The Admaston is a 12-story prewar condominium in Manhattan’s Upper West Side, originally built in 1910 by architects George and Edward Blum and converted to condominium ownership in the mid-1980s. The building reads as an intimate, boutique residence of roughly 72 units, presented in an Edwardian/Beaux-Arts idiom with a richly detailed marble lobby, stained glass and period chandeliers that emphasize early twentieth-century craftsmanship. Apartment footprints are classically scaled: multi-room layouts (Classic 6/7 configurations and four-bedroom plans) with lofty ceiling heights often exceeding ten feet, oversized windows, hardwood floors, decorative fireplaces and original moldings and beamed ceilings. Typical interior items include formal foyers, separate dining rooms, large living rooms, eat-in kitchens or breakfast bars, built-in storage and generous closet capacity; many residences still show prewar finishes alongside modernized kitchens and baths. Common building amenities are full-time doorman service, a live-in superintendent, planted roof deck with city views, central laundry, bicycle storage and private storage/cage bins; select units permit in-unit washer/dryers and central air. The property is pet-friendly with a history of assessments for capital work and maintains on-site building services, video security and occasional shared storage offerings. Located on a leafy block between Broadway and the Mall near 89th Street, the Admaston sits equidistant to Central and Riverside Parks and within easy reach of multiple subway lines, restaurants, museums and neighborhood shops, offering a blend of preserved prewar character and full-service condominium conveniences.
