Brownstone basement garden; Or, the double staircase that isn't: 23 East 11th Street (1844), Greenwich Village, New York
I like the illusion of a grand double staircase, but, in fact, the "basement" garden and cast iron balcony belong to No. 23, the house whose steps and entrance are on the right. The effect is created in part by the use of identical ironwork on the staircase of No. 21, on the left. There is a very narrow space, unnoticeable in the photo, between that staircase and the balcony next door.
The row of brick-fronted Greek Revival houses with brownstone basements was built in 1844, as affluent society spread up Fifth Avenue and its side streets north of Washington Square. Initially a private mansion, No. 23 was for half a century the Free Home for Destitute Girls. The interesting story of the house and its occupants can be found here: daytoninmanhattan.blogspot.com/2013/08/the-1844-walsh-hou....
This house was very handsomely restored as a single-family home in 2012
