When your living situation evolves and your current home no longer works for everyone, room additions represent an effective path to lasting comfort. At Brother & Brother Builders, we are dedicated to helping San Jose, CA homeowners add the square footage they need. Whether you're dreaming of a new bedroom, a larger kitchen, or a sunroom, room additions are the answer.

What This Type of Project Involves

Room additions encompass many different types of construction that involve everything from constructing a new bathroom to full second-story additions. At their heart, room additions require adding to your home's existing structure — either upward. This is not the same as remodeling, which works within the current square footage.

These undertakings demand a collaborative approach that involves architectural planning, city approvals, foundation work, framing, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions involve multiple building disciplines, choosing a skilled construction team who can manage all of it is the key to a smooth project.

Room additions are commonly chosen by homeowners who want a dedicated space but prefer to stay in place. They're frequently selected for multigenerational households. No matter the size, the approach follows a clear set of steps that our builders have mastered through experience.

A basic square addition might start around $150,000–$200,000, while larger additions can reach well into the six-figure range.

How long does a room addition take to complete?

A typical room addition build runs approximately four to eight months from permit approval to final inspection. Multi-room or second-story additions may take longer. The permit process can take up a significant portion of that total schedule.

Are permits required for home additions?
