NYC Facades

I have trouble identifying the style on this building. Is it historicist?

Three beautiful townhouses

I happened past these town houses and was simply awestruck.Their curb appeal is immense; set back, architecturally unique, well-kept. The whole block is something else. (See a mention of the style of this area in this article linked also from the St. Luke’s Church page.)

How did it come to pass that Harlem has the best single family home architecture? What architectural style are these in, anyway?
