Set in the iconic mansard roof of the premier building in Lincoln Park is this extraordinary half-floor penthouse. Custom designed and built in 2017 by dSpace Studio and Norcon Construction. This home won the 2018 American Institute of Architects Award for outstanding design. Sprawling across 4,250 sf this home features 12-foot ceilings and exquisite museum-level details including a minimalist reveal in lieu of traditional baseboards, wide plank European white oak millwork and flooring set in a oversized herringbone pattern, dramatic arched windows and doors, framing jaw dropping daytime and nighttime views. Traditional materials, custom raw steel shelving, and an extraordinary lighting design combine to deliver Scandinavian elegance with a French flair, drawn from Lucien Lagrange's Haussmann-esque design of the building. The inward curve of the perimeter walls is dictated by the shape of the exterior roof line. This home feels like a modern Paris loft. The spacious, open floor plan includes three ensuite bedrooms, an office, living room, dining room, family room and kitchen with Sub-Zero, Bertazzoni and Bosch appliances. Special attention was paid to acoustical engineering and the custom mechanical systems. The HVAC is a Daikin Hydronic 10-Zone system that allows any room to be heated or cooled independently. A large bike/storage room also comes with the home, as well as four deeded parking spaces, which are included in the price. If a 4th en-suite bedroom is needed, the plumbing is in place. The seller custom built the residence from raw space. LP2550 is staffed with the best of the best and offers valet parking, in-house dry cleaning, an oversized swimming pool and sauna, steam rooms, a whirlpool, yoga room and sun deck. Other amenities include a state-of-the-art fitness center, movie theater, game room, club room and library. The building also has a private and lushly landscaped 1.25-acre park with a designated lounge area and dog run. If you're looking for extraordinary, this is a must-see home.
