For five years beginning in 1953, Washington’s own modernist Charles M. Goodman served for as a consulting architect for Lafayette, Ind.-based National Homes, which was the country’s largest prefab home manufacturer. On Sept. 23, you can tour Highland Hills in Richmond, the only neighborhood in central Virginia exclusively consisting of mid-century homes. Located in Bon Air in Chesterfield County, the 80 or so homes in Highland Hills were developed in the mid-fifties by National Homes and featured the designs of Goodman. The tour is being organized by Modern Richmond. The event, which runs 12 pm to 4 pm, is free but a $20 donation is suggested. Reserve your free tickets here.
