Construction with Transparent Communication

From the foundation to the final nail, our team delivers craftsmanship and clarity. You’ll receive regular updates and walkthroughs to stay informed and confident throughout the process.

Frequently Asked Questions About Room Additions in Sunnyvale

The duration of a room addition in Sunnyvale can vary significantly, but generally ranges from 2 to 6 months from initial planning to final completion.

Yes, almost certainly. Any significant structural change, increase in square footage, or alteration to the footprint of your home, such as a room addition, will require a building permit from the City of Sunnyvale. This also includes any new plumbing, electrical, or mechanical work that is part of the addition.

Absolutely, achieving a seamless match with your existing home’s architecture, materials, and finishes is a cornerstone of our design philosophy at King David Home Builders. Our goal is for your new room addition to look and feel like it was always a part of your San Jose home, not an obvious add-on.

While new materials will inherently have a “fresh” look compared to weathered existing ones, our aim is to select materials that are known for their consistent aging properties. We also discuss maintenance considerations with you to ensure your entire home continues to look its best over time. Our goal is for the aesthetic difference to diminish as the new materials settle and age naturally.

Yes. We provide full in-house architectural and design services, including 3D renderings, so you can visualize your new space before construction begins.
