At Brother & Brother Builders, we focus on helping San Jose, CA homeowners create the extra space they have always wanted. Whether you're dreaming of a new bedroom, a expanded living area, or a guest suite, room additions turn that vision into reality.
Home additions stand among the most impactful investments a homeowner can make.

The end product is a better-functioning home that serves your household check here for decades ahead.
San Jose is home to a wide range of property types, from mid-century ranchers. Our team understands how to match new construction to enhance the original style of your home. Room additions executed well should look like they were always there.
What Room Additions Covers
Room additions are a broad category that span everything from constructing a new bathroom to major kitchen expansions. At their core, room additions involve expanding your home's current floor plan — either horizontally or vertically. This is different than remodeling, which reconfigures the current square footage.
These builds require a collaborative approach that combines architectural planning, building permits, foundation work, framing, electrical, plumbing, insulation, interior finishing, and cosmetic detailing. Because room additions touch so many systems, working with a general contractor who can manage all of it is critical.
Room additions are ideal for homeowners who need more room but want to keep their current property. They're also a popular choice for multigenerational households. No matter the size, the approach follows a clear set of steps that our builders have mastered through experience.

Common Questions About Room Additions
Homeowners considering room additions often have the same important concerns. Here are honest answers to the most common ones:
How much do room additions typically cost in San Jose?Room addition investment levels in San Jose range considerably based on square footage and materials. A basic square addition might start around $150,000–$200,000, while complex custom expansions can reach well into the six-figure range. During your consultation, we give you a clear breakdown specific to what you're planning.
What's the typical timeline for room additions?The average home addition project spans four to ten months from permit approval to final inspection. Multi-room or second-story additions may take longer. The permit process can take up a large chunk of that total schedule.
Are permits required for home additions?Always — any room addition that adds square footage requires permits from the city in San Jose. Skipping permits create serious problems at resale. Our team takes care of this entirely so nothing falls through the cracks.
What's the difference between a room addition and a home remodel?A room addition adds to your home's total square footage by extending the structure outside the existing floor plan. A renovation works within what's already there without adding new area. Room additions generally involve larger in scope construction than finish upgrades.
Will a room addition match the rest of my house?Blending new construction with the original structure is one of our core goals on every room addition build. Our crew sources exterior materials, rooflines, siding, and trim to align with your home's existing style. The finished product is an addition that feels intentional rather than tacked on as an afterthought.
