At Brother & Brother Builders, we are dedicated to helping San Jose, CA homeowners add the square footage they have always wanted. Whether you're dreaming of a new bedroom, a expanded living area, or a sunroom, room additions are the answer.

The end product is a well-designed home that fits the way you live for decades ahead.
San Jose has a diverse mix of home designs, from mid-century ranchers. Our team understands how to blend additions seamlessly to enhance the existing character 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 involve everything from constructing a new bathroom to major kitchen expansions. At their core, room additions require adding to your home's existing structure — either outward. This is different than remodeling, which works within the original layout.
These projects demand a coordinated effort that involves architectural planning, permit acquisition, foundation work, rough construction, electrical, plumbing, insulation, interior finishing, and final finishes. Because room additions require so many interconnected trades, working with a general contractor who can manage all of it is essential.
Room additions are ideal for homeowners who need more room but aren't ready to move. They're often the right move for multigenerational households. Whether it's a small bump-out or a full-scale addition, the approach follows a structured set of steps that our team have refined over many years.

What Homeowners Ask About Room Additions
People planning room additions typically come to us with the same recurring topics. Below are straightforward responses to the questions we hear most:
What should I budget for a room addition?Room addition costs in San Jose depend on several factors based on size, complexity, and finish level. A modest bedroom addition might begin at $150,000–$200,000, while second-story builds can run significantly higher. During your planning session, we provide a detailed estimate specific to your project.
How many months does a room addition project take?The average home addition project spans four to eight months from permit approval to final inspection. Custom or specialty additions may take longer. Getting permits through often accounts for a noticeable share of that overall timeline.
Are permits required for home additions?Yes, absolutely — any room addition that expands your home's footprint requires permits from the city in San Jose. Skipping permits lead to costly legal and financial consequences. Our team manages every filing so you don't have to worry about it.
How does an addition differ from remodeling?A home addition physically expands your home's total square footage by building new rooms outside the existing floor plan. A renovation stays inside the existing footprint without changing the exterior dimensions. Room additions generally involve more complex construction than a standard remodel.
Can you blend the addition with the existing home style?Matching the existing home is a central focus on every room addition we take on. Our team matches finishes and architectural details to mirror your current exterior. The result is an addition that looks cohesive rather than obviously added later.
