Never before listed, duplex penthouse with over seven thousand square feet of luxe living space, conceived by Dwayne MacEwen of DMAC Architecture & Interiors, under the artful eye and keen collaboration of its original owners. Unobstructed views of the city are revealed from every room in the home. Built from the ground up to suit city living with a penchant for gracious entertaining, unmatched privacy and two thousand plus square feet of unparalleled terraces that boast exquisite northern, southern and eastern views. This quiet neighborhood pocket is nestled in between the hustle and bustle of city living, floating high above the fray in a full-service luxury doorman building. The marble "stair concept" invites a dramatic entrance. Ribbons of two-inch marble, nested on mirror-finished stainless steel provide landings and the "floating" treads are fully cantilevered from a center mast design. On the south side of the residence are the living and dining areas, anchored by a sleek and statuesque Carrara marble fireplace. The marble flanked powder room is set off with pony hair tiles that adorn the walls. Stunning slab marble throughout the residence, was hand selected and imported from Italy by the owner. The second story serves as a loftlike entertaining floor, running 50 feet long by 35 feet wide, complete with butler's pantry. This flexible family and entertaining space offer two thousand square feet of terrace, an outdoor kitchen, pizza oven and bocce court. A true entertainers dream. A state-of-the-art anodized aluminum Poggenpohl cabinet system with custom panels holds court as the centerpiece of the home kitchen. An 11-foot center island for ample entertaining and catering preparations. High end fixtures and stainless appliances, as well as a dumbwaiter that services the top floor. The north side of the mezzanine is devoted to the primary suite and an adjacent office and two private en suite guest suites that are separated by a study/library. An open and airy flow compliment the feel of the layout, easily transformed into private quarters. The primary bath boasts an enormous and elegant marble tub set into an alcove flanking the windows. Four, bookend matched, pieces of marble slab make up the floor. "Acid etched and clear glass walls are carefully choreographed to permit both interior privacy without restricting water views on three sides including Lake Michigan, The Chicago River and North Pier Inlet, " says MacEwen. "As with all the lights in the residence, the lights were custom fabricated by Nulux, a company known for gallery and museum lighting."
