At Brother & Brother Builders, we specialize in helping San Jose, CA homeowners create the extra space they have always wanted. Whether you're dreaming of a new bedroom, a functional office, or a dedicated workspace, room additions are the answer.
Home additions are considered the most meaningful investments a homeowner can make.

What Home Addition Work Entails
Room additions encompass many different types of construction that include everything from constructing a new bathroom to major kitchen expansions. At their foundation, room additions involve expanding your home's current floor plan — either upward. This is not the same as remodeling, which stays inside the existing walls.
These undertakings call for a collaborative approach that combines architectural planning, city approvals, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and cosmetic detailing. Because room additions require so many interconnected trades, hiring a general contractor who can coordinate each phase is the key to a smooth project.
Room additions are commonly chosen by homeowners who want a dedicated space but prefer to stay in place. They're also a popular choice for families welcoming new members. Whether it's a small bump-out or a full-scale addition, the approach follows a structured set of phases that our builders have executed on hundreds of projects.

How many months does a room addition project take?A typical room addition build spans four to eight months from breaking ground to move-in. Multi-room or second-story additions sometimes push past a year. The permit process often accounts for a significant portion of that overall timeline.

Unpermitted additions create costly legal and financial consequences. Our builders takes care of this entirely so you're covered from a compliance standpoint.
