Your Garage Conversion Experts in Bell County, TX

Most garages in Bell County are wasting space that could change how your family lives. We’ve turned over 20 garages into actual rooms that people use daily, and the homeowners always tell us they should’ve done it years earlier. A garage-to-living-space conversion makes sense when you consider you’ve already got the structure, the foundation, and usually the electrical hookup. You’re not building from scratch here.

The thing about a garage-to-bedroom or garage-to-office conversion is that it gives you flexibility without the headache of a full addition. Need a teenager’s bedroom that’s separate from the main house? Done. Want a garage-to-master-suite conversion because your current bedroom feels cramped? We handle that too. And if you’re thinking about rental income, a garage-to-ADU conversion can actually pay for itself over time.

We’re licensed and insured, which matters when you’re dealing with permits and inspections. Bell County has specific codes that vary by city, and we know them by heart. Our 5-year workmanship warranty means we stand behind every project long after we’ve cleaned up and left your property.

Exceeded expectations. We are so impressed with the final outcome of the project. The team is timely and they were dedicated to meeting timelines without rushing. 

Their attention to detail is phenomenal and you cannot tell the renovation was not part of the original house.

Quality is job number one and they only use name brand products so that you don’t have to worry about inconsistencies. I highly recommend Gill Construction for any construction needs you have.

Your Investment and Your Timeline

We know construction projects feel like they could spiral in two directions: over budget and past deadline. Here’s how we handle both concerns so you can actually sleep at night during your remodeling project.

Budget

Let’s say you’re spending $50,000 on a garage-to-living-space conversion that adds a bedroom and a bathroom. If you use that new space for the next 20 years, you’re paying about $6.85 a day for a functional room that increases your property value and improves your family’s quality of life. Plus, if you’re converting a garage to an ADU, rental income can offset the investment within a few years.

Timeline

Most of our garage conversions take 6 to 10 weeks, depending on complexity. We’re not going to lie and say nothing ever delays a project, because sometimes the city takes longer with permits, or we find an issue once we open up walls. But we stick to our schedule about 95% of the time. We keep your home clean, we respect your space, and we communicate if anything changes. You’ll know what’s happening every step of the way.

Common Questions About Garage Conversion in Bell County, TX

Yes, you’ll need building permits, and possibly electrical and plumbing permits depending on your project scope. The good news is we handle all of that for you. Each city in Bell County has slightly different requirements, whether you’re in Killeen, Temple, Belton, or Harker Heights. We schedule inspections at various stages and make sure everything meets code. Trying to skip permits might save money upfront, but it’ll hurt you when you try to sell your house or if the city finds out.
Most garage conversions take between 6 and 10 weeks from start to finish. A simple garage-to-office conversion without plumbing might take closer to 6 weeks. A garage-to-apartment conversion with a full bathroom and kitchenette usually takes closer to 10 weeks. Permit approval can add time on the front end, but once we start construction, we keep moving.
It’s actually the opposite! Adding a functional living space typically increases your property value more than the cost of the renovation. A garage-to-ADU or garage-to-guest-house conversion can be especially valuable if it’s rentable. The only exception is if you live in a neighborhood where everyone parks in their garage, and you’re the only one without parking. But in Bell County, most driveways can fit multiple vehicles anyway.
Absolutely. A single-car garage is usually around 200 square feet, which is plenty for a home office, a bedroom, or even a small studio apartment. We’ve done garage-to-room conversions in single-car garages that turned out beautifully. The key is smart design and maximizing your space with built-in storage and multi-functional furniture. You won’t have room for a king bed and a walk-in closet, but you’ll have a comfortable, usable new room.
