635 Madison Avenue is a 19-story, 176,530 square foot office and retail tower located between 59th and 60th streets and across the street from the GM building. It was completed in 1958. L&L Holding, headed by David Levinson and Robert Lapidus, acquired the ground under the Emery Roth & Sons-designed building in 2007 for $110 million. In 2011, Ashkenazy Acquisition, a New York City-based firm that invests in retail and office real estate, bought what was left of the ground lease, 44 years, from West Land. The ground lease expires in 2030 and includes one 21-year renewal extension option. The transaction took three years to close, eventually at $61 million, down from $70 million originally agreed. Ashkenazy assumed some securitized debt. In April 2014, SL Green Realty, the real estate investment trust (REIT), acquired the fee interest at the property for between $135 million and $145 million. Current retail tenants include British cosmetics firm Molton Brown and French crystal glassware manufacturer Baccarat. MK
