Whether you're planning for a new bedroom, a larger kitchen, or a dedicated workspace, room additions are the answer.

What This Type of Project Involves
Room additions cover a wide range of projects that involve everything from building an attached garage to major kitchen expansions. At their heart, room additions require adding to your home's footprint — either upward. This is different than remodeling, which works within the original layout.
These projects demand a collaborative approach that combines architectural planning, permit acquisition, foundation work, structural carpentry, 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.

What should I budget for a room addition?Room addition investment levels in San Jose vary widely based on what's being built. A basic square addition might begin at $150,000–$200,000, while complex custom expansions can reach well into the six-figure range. During your initial meeting, we give you a clear breakdown specific to what you're planning.
What's the typical timeline for room additions?Most room additions runs approximately four to ten months from start of construction to completion. Multi-room or second-story additions sometimes push past a year. The permit process can take up a noticeable share of that overall timeline.

Unpermitted additions can result in costly legal and financial consequences. Our builders handles all permitting so nothing falls through the cracks.
What's the difference between a room addition and a home remodel?A room addition physically expands your home's existing size by building new rooms outward or upward. A interior update stays inside your current square footage without adding new area. Room additions are typically more extensive construction than a standard remodel.
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 builders carefully selects exterior materials, rooflines, siding, and trim to complement your home's existing style. Our goal is an addition that appears original rather than tacked on as an afterthought.
