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

San Jose has a broad variety of architectural styles, from classic craftsman bungalows. Our crew understands how to design expansions to work with the original style of your home. Room additions done right should blend naturally into the existing footprint.
What Home Addition Work Entails
Room additions encompass many different types of construction that include everything from building an attached garage to full second-story additions. At their foundation, room additions involve expanding your home's existing structure — either upward. This is distinct from remodeling, which reconfigures the existing walls.
These builds require a coordinated effort that involves architectural planning, permit acquisition, foundation work, framing, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions require so many interconnected trades, working with a general contractor who can coordinate each phase is essential.
Room additions are a great fit for homeowners who have outgrown their current layout but want to keep their current property. They're frequently selected for families welcoming new members. Regardless of the scope, the approach follows a well-defined set of stages that our team have executed on hundreds of projects.

Common Questions About Room Additions
People planning room additions usually bring up the same core questions. These are direct answers to the most common ones:
How much do room additions typically cost in San Jose?Room addition costs in San Jose vary widely based on square footage and materials. A basic square addition might start around $150,000–$200,000, while second-story builds can reach well into the six-figure range. During your consultation, we give you a clear breakdown specific to your goals.
What's the typical timeline for room additions?The average home addition project runs approximately four to eight months from breaking ground to move-in. Multi-room or second-story additions may take longer. Getting permits through can take up a noticeable share of that overall timeline.
Do room additions require permits in San Jose?Without exception — any room addition that expands your home's footprint requires proper city approval in San Jose. Building without approval can result in fines and forced demolition. We takes care of this entirely so you're covered from a compliance standpoint.
What's the difference between a room addition and a home remodel?A room addition adds to your home's overall footprint by building new rooms beyond the current walls. A remodel stays inside what's already there without increasing total size. Room additions are typically more extensive construction than a standard remodel.
Will a room addition match the rest of my house?Blending new construction with the original structure is a central focus on every room addition build. Our team sources structural elements and surface materials to complement your current exterior. The result is an addition that appears original rather than bolted on.
