An addition that nearly doubled the size of this Hinsdale home required detailed research to match the stone work enveloping the exterior. A secondary garage off the side of the home features space for an antique auto aficionado to house his collection. Light spills gloriously into a great room that houses to the couple’s art collection and heirloom piano. Laser cut marble adorns a sleek white fireplace surrounded by windows that stretch to the ceiling. A wet bar provides extra seating and ensures that guests are never far from drink refills.
