Description
Extraordinary Scale, Light & Architectural Presence Built in 1887 by architect John C. Prague and renovated by one of New York’s most respected builders, this five-story home seamlessly combines a sophisticated four-bedroom residence with an impressive six-room office for an exceptional live/work environment. Enormous casement windows, exceptional millwork and thoughtful design bring a distinctly European sensibility to a setting that balances traditional architecture with modern living. The house can easily become a compelling, grand single-family residence–all within a 20' wide lot. The house has a private elevator. The residence, on the upper floors, features four bedrooms, exceptional millwork, thoughtful design, voluminous entertaining spaces, a showstopping south-facing kitchen. The office, on the lower floors, offers exceptional light, has direct garden access and provides generous space for 25 people. It operates entirely independently from the residence, with its own reception room for business meetings. Exciting architectural highlights include outdoor space on each floor, working fireplaces, a newly designed staircase with skylight atop, central air conditioning, and a large gym. *A third party, FloorPlanSource, states the interior gross square footage to be approximately 7,900SF.
