This historic Upper East Side townhouse has classic exteriors, but fully modernized interiors

With so many high-end buyers interested in owning a classic New York City townhome without sacrificing on luxury amenities, more and more owners are renovating their historic properties to maintain their stately facades but completely modernizing the interiors, as Mansion Global recently reported. This five-story $14.790 million, circa-1875 townhouse on the Upper East Side is a prime example, with a classic facade that's been renovated in line with historic preservation specifications; inside, however, it's completely 2017, with an elevator, HVAC climate control, a Sonos music system, and built-in security.

Located in the Treadwell Farms Historic District (a small landmarked enclave on East 61st and East 62nd streets), the property has just undergone an extensive renovation, and includes ample entertaining space, including a sizeable living room, formal dining room, and eat-in kitchen with floor-to-ceiling windows that lead out into the 35-foot landscaped backyard garden:

The backyard is just one of five outdoor spaces on the property, including a terrace off the master bedroom, another located off the fifth-floor library, and a finished roof space (not pictured). All told there are five bedroom suites and six full bathrooms finished in stone slabs:

There's also a finished basement, plus interesting details throughout, including solid rustic white oak floors, crown moldings, and a dumbwaiter, the better to ferry food and drinks from the kitchen to the entertaining spaces on the upper floors. Since it's set up as a single-family (and doesn't have a separate unit you can rent out as an investment), the home is tailor-made for a well-off owner looking to live in old-school luxury.
