Whether you're ready to build a new bedroom, a larger kitchen, or a sunroom, room additions are the answer.
Home additions represent one of the most valuable investments a homeowner can make.

What Room Additions Involves
Room additions cover a wide range of projects that span everything from building an attached garage to full second-story additions. At their foundation, room additions mean physically extending your home's existing structure — either horizontally or vertically. This is not the same as remodeling, which reconfigures the existing walls.
These builds require a full range of trades that involves architectural planning, permit acquisition, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and final finishes. Because room additions require so many interconnected trades, working with a general contractor who can coordinate each phase is essential.
Room additions are ideal for homeowners who want a dedicated space but want to keep their current property. They're also a popular choice for homeowners planning to age in place. Whether it's a small bump-out or a full-scale addition, the process follows a clear set of stages that we have executed on hundreds of projects.

What Homeowners Ask About Room Additions
Families thinking about room additions typically come to us with the same recurring topics. Below are straightforward responses to the topics that come up most often:
What should I budget for a room addition?Room addition pricing in San Jose range considerably based on what's being built. A modest bedroom 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.
How long does a room addition take to complete?The average home addition project runs approximately four to ten months from start of construction to completion. Larger or more complex additions may take longer. Getting permits through often accounts for a noticeable share of that project length.
Do room additions require permits in San Jose?Always — any room addition that adds square footage requires proper city approval in San Jose. Building without approval lead to serious problems at resale. We handles all permitting so you don't have to worry about it.
Is a room addition the same as a renovation?A new-room build adds to your home's existing size by extending the structure outside the existing floor plan. A renovation stays inside your current square footage without adding new area. Room additions generally involve more extensive construction than finish upgrades.
Can you blend the addition with the existing home style?Achieving visual continuity is one of our core goals on every room addition build. Our builders matches finishes and architectural details to complement your current exterior. The result is an addition that looks cohesive rather than obviously added later.
