Neighborhood units, greenways, modernist center
Influential UK new town prototype
Frederick Gibberd's Harlow (begun 1947) was a flagship British New Town built under the postwar programme to absorb London's overspill, organized into self-contained neighbourhoods clustered into districts around a central town centre, separated by green wedges, with pioneering pedestrian precincts and cycle paths.
Harlow exemplifies the British New Towns movement — the most ambitious state programme ever to realize garden-city ideals, building dozens of planned communities to rehouse millions and decentralize the metropolis.
Largely realised: Gibberd's master plan structured the town's development, delivering neighbourhood units, green wedges and a modernist centre, with The Lawn (1951) the UK's first residential point block. It continues to grow under the Harlow and Gilston Garden Town.
Critics note that Gibberd's dispersed neighbourhood-unit layout and generous green wedges produced low residential densities and car-dependent separation that diluted urbanity.
