Members of the city Historical Commission got what they wanted Monday, when an Exton company agreed to further change its plan to redevelop the former Lancaster YMCA site by saving â not razing â two historic buildings there, not just one. The Hankin Groupâs concession was the third significant change to its original plan to construct up to 250 apartments, a 440-space parking garage, a 30,000-square-foot medical office building and small retail spaces there. Commission members praised Hankinâs conceptual redesign of its plan as âbrilliant,â âa successful solutionâ and âvery creative.â The commission did not vote on the preliminary redesign; it will vote when Hankin returns in two or three months with a final plan.
