Yet another Upper East Side megamansion is in the works

Looks like the Upper East Side could be getting another Frankenhome: New York YIMBY reports that a townhouse conversion, which would smush two existing homes into one huge megamansion, is set to go before the Landmarks Preservation Commission for approval tomorrow.

The houses are located at 53 and 55 East 92nd Street, and the redesign is due to be helmed by Steven Harris Architects, one of the city’s go-tos for luxe townhouse conversions. The firm was also responsible for the conversion of 85-89 Jane Street from two low-rise buildings into one sprawling mansion. That project received LPC approval last October, so they’re familiar with the landmarks song-and-dance.

As for the 92nd Street properties, the plan is to convert them into a six-story, 11,305-square-foot home—so, yes, a megamansion, according to plans on file with the Department of Buildings. Currently, the two structures both stand five stories tall, with five apartments in No. 53 that will be lost as a result of the conversion. According to the DOB filings, the new megamansion would have a basketball court, a gym and sauna, and a rec room; the LPC plans show more of its over-the-top amenities, including a screening room, a “yoga pavilion,” a full-floor master suite (with his-and-hers dressing rooms), and a front terrace with a hot tub.

The proposal on file with the LPC—the two homes sit within the Carnegie Hill Historic District—also sheds more light on how the conversion would change the two townhouses. The facade of the buildings would be restored, with new period-appropriate details (including windows and doors) added. The rear facade, meanwhile, would get major changes, with painted steel and glass windows and bronze screens among the proposed changes.

Of course, there’s a chance these plans could change per the whims of the LPC—that’ll become clear after tomorrow’s meeting.
