KGA Construction specializes in building custom room additions for homeowners in Sacramento, CA who want more space without moving or undergoing a full home expansion. Whether you need an extra bedroom, a larger living area, a new workspace, or a private guest room, we design and construct room additions that match your home’s style and structure.
Our additions look natural, feel comfortable, and provide long term value.
A well designed room addition gives you the extra space you need while maintaining the look and feel of your existing home. At KGA Construction, we handle every part of the process from planning to finish work.
We begin by evaluating your home’s structure, available space, layout flow, and your goals for the new room. From there, we design a custom addition fully integrated with your home’s architecture and interior style.
We complete framing, roofing, insulation, drywall, flooring, windows, doors, HVAC adjustments, electrical, plumbing (if needed), and interior finishing. Every addition is built to align with Sacramento County building requirements. Whether you need extra space for family, work, or comfort, our team builds rooms that feel like a natural extension of your home.
Room additions require skilled planning to ensure structural integrity, aesthetic consistency, and long term durability. At KGA Construction, we take a detail driven approach from start to finish.
We ensure your new room matches your home’s roofline, exterior materials, wall textures, flooring styles, lighting design, and interior finishes. Our team communicates clearly throughout the process and ensures your project stays on schedule.
With extensive experience working on homes in Sacramento County, we understand local building codes, zoning requirements, and architectural styles. This allows us to deliver additions that blend seamlessly with your existing home.
