561 Walnut Ave

From the National Register nomination

Two-story Foursquare-form house of stretcher brick-veneer frame construction with an asphalt-shingled hip roof with a hipped dormer and side gable. The one-story front porch has classical wood columns and square-section balusters. Other features include a poured-concrete foundation, a front entry with transom and sidelights, 8/1 windows, and a one-story rear wing with porch. A poured-concrete retaining wall extends across the front of the lot and a stone one across the south side. Descending from the sidewalk to the street are steps fashioned from various dressed stones--limestone, granite, and brownstone--and one of concrete. This house and its twin next door at 553 Walnut are labeled "from plans" on the 1913 Sanborn map.
