At Brother & Brother Builders, we are dedicated to helping San Jose, CA homeowners create the extra space they need. Whether you're dreaming of a new bedroom, a expanded living area, or a sunroom, room additions are the answer.

What Home Addition Work Covers
Room additions are a broad category that involve everything from constructing a new bathroom to full second-story additions. At their core, room additions require adding to your home's current floor plan — either upward. This is distinct from remodeling, which stays inside the original layout.
These builds require a collaborative approach that involves architectural planning, city approvals, foundation work, rough construction, electrical, plumbing, insulation, interior finishing, and final finishes. Because room additions involve multiple building disciplines, choosing 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 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 structured set of steps that our builders have refined over many years.

A interior update stays inside the existing footprint without increasing total size. Room additions generally involve more complex construction than a standard remodel.
