The naturalistic, plant-like carving on the brackets supporting the Italianate door hood gave way to machine-made, geometric incisions around the Neo-Grec doorway and windows. Another Neo-Grec innovation was the full-height, two-sided projecting bay, which allowed larger windows to bring more light into the interior. The Neo-Grec houses below, in Berkeley Place between 6th & 7th Avenues in the Park Slope Historic district, are brick with brownstone trim and were begun in 1886.
