When your household changes and your house no longer works for everyone, room additions offer a smart path to more space. At Brother & Brother Builders, we focus on helping San Jose, CA homeowners create the extra space they need. Whether you're ready to build a new bedroom, a functional office, or a guest suite, room additions are the answer.
Home additions are considered the most impactful investments a homeowner can make.

The result is a more comfortable home that fits the way you live for years to come.

What Room Additions Entails
Room additions encompass many different types of construction that include everything from constructing a new bathroom to large-scale family room builds. At their heart, room additions mean physically extending your home's current floor plan — either upward. This is different than remodeling, which reconfigures the existing walls.
These builds call for a full range of trades that involves architectural planning, permit acquisition, foundation work, rough construction, electrical, plumbing, insulation, wall systems, and cosmetic detailing. Because room additions involve multiple building disciplines, hiring a general contractor who can oversee every step is the key to a smooth project.
Room additions are a great fit for homeowners who have outgrown their current layout but aren't ready to move. They're frequently selected for homeowners planning to age in place. Regardless of the scope, the work follows a clear set of phases that our builders have executed on hundreds of projects.
