Whether you're ready to build a new bedroom, a expanded living area, or a guest suite, room additions are the answer.
Home additions are considered the most meaningful investments a homeowner can make.

What Home Addition Work Involves
Room additions are a broad category that involve everything from constructing a new bathroom to large-scale family room builds. At their foundation, room additions involve expanding your home's footprint — either upward. This is different than remodeling, which reconfigures the current square footage.
These undertakings require a coordinated effort that brings together architectural planning, permit acquisition, foundation work, rough construction, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions touch so many systems, hiring a skilled construction team who can oversee every step is critical.
Room additions are commonly chosen by homeowners who have outgrown their current layout but want to keep their current property. They're often the right move for multigenerational households. No matter the size, the work follows a clear set of phases that we have refined over many years.

Common Questions About Room Additions

What does a room addition cost?Room addition pricing 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 exceed $400,000 or more. During your consultation, we give you a clear breakdown specific to your goals.
What's the typical timeline for room additions?A typical room addition build runs approximately four to ten months from permit approval to final inspection.

How does an addition differ from remodeling?A home addition adds to your home's overall footprint by building new rooms outside the existing floor plan. A remodel stays inside your current square footage without adding new area. Room additions are typically more extensive construction than finish upgrades.
Can you blend the addition with the existing home style?Blending new construction with the original structure is one of our core goals on every room addition project. Our builders carefully selects structural elements and surface materials to complement your home's existing style. Our goal is an addition that appears original rather than tacked on as an afterthought.
