Home Additions in Georgetown, TX
Georgetown is growing fast, and homeowners here understand that building up or building out makes more sense than selling and starting over somewhere new.
What the Home Addition Process in Georgetown Looks Like
A well-executed addition integrates so naturally that visitors assume it was always part of the original plan.
Whether it’s a guest suite that flows off the main hallway or the sunroom that catches afternoon light, it should be built to the same standard as the rest of the house. That’s always our goal.

Carol Harris
We have been dreaming of adding a big shady porch on the back of our house for a while, and Gill Construction gave us everything we wanted in our new space. They were very easy to work with, on time with the various aspects of the project and very responsive to our requests and questions.
We are extremely pleased with the quality of the construction and highly recommend Steven and his crew. We love it !

We hired Gill Construction to demo and rebuild our back brick wall, and we’re beyond impressed with the results. It looks like nothing ever happened—no debris, no mess, just clean, solid work.
They also remodeled our bathroom, and it’s hands down the nicest part of our home now.
High-quality craftsmanship, attention to detail, and super professional throughout. Highly recommend!

Home Addition Questions We Hear From Georgetown Homeowners
Yes. The City of Georgetown requires building permits for additions, and inspections are required at key stages. We manage the entire permitting process so you do not have to navigate it yourself.
Most additions run 8-16 weeks once construction starts. The actual timeline depends on size, structural complexity, and any material lead times. We build a schedule specific to your project before work begins.
