Professional Home Addition Contractors in Austin

More space. Better layout. Built to match your home.

A home addition in Austin requires careful planning, structural work, and coordination with existing construction. The goal is not just adding space, but making the new area feel like it has always been part of the home. Our team works with homeowners who want to add bedrooms, expand living rooms, build home offices, or create guest suites. Every room addition begins with evaluating the current structure, foundation, utilities, and roofline so the new construction integrates properly with the existing home.

Austin homes often sit on slab foundations and require careful structural planning for expansions. Our home addition contractors focus on proper framing, roof connection, insulation, and exterior finishing so the addition looks seamless and performs well over time.

Homeowners also appreciate having clear information about home addition cost before construction begins. We explain the scope of work, timeline, and materials so you understand exactly how the project will move forward.

James Riley

This company did major renovations on our house. It was necessary to completely replace all the old carpentry, redo the ceilings and floors, wallpaper, install underfloor heating in the hallway, bathroom and kitchen, lay new tiles, which I, incidentally, first bought myself and put a decent amount of money on it. Then the company offered to help me in the selection of materials, which significantly reduced the financial and time costs. In general, I can say I was satisfied with the quality of repair and service. Thank you very much!

Jeff Breddy

I am a busy man, constantly at work, so it was important to find a company that is responsible for the tasks. I simply had no time to monitor all the time. Now that all the repairs are completed, I can say the following: the professionals are really smart and took the assigned tasks very seriously. Personally I had some difficulties with the concept of design, but THA Construction LLC designer was able to pick up a lot of interesting solutions, and I was still decided. The work was done quickly and of a very high quality. The company is decent and I am happy.

Sarah

Made a design for the apartment and repairs. There was an apartment of the old layout, secondary in a terrible condition. Got the keys to the apartment ready to move in with designer renovation, everything as in the approved project. I was very satisfied! With the price and deadlines are exactly!

Michael Wade

I ordered house restoration. I chose them on the advice of my neighbors, I’ve seen their work in person. They work fast, on the money all exactly as agreed in the beginning. They don’t ask for a deposit, payment is based on what they’ve done.

Steven

I was also pleased with the work of the company’s employees. I’ve never seen such a well-coordinated and positive team. They chose and made me a repair, based on the amount I indicated. Despite the low budget, it looks expensive and rich, just super. Answers to questions clearly, quickly, with explanations. It was obvious that the company employs true professionals.

Garry

I needed an interesting kitchen design. My wife saw something like this when she was visiting relatives, we were advised this company. The staff at THA Construction LLC really grasped exactly what we needed and managed to translate it into the interior. Our kitchen is now the most beautiful place in the whole house.

I can’t recommend THA enough as they are to saviors I had a flood in my kitchen and they helped us to reconstruct full house which involved kitchen / flooring and two bathrooms. Vadim , our Project Manager was helping us with all the issues that we had with the insurance during the process. I can’t recommend them enough as they saved our house and now we’re gonna have a Christmas in a fully reconstructed house. Thanks THA !!

I recently hired THA Construction & Remodeling in Austin, Texas to remodel my pantry and laundry room, and the experience was exceptional from start to finish. Alex and Victoria were amazing!From first appointment till the end. They helped me to choose finishes and were very patient!
Their team installed custom black and walnut cabinetry, along with beautiful leathered quartzite countertops and a marble backsplash that completely transformed the space.
Not only was the craftsmanship top-tier, but the crew was incredibly friendly, professional, and easy to work with throughout the entire process. They communicated clearly, stayed on schedule, and delivered exactly what they promised—high-quality work with stunning results.
If you’re looking for a reliable remodeling company in Austin that specializes in custom cabinetry, high-end finishes, and detailed craftsmanship, I highly recommend THA Construction & Remodeling. My pantry and laundry room have never looked better!

Seriously, I can't recommend THA Construction enough! The entire experience, from that first consultation to the final walk-through, was absolutely outstanding.
The quality of their workmanship and attention to detail is an easy 5 stars. You can truly feel the difference their commitment to European quality materials makes, and their unique designs resulted in a space with real character.

We reached out to THA Construction for a shower remodel. This was our first large remodel project as homeowners and right away we knew Alex and Victoria were who we wanted to work with. They were both so friendly, responsive, and supportive with all of our questions and concerns. We also have to shout out Vadim who did the demo and tile work for the shower, he was amazing.
The shower looks amazing and adds so much to our house, we look forward to working with THA for any projects in the future!

We loved working with THA Construction this summer on our primary bathroom. Alex and Victoria were both great and provided a lot of insight to help us make decisions for our bathroom renovation. They understood our vision, worked with the smaller space we had, and made everything we wanted a reality. Cesar and his team did great work as well! We could not be happier with the final product. Highly recommend using them for your home projects!

We had a great experience with THA remodeling two full bathrooms in our home. They were helpful in the design process, had great communication and were very responsive throughout the project, and were pretty spot on with their timing estimation. The crew that was in our house was tidy and respectful, which was great since I work from home. I would definitely recommend them to anyone and would absolutely work with them again!
