Elevating transitional design to an art form, 209 E. Lake Shore Dr., unit 3W, is a 5,700-square-foot, 3+ bed/4.5 bath lake-facing, luxury residence located inside East LSD's most prestigious co-op building. Originally designed by Benjamin Marshall, the very same architect who designed The Drake hotel, each floor of the building holds two mirror-image apartments that are laid out so that the library, living and dining rooms all overlook the lake via 63 feet of frontage. Occupying the west half of the third floor, unit 3W retains the best elements of the building's original character - timeless crown moldings, wood paneling, hardwood floors, and a floor plan that supports sophisticated entertaining - but has been completely renovated by the award-winning architects at Wheeler Kearns for modern elegance and impact. Moment one, a fashionable foyer flaunts the highest level of finishes, and links to a gallery-style reception hall. The light-filled living room is grand in its proportions and features sculptural lighting, and connects to a large formal dining room with refined wainscotting that can easily accommodate a large buffet and seated dinner parties for 12+ guests. The library, which is currently styled as a handsome home office, features beautiful built-in bookshelves and a marble-fronted fireplace. The chef's kitchen is absolutely spectacular and features bespoke cabinetry by O'Brien Harris, marble countertops with a high-hone finish that extend into a seamless backsplash, professional-grade appliances including a Wolf range with dual ovens, a massive island with dine-up seating, a butler's pantry, and an adjacent breakfast room with built-in seating, a custom service bar, and more beautiful contrast cabinetry that wraps around an integrated flatscreen. Separated by a bedroom foyer and a long gallery hall with bonus linen and clothing closets, this effortless home has two sizable secondary bedrooms (both ensuite) and a spacious primary suite that includes a chic owners den with its own bath. The primary bedroom is flooded with natural light thanks to a corner position that affords two walls of windows, and features a sitting area, floor-to-ceiling open bookcases, and a luxe ensuite bath with wall-to-wall natural stone tile, a large dual vanity with more custom millwork by O'Brien Harris, a standalone soaking tub, and an oversize steam shower with bench. But there's more... The primary suite also comes complete with an enormous, custom closet with an accessories stations and multiple custom-lit mirrors. Additional callout details include designer lighting throughout, custom motorized draperies, solid stock oak hardwood floors, Sun Valley Bronze hardware, surplus custom storage and a polished laundry room with two washers and two dryers. Building amenities include 24-hour doorman service, engineering and security staff, exercise room and a private yard and patio behind the building. (This pet-friendly building allows both cats and dogs. Valet parking is included in the attached garage, as well as two separate storage rooms within the building.)
