(RECAP: After several years of on-again, off-again plans for redevelopment, Lake Anne Fellowship House has a signed agreement to build a new affordable senior housing complex. The Fellowship Square Foundation (FSF), which operates the Lake Anne buildings, the facility at Hunters Woods Village Center, and several others in the Washington, DC area, says it has a signed deal with the Community Preservation and Development Corporation (CPDC) for a new building to replace the aging structures at 11480-11450 North Shore Drive in Reston. The new construction project will replace all 240 apartment units, built in the early 1970s, with “a new, state of the art facility.” CPDC is a non-profit developer of affordable housing.)
