I've probably mentioned once or twice that I work for a non-profit affordable housing builder. Our construction offices are located in the Portland neighborhood in Louisville, which has a lot of late-19th century buildings, some of which have been well-maintained, and others not so much. Just south of the Portland neighborhood is the Russell neighborhood, which has plenty of old buildings too. One that I see on a regular basis is the old Ouerbacker house, which was the home of a coffee merchant and is now in an advanced state of decay.
I think it would make a lovely B&B, if only the preservation group which owns it could raise the funds to restore it. They could renovate the carriage house as a residence - it's surely as big as the house I live in. Anyway, I don't have much information on the house, but I took lots of pictures, which you can view without commentary from me. I love old buildings and I hope this one can be saved.
