Carlton House

It's been a couple weeks since we've seen a sale break the $50 million mark, but lo and behold, the penthouse at Extell Development's Carlton House has just sold for $52 million. According to city records filed today, the top unit sold at a markdown, originally listed for $65 million back when it first hit the market in October 2013. The price cut, however, shouldn't discount what's inside. The six-bedroom, six-plus-bathroom, 8,988-square-foot Upper East Side duplex features a private outdoor roof space (there's 5,261 square feet of outdoor space in total), en-suite bathrooms in all the bedrooms and wrap-around terraces. The building itself also boasts quite an interesting backstory. It was originally designed in 1940 by Kenneth B. Norton, but not completed until 1950 as construction was halted during World War II. After purchasing the building in 2010, Extell hired Beyer Blinder Belle to convert the structure into condos. The job cost a reported $350 million and Extell's President Gary Barnett told The New York Times that the decision to preserve the building was “actually more expensive than if we tore the damn building down and built it again.”
