 More than 300 new homes have been approved in part of Loudoun County in Brambleton. A few dozen of them will meet the definition of affordable. County supervisors recently approved an application to rezone 80 acres of land near Ryan Road and Evergreen Mills Road. All told, there would be 307 single-family detached homes built there. Almost 40 are planned to be cottage lots, as they're called. At 35 feet wide, they're designed to be affordable housing units. Part of Ryan Road will be widened to add turn lanes to this project.
