I am going to disagree with jharkin, to some extent(sorry) a Greek Revival does not HAVE to have the gable end to the front. It may, but I can think of some notable exables that DO NOT. That may be a somewhat regional difference. But at least here in the South there is no guarantee of that being the case. Obviously this is a simple version of whatever style it is.
Is this the same house with the beaded beams? If it is, I would start to wonder if it might not be older than we are thinking. Check those beams to see if they are hand planed. Don't look it, but I would be curious about that. Never seen them used on later houses, except a few high style Victorian to 20's houses trying to appear older than they were.
