I've seen you've posted a few questions here on Trulia about industrial/commercial property. Email me directly a bit more about your real estate needs and I'll see what I can do to help make it happen. I work with buyers at no extra cost, so I'd love to help you!
You would probably find a building like that in the historic area of the towns surrounding Charlotte, ie. historic Gastonia, Concord, Cornelius, Mooresville, Monroe, Lincolnton, Matthews, Statesville, Rock Hill. You might speak to some architects to see if they know of a building to renovate. Allison Pell renovated two such buildings in historic Gastonia.
Petra, you could also look along the rail lines in Mecklenburg county. There are many interesting buildings near railroad tracks.
A commercial real estate broker could help you locate the right building. I suggest calling Karen Tovar at Keller Williams Realty, 704-892-5518.
Wishing you success,
