At Brother & Brother Builders, we focus on helping San Jose, CA homeowners add the square footage they deserve.

What This Type of Project Involves
Room additions encompass many different types of construction that span everything from adding a single bedroom to large-scale family room builds. At their core, room additions mean physically extending your home's footprint — either upward. This is distinct from remodeling, which stays inside the existing walls.
These projects require a full range of trades that involves architectural planning, building permits, foundation work, rough construction, electrical, plumbing, insulation, interior finishing, and final finishes. Because room additions touch so many systems, working with a skilled construction team who can manage all of it is the key to a smooth project.
Room additions are a great fit for homeowners who want a dedicated space but prefer to stay in place. They're frequently selected for homeowners planning to age in place. Regardless of the scope, the work follows a well-defined set of stages that our team have mastered through experience.
