This extraordinary Humboldt Boulevard mansion is perfectly positioned along one of Chicago's most picturesque boulevards in the coveted Logan/Palmer Square neighborhood, overlooking the park and set on a nearly double city lot extending an impressive 155 feet deep. This remarkable, recently designer-owned 6-bedroom, 5-bath residence has been completely reimagined with an impeccable blend of timeless architectural character, elevated craftsmanship, and modern luxury. Beyond the inviting front porch, beautifully curated interiors unfold with hardwood floors, original pocket doors, custom millwork, a gas fireplace, and exquisite grasscloth and designer wallcoverings from House of Hackney and William Morris. The main level offers an exceptionally flexible, open layout designed to adapt effortlessly to the way you live and entertain. A gracious formal living room features original French doors and a beautiful picture window framing picturesque views of the park, while the adjoining formal dining room, anchored by a fireplace, offers the versatility to serve as an elegant dining space or sophisticated lounge. At the heart of the home, the stunning custom white gourmet kitchen features high-end professional appliances, a dramatic Calacatta Gold marble island, and a picture window overlooking a blooming chestnut tree. The generous open eating area adjoining the kitchen provides even more flexibility, easily functioning as an everyday dining space or comfortable family room, allowing multiple configurations for both formal and casual living. From here, the home flows effortlessly to an oversized deck, herringbone paver patio, and lushly landscaped private backyard oasis. A showpiece full bath with a white enamel cast-iron clawfoot tub and Restoration Hardware vanity completes the main level. Upstairs, the serene primary suite offers a beautifully appointed Carrara marble bath with an oversized glass shower, heated floors, and Restoration Hardware vanity, along with a spectacular custom dressing room that was previously one of the bedrooms. An additional two generously sized bedrooms, an updated hall bath, and a large balcony area with tranquil treetop views complete the second floor. The fully transformed third level is equally impressive, offering soaring cathedral ceilings, wide-plank quarter-sawn oak floors, built-in window seats, designer Rejuvenation lighting, and an expansive family/theater room ideal for relaxing, entertaining, or working from home. A rear staircase connects every level, including the completely renovated walk-out English basement, where heated tile floors, abundant natural light, a gracious home office with a built-in daybed-or additional bedroom with an adjacent full bath-and a spacious king-sized guest suite with its own beautifully appointed bath create exceptional flexibility. Even the laundry room has been elevated, with two sets of washers and dryers, a full-size steamer/dry-cleaning cabinet, soapstone countertops, a sink with a smart faucet, and sophisticated custom hardware. Extensive improvements include newer air conditioning, all-newer windows, a 75-gallon water heater, a new city water supply, sump pump, spray-foam insulation, a newer forced-air system on the third floor, a Guaranteed Lead Free Home designation, and so much more. A two-car detached garage and pea-gravel firepit area that doubles as additional parking complete this remarkable residence. The exceptional Palmer Square location places you moments from an incredible collection of casual and fine dining, luxury athletic clubs, grocery stores, and neighborhood farmers markets, while the 606 Trail is just half a mile away. Convenient access to the Blue Line and nearby expressways makes getting downtown, to O'Hare, and throughout the city effortless. A rare opportunity to enjoy the space, flexibility, and privacy of an extraordinary boulevard home while remaining connected to some of the best dining, recreation, and amenities Chicago offers
