I have driven down Elizabeth and Canal on my way to work/downtown/library for 12 years and never noticed the houses are identical. I have noticed and admired both frequently during that time. Funny it took photos on Endangered Durham to highlight the similarities.
I should clarify that 405 Elizabeth is identical to 309 Canal.
There's another one on Gray.
I love the witch hat houses in my neighborhood.
Mr. Johnny Harris lives in the one on Elizabeth St. He is a former cook at the Washington Duke (downtown location) and still spry at 78 years.
I realy like the gargoyles/owls on the Gray house, but the Elizabeth St + Canal St houses are just dramatic as they are like nothing else in the +/-3 block area that is remarkably similar (Triple A, bungalow, queen ann, Rent Man Infill)
I added the one on Gray after the fact - here. I'd hoped to get by to take a picture, but didn't.
Find this spot on a Google Map.
