How Much Do Home Additions Cost in Belton, TX
No two additions are the same, which means costs can vary. In Belton, most projects we’ve handled have ranged between $40,000 and $150,000+. A smaller project, like a mudroom or spare room, will be on the lower end, while bigger jobs, such as a second-story addition or a major kitchen expansion, can be much more.
The best way to know for sure is to talk through your specific needs with us. We’ll give you a clear, tailored estimate so you know exactly what to expect.
5 Things That Influence Pricing
- Size of the project – More square footage means more materials and labor.
- Room type – Kitchens and bathrooms run higher because of plumbing, electrical, and finishes.
- Finish quality – Custom cabinets, high-end tile, and premium flooring will add to the cost.
- Changes to the structure – Adjusting foundations or moving walls adds complexity.
- Permits and inspections – Local rules and requirements in Belton can affect both cost and timing.
Fair Pricing & Reliable Timelines
When you plan a home addition in Belton, two things matter most: sticking to the budget and finishing on time. We get that. That’s why at Gill Construction, we map out each stage carefully, keep you in the loop, and build with efficiency and respect for your home.
Think of your addition as an investment in the way you live every day. Spread out over the years you’ll use it, the cost is more manageable than you’d expect, and the comfort it brings is worth it every time you walk through the door.
