55-57 East 75th Street, ca. 1911.

Nos. 55 and 57 were both constructed in 1881-82 by architect John Prague. Both building have been renovated in the 20th century. In the late 1930s, the building on the left (no. 55) was renovated into brick front neo-Federalist style building that can be seen today. No. 57 had a much more dramatic facelift later in the century. In 1979 architect William Glickman completed a new Brutalist facade for the building, with angled concrete and projecting balconies on the second and third floors. The now nine-story building towers over its neighbors.

The writers of the AIA Guide to NYC say this, " a curious former row house transformed into an early "sliver building. As an object it is abstractly handsome. As a citizen of the block it's inciting a riot."
