In Chicago, sometimes luxury is a matter of the right address. Designed by award-winning architect Lucien Lagrange, 840 North Lake Shore Drive in Streeterville is that building-the one that's instantly recognizable against our skyline for its grace of form and talked about by Chicagoans for its perfect location, unobstructed views and white-glove service. And now, unit 303, a masterfully renovated 3,900-square-foot 4 bed/4.5 bath single-family condo is on the market-and poised to move fast. Beginning in the foyer, it's evident that careful consideration was paid to custom finishes throughout, including beautiful crown molding and hardwood floors. Moving deeper into the unit, it's apparent that procession and flow were top priorities, too. Wrapping around the kitchen in an L shape, this unit's living and entertaining spaces include an open-concept great room with stylishly defined spaces for both a formal living room and dining room, a more casual family room with floor-to-ceiling built-ins for smart storage, and a handsome WFH study. (Note: The whole home is wired for Sonos via discreet ceiling speakers.) There's also a sizable outdoor terrace that overlooks Lake Shore Park, the Museum of Contemporary Art and Lake Michigan. But it's this unit's elegantly appointed chef's kitchen that's truly the heart of the home. Here, clean white cabinetry, a full-slab marble backsplash, a marble-topped island, a walk-in pantry, and a Wolf/Sub-Zero/Miele appliances suite make mealtime prep a dream. On the opposite side of the floor plan, all three secondary bedrooms feature beautiful en suite baths, and, thanks to a custom Murphy bed that can be tucked away out of sight, the third and largest of the bonus bedrooms doubles as a media room/den. The primary bedroom, however, commands the entire east wing, and features a large walk-in closet and a spa-like en suite with a dual Robern interior-lit vanity, floor-to-ceiling marble tile, a glass-enclosed shower and a standalone Michael Smith soaking tub. A designer laundry room with full-size washer/dryer and a family-friendly mudroom complete the in-unit footprint, while first-class building amenities include additional private storage, two easy-access parking spaces (self-park or valet), wine storage, a fitness center, a 24-hour doorman and on-site management. With turnkey sophistication and room to spread out or come together, 840 N. Lakeshore Drive, unit 303, is modern refinement with an all-access pass to downtown Chicago.
