Spectacular East Winnetka in-town oasis on almost 1/2 acre of lushly landscaped grounds offers a singular opportunity to walk everywhere from a private, fully renovated classic located in a premier location with 150 ft frontage, just steps to town, train, and beach. Meticulously transformed and completely reimagined inside and out with one of the best first floor living spaces, this 6 bedrooms and 5.1 bath home showcases the highest quality finishes and attention to detail, including a thoughtfully redesigned floor plan for today's lifestyle, exquisite architectural millwork and replaced hardwood floors, every modern amenity, and newer sun-filled windows with serene green views. Complete reworking of the landscape and hardscape by Midwest Arbor resulted in gorgeous panoramic grounds, gardens, grassy play areas, and bluestone patios, creating an incredible outdoor living environment. Spanning the front of the home, a bluestone patio overlooking the professionally manicured yard with magnificent mature trees, welcomes you to a picturesque verdant enclave. The inviting foyer with elegant wainscoting leads into a gracious living room complete with a gas fireplace framed by a handsome mantel adjacent to a bright, airy sunroom with stunning views of the breathtaking grounds. The dining room, accented with built-ins, flows seamlessly into the exceptional, recently reconfigured and renovated, cook's kitchen with a long island with new quartzite countertops, new marble backsplash, and high-end appliances. Adjacent is a sitting area perfect for play or relaxation with access to a private bluestone patio to enjoy al fresco dining and outdoor living. The sunny kitchen opens to the incredible family room with soaring ceilings, skylights, centered by a handsome fireplace, with patio doors opening to a stunning bluestone terrace. A great breakfast room, featuring a fireplace and architectural built-ins, shares a bluestone terrace: ideal for casual dining inside and out. Thoughtful design for everyday functionality is evidenced by a fabulous mudroom off of the heated 2 car attached garage and a full bath (great for beach days or muddy pups) on the main level. Upstairs the primary suite is a retreat in itself, with a private office, warm gas fireplace, and laundry. The recently renovated truly luxurious bathroom (2021) features designer marble and tiles, a jacuzzi tub, heated floors, a heated towel rack, gorgeous custom cabinetry and hardware, as well as a spacious custom walk-in closet. Three large additional bedrooms with a renovated hall bath and an ensuite bath . Two of the bedrooms open to a charming sunroom, providing an ideal space for relaxation, homework, or play. Tree top views abound in the sizable 3rd floor with a great hang out space in the expanded rec room, additional bedrooms, a renovated full bath, and a private back staircase ideal for guests or family members needing their own space. The basement provides even more space whether a rec room with workout room, game room, and a wine cellar. The property boasts 4 garage spaces; a 2-car attached garage and a 2-car detached garage. The exterior was revamped with new stucco (2020), skylights, gutters/soffits, and roof (2019). Truly turnkey, this home offers a rare blend of unparalleled elegance, functionality, and privacy with an in-town location and a phenomenal East Winnetka lifestyle.
