Working with Triangle Bar Group was a wonderful experience. I am truly thankful I called for their services. They are not only professional at what they do but also reliable and dependable. I’ve had my master bathroom remodeled and they offered me a very reasonable quote, and the end result exceeded my expectations.  Highly recommended.

Triangle Bar Group designed and built our new ADU and did an amazing job. The quality was beyond what we expected.  Allen and Angie were great to work with, and very professional. There were several trades involved in the overall construction and work was very well coordinated and kept the work flowing. Allen was able to work with us on our budget by providing us with great options. We would definitely recommend them as an great ADU Builder in Portland.

Angie came up with a wonderful design for my bathrooms. Always willing to answer my questions or make a recommendation even after the work was completed. Would definitely use Triangle Bar Group for any home design or improvements.
