Calder Flats in 11th Street

At nearly the same time in 1899 that William M. Calder filed plans for three mixed-use buildings in 7th Avenue, he also filed plans for five small apartment houses on the adjacent plots in 11th Street, south side, east of 7th Avenue:

And in fact the apartment buildings are still there, unchanged since they were erected in 1899. Apologies for the rather poor quality of the photograph, but it is possible to make out the five 8-family "double flat" buildings, just beyond the building at the southeast corner of 11th Street and 7th Avenue, also by Calder and reviewed in our last post.

The photograph below shows the easternmost two of the row of 5 matching flat houses:

Calder apparently gained control of a large parcel of property on the south side of 11th Street, east of 7th Avenue, and developed it all at about the same time: apartment houses on the side street, and mixed-use (flats over stores) on the corner and facing 7th Avenue.

Further confirmation that these 11th Street buildings were constructed by Calder is found in the Brooklyn Eagle of January 31, 1903. The photograph is of some buildings in 12th Street designed by architect Thomas Bennett for William Calder in 1901. But the photograph's caption reads, in part:

About two years ago [William Calder] sold five fine flat houses on Eleventh street, near Seventh avenue, to William Dick, the sugar refiner, for $75,000 cash.
