Modern Architectural Townhouse with Private Carriage HouseBrilliantly marrying historic townhouse classicism and the best of modern design today, 251 East 61st Street is a completely reimagined townhouse and carriage house ensemble, a true private compound masterfully conceived by TRA Studio as a cohesive, design-forward single-family residence with guest house. The restoration undertaken by the current owner included expanding the townhome with an additional floor, which houses the Master Suite with amazing skyline views. The vertical living was enhanced by the installation of an elevator.This approximately twenty-foot-wide, six-thousand-square-foot residence is crowned by a new landscaped roof deck with open city views and anchored by a tranquil courtyard. As part of a comprehensive renovation, a skylit cellar gallery now connects the two structures, while an interior elevator ensures seamless access across all levels. Exceptional horizontal and vertical flow—including a dramatic double-height living room with a sculptural fireplace—creates a rare sense of privacy and flexibility. The restored façade is clad in stucco, scored to recall limestone in harmony with the surrounding Treadwell Farm Historic District. Oversized casement windows and multiple skylights bring sunlight and softness to this thoughtfully modernized home.Entertaining spaces include a Poliform-appointed chef's kitchen, a luminous formal dining room, and a limestone courtyard outfitted with a gas grill, sink, refrigerator, speakers, and lighting—perfect for elegant evenings outdoors.Upstairs, the full-floor primary suite features skylights, custom closets, and a spa-like bathroom with dual vanities, soaking tub, and walk-in shower. Each of the additional bedrooms is appointed with its own en-suite bathroom, ensuring comfort and privacy throughout.The separate carriage house, currently configured as a self-contained guest residence, offers exceptional flexibility—ideal for extended family or a private workspace. It includes its own Poliform kitchen and double-height great room with wood-burning fireplace.
