Bought it from 5 Star Metal Buildings. It is 24x30, I wish I went just a little bit bigger. Although I did over size it just not enough. I got a hold of a local rep from a family member that got one from them prior. I did most the work thru the rep, sizing and all. the back log was about 2 months but seems like that is normal now, I think the demand for them went up. When it was installed there was a crew that did the work. www.fivestarmetalbuildings.com/
