Greenbelt Knoll

Greenbelt Knoll is a residential district of eighteen one-story single-family homes arranged in a cul-de-sac on Longford Street. The homes are surrounded by dense trees of Pennypack Park on three sides and feature a unified architectural approach designed in the mid-20th century.

The development was built between 1952 and 1957 by Morris Milgram as Philadelphia's first planned racially integrated residential neighborhood. It deliberately established quotas for residents of different backgrounds, pioneering integrated housing in the city.

The neighborhood attracted prominent residents including Congressman Robert N.C. Nix Sr., playwright Charles Fuller, and civil rights activist Reverend Leon Sullivan. These figures shaped the area through their contributions to society and helped establish it as a place of local importance.

The neighborhood preserves its original Modernist design by architects Montgomery and Bishop, with seventeen houses recognized as protected buildings in the historic district. The compact setting surrounded by parks makes the area easy to explore on foot and offers a quiet surroundings experience.

The development received multiple design awards, including recognition from the American Institute of Architects and Better Homes and Gardens for its innovative residential planning. These early honors show how groundbreaking its approach was for the time.
