Available for the first time in forty years, this 4,500 sqft full-floor Gold Coast cooperative offers a rare combination of architectural pedigree, volume, and ease. Originally owned by the building's architect, Philip Maher, the residence was later acquired by Potter Palmer II, who presented it as a wedding gift for his son, Potter Palmer III. The apartment was decorated by the current owner with interiors by Colfax and Fowler, enhancing the home's original character with a timeless and livable aesthetic. 10.5-foot ceilings and beautifully preserved original detailing include refined moldings, paneled walls, herringbone floors, and two fireplaces. The library, designed by David Adler, has light-pickled knotty Canadian spruce paneling and includes a concealed door to the living room. Additional Adler-inspired elements include an imported Versailles parquet floor in the primary suite and the primary bath finishes. The public rooms are gracious yet comfortable, including an elegant entry foyer, expansive living and dining rooms, and a newer white Christopher Peacock kitchen complemented by the original butler's pantry and a breakfast room. This residence enjoys open views of Goudy Park, Lake Michigan, and the city skyline. There are three large en suite bedrooms, along with two maids' rooms and an additional full bath, offering flexibility for guests and home office use. The primary suite was reconfigured by Maher to include dual baths and a beautifully paneled dressing room. Additional features include SpacePak central a/c, stacked in-unit laundry, a lobby-level laundry room with a newer side-by-side washer/dryer, and a private storage room. Convenient parking options are nearby, including a self-park garage at 1310 North Ritchie Court, just one block away. This is a rare opportunity to live without compromise, offering the comfort, architectural integrity, and prestige of a grand residence, paired with the ease and security of cooperative living in one of Chicago's most enduring neighborhoods.
