America's suburbs are not the homogenous places we sometimes take them for. Today's suburbs are racially, ethnically, and economically diverse, with as many Democratic as Republican voters, a growing population of renters, and rising poverty. The cliche of white picket fences is well past its expiration date.The history of suburbia is equally surprising: American suburbs were once fertile ground for utopian planning, communal living, socially conscious design, and integrated housing. We have forgotten that we built suburbs like these, such as the co-housing commune of Old Economy, Pennsylvania; a tiny-house anarchist community in Piscataway, New Jersey; a government-planned garden city in Greenbelt, Maryland; a racially integrated subdivision (before the Fair Housing Act) in Trevose, Pennsylvania; experimental Modernist enclaves in Lexington, Massachusetts; and the mixed-use, architecturally daring Reston, Virginia.Inside Radical Suburbs you will find blueprints for affordable, walkable, and integrated communities, filled with a range of environmentally sound residential options. Radical Suburbs is a history that will help us remake the future and rethink our assumptions of suburbia.
