Description

Showings on Mondays - 9:00-12:00, Thurs - 9:00-2:00, and Fri- 12:00-5:00 only. Welcome to Residence 12C at 1148 Fifth Avenue, a distinguished home in one of J.E.R. Carpenter’s most celebrated Fifth Avenue cooperatives. This grand, light-filled nine-room residence exemplifies Carpenter’s hallmark elegance, with soaring 10-foot ceilings, balanced proportions, and a beautifully articulated prewar layout. Centered around a gracious 20’ x 8’ entrance gallery, the residence offers a refined, symmetrical flow characteristic of Carpenter’s finest designs. A semi-private landing opens into a formal gallery leading to the expansive living room, anchored by an original wood-burning fireplace and a side view overlooking the treetops of Central Park. To the south, French doors reveal a sun-drenched dining room, its light and scale ideal for grand entertaining. Original oak floors, brass hardware, and preserved millwork throughout the principal rooms speak to the home’s meticulous stewardship and timeless craftsmanship. The renovated kitchen merges classic architecture with modern convenience, opening onto the former butler’s pantry to create a spacious eat-in area with thoughtful storage and a vented washer/dryer. Two adjoining staff rooms retain their original details and functionality, now ideal as home offices or guest quarters. A custom-designed wine pantry offers additional sophistication and utility. A private hallway leads to three large bedrooms and two well-appointed baths. The primary suite, facing north with partial park views, features three walk-in closets and an en-suite bath that also adjoins the library. The two secondary bedrooms share a spacious, windowed bathroom. The cooperative’s history of board-approved alterations allows for the possibility of a powder room and a fourth full bath within this line. This residence includes a private storage unit, bicycle room, and access to the newly renovated fitness center. The building—pet-friendly and offering up to 50% financing—encourages central air installation. A 2% flip tax is applicable. Located in the heart of Carnegie Hill along Fifth Avenue’s most distinguished residential stretch, 1148 Fifth Avenue offers an exceptional lifestyle defined by impeccable service and timeless elegance. Residents enjoy white-glove amenities, including a 24-hour doorman, live-in resident manager, and a dedicated, attentive staff. Overlooking Central Park and the 95th Street playground, the building is surrounded by the neighborhood’s most esteemed cultural and educational institutions, including many of New York’s finest private schools. Nearby Madison Avenue boutiques and restaurants further enhance the appeal, while Mount Sinai Hospital is just moments away—making this one of Fifth Avenue’s most sought-after and refined addresses.
