Room additions are a broad category that include everything from adding a single bedroom to major kitchen expansions. At their heart, room additions mean physically extending your home's current floor plan — either upward. This is not the same as remodeling, which stays inside the original layout.
These projects call for a collaborative approach that involves architectural planning, building permits, foundation work, rough construction, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions touch so many systems, working with a experienced builder who can manage all of it is the key to a smooth project.
Room additions are commonly chosen by homeowners who need more room but want to keep their current property. They're often the right move for homeowners planning to age in place. No matter the size, the process follows a structured set of stages that our team have executed on hundreds of projects.
