It was a beautiful day to explore New Mark Commons, the exceptionally well-designed mid-century neighborhood west of downtown Rockville. Hosted by Peerless Rockville, a standing-room only crowd of about 60 people gathered in the Clubhouse to hear an illustrated lecture by Dr. Isabel Gournay of the University of Maryland. Rose Krasnow, a longtime resident and former administrator of New Mark Commons, provided the introductory remarks. Afterwards, about half the group walked the neighborhood to visit a single-family house on Radburn and a townhouse on the lake–plus a surprise invitation to visit a second townhouse. Two more neighborhoods will be visited in the next month–the Americana Centre and King Farm–so if you’d like architecture and local history, these are a perfect way to enjoy both.
