A home expansion allows you to increase usable space without moving to a new property. At KGA Construction, we plan and build additions that meet your functional needs while matching your home’s style and structural requirements. We begin with an in depth evaluation of your home to determine where expansion is most beneficial. Our team develops layout options, design concepts, and construction plans that ensure your new addition feels natural and fully integrated.
We handle framing, roofing, insulation, plumbing, electrical, HVAC adjustments, windows, doors, flooring, and finish work. All expansions follow Sacramento County permitting and safety requirements to ensure structural integrity and long term durability.
