At Brother & Brother Builders, we specialize in helping San Jose, CA homeowners add the square footage they deserve. Whether you're dreaming of a new bedroom, a functional office, or a sunroom, room additions are the answer.
Home additions are considered the most meaningful investments a homeowner can make.

The end product is a more comfortable home that fits the way you live for the long haul.
San Jose features a broad variety of architectural styles, from modern two-story builds. Our builders understands how to blend additions seamlessly to complement the current structure of your home. Room additions done right should blend naturally into the existing footprint.
What Room Additions Covers
Room additions are a broad category that span everything from constructing a new bathroom to major kitchen expansions. At their foundation, room additions require adding to your home's existing structure — either upward. This is distinct from remodeling, which works within the original layout.
These projects demand a collaborative approach that brings together architectural planning, city approvals, foundation work, rough construction, 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 commonly chosen by homeowners who have outgrown their current layout but aren't ready to move. They're often the right move for homeowners planning to age in place. Regardless of the scope, the work follows a well-defined set of steps that our team have refined over many years.
