We've been serving the riverbend area for 31 years from the same location, with the same great Diamond Buildings LLC amish built portable buildings. The dealership was first started as a storage lot for Diamond Buildings LLC, back in 1995. Richard K started selling the buildings for the manufacturer. Dave B. Took the business over in around 2010. I (Ryan T) took the business over in January of 2019, and have developed countless relationships with so many good people in my time so far, and developed the business into what it is today. I firmly believe in the quality of the product, the affordable prices we offer the buildings for, and stand behind the good people at Diamond Buildings LLC. We strive to provide the best quality portable buildings, at the best prices, and the highest level of customer service and care possible. When you purchase a Diamond Building, you're not a customer, you become a member of the Diamond Buildings family. Thank you for trusting us with this important purchase for 31 years.
