Gracie Square
The New York Times has an article on the real estate section today on the history of Gracie Square. The building was built to look from the outside like a set of individual buildings.
What purchasers got on the outside was a single structure so variously adorned that it looked like half a dozen. The Gracie Square side is an interlocking puzzle of vertical runs of quoining, horizontal courses of stone, irregular balconies and oddly placed moldings.
