Still time to customize finishes! Currently undergoing a major expansion to add a new primary bedroom suite, family room and exercise room across three levels, this spectacular residence offers it all. The stone mansion, appropriately named "Appin", is a residence of historic significance built by John Stewart Jr. and situated on one of the most prestigious streets in Short Hills. Sports enthusiasts will enjoy one of only a few residential indoor squash courts in the US as well as outdoor tennis, basketball, swimming and plenty of room for football and soccer. The 2.3 acre property is framed by sprawling lush flat lawns, stone terraces, a 4-car over-sized garage and pool house with kitchen, full bath and laundry. The impressive formal rooms offer lofty ceilings, striking millwork and a soaring staircase.
