What People Are Saying...

“We have asked Duffin Design Build to help us on a variety of projects at our home. Teresa never refused an opportunity to help us out, no matter how small our needs were. The largest project she tackled for us was our remodel in July 2015. It involved a rip-and-replace of our kitchen and master bathroom, new flooring throughout the ground floor, new trim everywhere, new paint, new fixtures, and plenty more. The project totaled around $170,000. She brought an amazing team of subcontractors, and her project manager was impeccable. Brian was always very prompt with responding to our questions and sending us updates during the project, including some terrific photos. We enjoyed collaborating with Teresa on our ideas and taking her input as well. We regret that we are moving too far away for her to be the contractor on our new home build. She would have been our go-to person, without question. She has our unqualified recommendation for any project you may be contemplating”.

“After tiring ourselves out with DIY and disappointment in big box store service and installation, my husband and I knew we wanted professional help with our home renovation projects. We went to Teresa Duffin of Duffin Design Build and we are so glad we did! Personal service, professionalism, skilled and efficient craftsmen, reasonable cost, and timely completion! On our first project, the unique challenges were solved and resulted in an excellent outcome, so now we are now happy repeat customers and will certainly to continue to rely on the Duffin team to keep our home in great shape and looking special”.

“Truly a quality builder/remodeler. Teresa has remodeled several homes for us and without a doubt, the value added more than covered the remodeling. She listens, advises, manages and provides a true value”.

“We had a 30 X 40 metal shop built with a small living area inside.  Duffin Design Build far exceeded our expectation.  Quality of work done in a timely manner for a fair price.  I especially enjoyed working with Teresa.  She is professional, honest and very concerned with understanding exactly what we wanted.  We also worked with her assistant, Brian, who was helpful at every step along the way.  Every single contractor she sent out was well qualified and a joy to work with.  The work site was  kept clean and free of debris which was an added bonus.  We will be calling on her again when we are ready to build our house.  I highly recommend her work”.

“We bought a new home that Duffin Design Build built.  Our home is a dream and we are very particular being that my husband had built several luxury hotels.  The attention to details and finishes are beyond fabulous.  As long as we live in Texas we will only buy or build with Duffin Design Build; not that we are planning to ever leave our current gorgeous home”.

"Teresa is one great custom home builder. (Yes she is a Woman but that is not a negative, she has a pedigree in custom homes.) Her attention to detail and perfection is top notch. My wife and I have built two homes and we are still married thanks to Teresa’s attentiveness. She is a listener, and idea builder, a problem solver who only builds solid, energy efficient, beautiful homes. I can’t think of one artisan sub-contractor that I would replace if we were doing it again. Everyone that sees the home is amazed with the design and beautiful finishes. Every detail has to be perfect for Teresa. We went with rain water collection for which I wanted to custom handle the elimination water for wildlife. She found the guy. I drew the plans and he build it. First class job.

This young lady is not only a high quality home builder she has become a dear friend”.

“Teresa’s attention to detail combined with her knowledge of the business and the quality of her construction, cabinet, painting and trim sub-contractors was outstanding.”

“We had a wonderful experience with Teresa and Duffin Design Build. Teresa’s team went above and beyond our expectations. We hired them to finish out a room and were so pleased with their work, we continue to find projects for them. Teresa impressed us with her knowledge, professionalism, honesty and communication skills. Her prices were very competitive. We’ve worked with numerous builders over the years and Duffin Design Build was by far the most pleasant experience. We highly recommend them.”

“Working with Teresa Duffin and her folds has been successful and collaborative, with candor, and requisite humor.  The quality of work has ben first rate and we have received many complements on our new home.  The project was difficult as the home was build on 175 acres of fully raw land, requiring over 1 mile of power poles, rainwater capture, septic systems, brush removal….Teresa was always ready to hear additional requests or modifications to the work, and she made sure that what was supposed to be done got done.  We have never built a house before and we would not build another one without her help”.

”We had our flooring replaced and our bathroom fixtures updated and we were very pleased with the outcome and the cleanup!  Would hire Teresa again!  Highly recommend!”


Austin, TX

“We hired Teresa after working with three other builders/designers to improve our recently purchased property in Dripping Springs.  She made us feel confident and valued as a customer, so we chose to build with Duffin Design Build.  This was our fist time building a custom home, Teresa and her project manager Brian went above and beyond to help this process be as smooth as possible.  When you have an 8 month custom project, some minor or major things can go wrong, but the few minor times we had a problem, Teresa made sure we were 100% satisfied with the outcome immediately.  They were able to work on the fly with challenges and changes (that were mostly something I missed).  This house is SOLID, excellent construction, energy efficient, beautiful floors (hardwood and tile), and overall great feeling to walk through.  I highly recommend Duffin Design Build because she really cares and wants you to enjoy your new home!”

“My son used Teresa Duffin as their home builder in Dripping Springs, Texas.  The house was on a very difficult lot to build, and by far she was the best builder and designer for the property.  She is honest and trustworthy and very detailed.  She works well with her clients and she is easy to reach.  There is detail and quality in every part of the house and property.  My husband was a builder and I am so impressed with her professionalism and her staff and sub contractors.”
