Description

Built circa 1900 by architect Theodore E. Thomson, this gorgeous Renaissance Revival style townhouse was gut renovated ten years ago, and restored to its original single family splendor. Six stories plus cellar, the spacious 9000+ sq ft, are elegantly designed and constructed with the finest materials and finishes. With five bedrooms, seven full baths, four half baths, an elevator, a penthouse gym, five outdoor terraces, a landscaped garden, and an 1,800 sq. ft. recreation space in the cellar, this home is a dream for both living and entertaining. Finished by the current owners in 2008, the original home was taken down to the four outside walls and reconstructed of steel and concrete. Installed are multi-zoned Mitsubishi heating and cooling systems, radiant floor heating throughout, Crestron security, Lutron lighting, mahogany stairs and hard wood floors. This state-of-the-art renovation includes thumb-print security system and video surveillance accessible by touch-screens throughout the home. Reproduced period details, such as unusual wide stair banisters with matching newel posts, and muted raised-panel wainscoting, reflect an earlier time in construction and lend a venerable feel to this new-construction home.
