This has been an incredible process. We feel so lucky to have the home that we do and to be in here enjoying it. We know that there aren’t a lot of folks, a lot of friends that have had this opportunity. It’s something that we are so thankful for. We had such a great experience working with Ichijo.

I’m very happy with my Ichijo townhouse. The layout is bright, spacious and efficient. The technology and appliances are modern and work extremely well. The construction is solid, well insulated and shows Ichijo builders are craftsmen.

We absolutely love our Ichijo house! More than that, we appreciate all of the time and effort they put into working with us. We recently purchased the Harrison Court home from it’s previous owners, as we were drawn to it’s exceptional quality, energy-saving construction, and superior design. It is clear the Ichijo teams puts thought into their work and it makes us feel good knowing we can reduce our environmental impact by living in a green home.

When we moved in, the house needed some repairs on the windows and siding. We brought up some questions and concerns with the Ichijo team and they went above and beyond our expectations to get things fixed. They were responsive, communicative, professional, thorough, and extremely generous with their time and resources. My husband and I feel very thankful to have purchased a home built by builders who stand by their quality of work, especially over time.

I am delighted to share my exceptional experience with Ichijo Home Builders. Throughout my initial interaction to the final walkthrough, their commitment to quality and craftsmanship was evident. The fusion of traditional Japanese design principles with modern American comforts created a truly unique and inviting home for my family. The attention to detail, superior materials, and efficient construction process exceeded my expectations. The team’s professionalism, transparency, and unwavering dedication ensured a smooth and stress-free building journey. We own more than one home built by Ichijo. I wholeheartedly recommend Ichijo Home Builders for their outstanding workmanship and personalized service.
