This house, at 3022 Wyoming, has always fascinated me. Now, after doing some research, it intrigues me even more. City records state that the Mansard roofed house, which sits all the way on the alley line, allowing for a huge front yard, was built in 1858. It appears on Compton and Dry, so it is at least from 1875 or earlier. But what is even more interesting is that it has a flounder addition to the east, which city records state was built in 1868.
Compton and Dry frustratingly shows the house from the back, but the addition is clearly visible, and there is the slightest intimation of a Mansard roof on the front. I suspect, if the house really is from 1858, that the roof, which did not really become popular in St. Louis until after the war, was added in the 1870s. Therefore, the central hall house was a much older farmhouse.

Additionally, the original house and addition have been separated into two parcels, with two different owners! And while this Sanborn map shows the property in 1903, city records show in that year that a house was built on the front of the property with the flounder addition. So interesting!
