Welcome to 20 E Cedar Street, Unit 4D - a landmark Gold Coast address where the soul of a century-old building meets the comfort of a home that has been updated with genuine care and intention. Perched within a distinguished 1929 building, this 2 bedroom, 2.1 bath duplex spans 2,560 square feet across two gracious floors, delivering a sense of space, privacy, and architectural character that is increasingly rare in the Gold Coast at any price point. On the main level, Cathedral ceilings frame the living room, anchored by a gas fireplace and enhanced by a newly updated ceiling finished in 2026. South-facing courtyard and ivy wall views create a sense of greenery and calm that is truly surprising in the city's core. Solid oak hardwood floors run throughout, and the living room transitions seamlessly into a formal dining space graced by two custom statement pendant lights. The kitchen has been equipped without compromise. Sub-Zero refrigerator and wine fridge, Wolf range, and Miele oven, microwave, and dishwasher form the appliance suite. Radiant NuHeat heated floors warm the kitchen floor underfoot, and a custom built-in nook provides the kind of casual, lived-in corner that makes a kitchen feel like a true gathering place. A spacious family room/den rounds out the main level - ideal as a home office, media room, or private guest overflow - alongside an in-unit LG washer and dryer. Upstairs, the two bedrooms are each generously scaled and finished to the same exacting standard. The primary suite features custom built-in wardrobe storage and an ensuite bath finished in elegant stone, with radiant heated floors that are a quiet luxury unto themselves on Chicago mornings. The second bedroom is equally proportioned and served by a refined full bath with heated floors as well. An additional powder room on the main level ensures guests are accommodated graciously. Beyond the interiors, the unit has been invested in throughout: brand-new central air conditioning (2024), whole-home audio system, Ecobee thermostats, and NuHeat heated floor controls all reflect the thoughtful stewardship of a home that has been lived in and loved. 20 E Cedar is itself a destination. Originally constructed in 1929, it is 100% owner-occupied and carries $492,942 in reserves with no current or anticipated special assessments. Amenities include 24-hour door staff, a stunning 19th-floor common roof deck with city and lake views, a first-floor fitness room, and a tucked-away outdoor patio. The all-inclusive monthly assessment of $2,277 covers heat, water, gas, cable, internet, doorman service, exterior maintenance, lawn care, scavenger, and snow removal. Leased parking is available directly across the street at 33 E Cedar Street for approximately $300/month. Two pets per unit, 70 lb. maximum. Quiet, tree-lined Cedar Street places you moments from Oak Street Beach and the lakefront, steps from Lincoln Park, surrounded by the world-class dining, boutique shopping, and cultural richness that define Chicago's Gold Coast. For the buyer seeking extraordinary square footage, a building with a genuine century of history, and a home that has been elevated with care at every level, Unit 4D is a singular opportunity.
