Our Happy Clients

Paradigm literally designed the house better than we could have imagined and we feel very lucky to have such a fantastic home. We highly recommend Paradigm!
Everett Family, Fairfax
After careful thought and consideration, we entrusted Paradigm with our home renovation and the build-out of our basement. The Paradigm team’s attention to detail and communication was excellent. They, and their contractors, were respectful and courteous. Paradigm displayed great integrity throughout the project and we would highly recommend them.
Skeen Family, McLean
Best design/build company in the business. Paradigm did a pop top for us in 2014 and finished on time, on budget, with 100% satisfaction. Tim and his team are amazing- they oversee every detail to make sure their clients are happy and feel a part of the process. Over a year later, we are still impressed with the quality and craftsmanship. I would recommend Paradigm to anyone looking to redesign/build. They are EXPERTS in Arlington.
Vaughan Family, Arlington
We had a fantastic experience with Paradigm Building Group! Our project was a complete gut-renovation and a 1,300SF addition. From the initial walkthrough, to getting a design on paper, budgeting, scheduling and construction it was a great process. We are familiar with the building industry and Paradigm was extremely professional, transparent with pricing and schedules and their project manager was extremely helpful, cared about the project and the quality of his subcontractors. They know the residential market, the building codes and permitting processes very well which was a huge help. We highly recommend Paradigm Building Group!
Gallardo Family, Arlington
Paradigm built a custom home for us on Lake Thoreau in Reston in 2012. We could not be more pleased with the home or the experience working with Paradigm. Work was completed on time and on budget – we were able to move in 9 months after the start of construction. Paradigm also did a great job following up with small issues after we moved in. We recommend Paradigm unequivocally!
Lendman Family, Reston
Tim and his entire team at Paradigm Group build a beautiful home. They are lead with heart and deeply care about the home they are building for their clients. It’s been a true pleasure working with them over the years. Two thumbs up!
Rob Chevez, Caza Realty Group
If you’re going to renovate, I highly recommend Paradigm Building Group. They are transparent, honest, and accommodating. Don’t get fooled with the one-man owner/builders with lower quotes. In the end you will pay more than what it would have cost you with Paradigm.
Kim Family, Great Falls
We are so pleased with our home renovation! Working with Paradigm was a professional, collaborative and rewarding experience. Their family roots extend to the way they treat their clients.
Schroeder Family, Falls Church
Paradigm Building Group completed our custom home on time and on budget. They provided excellent communication about progress, involved our input in all phases and were always 100% honest and reliable. They went out of their way to make sure we got the home we wanted.
Nasir Family, Fairfax
As a local community lender with years of construction lending experience, I am privileged to work with Paradigm Building Group and their clients. Paradigm is amongst the area’s elite custom home builders, providing exceptional quality and service to individuals who are seeking the utmost in new home construction. I would recommend Tim and his team to anyone looking to build their dream home. From architectural design to post construction support, Paradigm is considered in my book to be exceptional.
Mark Ferguson, Residential Construction Lender
We have thoroughly enjoyed cultivating a partnership with Tim and his team at Paradigm Building Group. Their excitement and compassion shine through in their work, evident by the collection of happy clients and exquisite homes we share together. In each project, throughout the entire lifecycle of design and construction, Paradigm has demonstrated their ability to build trust and dependability with homeowners. They are thoughtful listeners and communicators – consistently exceeding the expectations of their clients with beautifully crafted homes.
