At Brother & Brother Builders, we are dedicated to helping San Jose, CA homeowners create the extra space they deserve. Whether you're ready to build a new bedroom, a expanded living area, or a sunroom, room additions turn that vision into reality.

What Home Addition Work Entails
Room additions are a broad category that include everything from constructing a new bathroom to major kitchen expansions. At their heart, room additions require adding to your home's existing structure — either horizontally or vertically. This is not the same as remodeling, which works within the current square footage.
These undertakings demand a collaborative approach that brings together architectural planning, city approvals, foundation work, framing, electrical, plumbing, insulation, wall systems, and flooring and trim. Because room additions touch so many systems, choosing a experienced builder who can manage all of it is critical.
Room additions are a great fit for homeowners who want a dedicated space but prefer to stay in place. They're also a popular choice for homeowners planning to age in place. Whether it's a small bump-out or a full-scale addition, the process follows a structured set of steps that we have refined over many years.
