10 East 53rd Street

With stunning views of Central Park just to the north, SL Green's Harper Collins Building at 10 East 53rd Street combines timeless architectural style with a 2009 Energy Star award for its operational efficiency, which will only increase thanks to a pending capital improvement program.

Part of Emery Roth & Sons’ extensive Midtown design portfolio from the mid-twentieth century – when the firm was perhaps New York City’s most important and influential architect – the 38-story, 390,000-square-foot 10 East 53rd Street (also known as the HarperCollins Building) dates from 1972 and is headquarters of the eponymous publishing house, which anchors the building by leasing more than 60 percent of its total space.

The boutique tower – once dubbed a “jewel box of an office building” – is located in the Plaza District, just off Fifth Avenue between East 52nd and 53rd Streets and its upper floors have long been a favorite of financial services tenants thanks to their sweeping Midtown and Central Park views, oversized windows on three exposures, and minimal interior columns.

But today, after a 2012 acquisition from Hines, 10 East 53rd Street is owned by SL Green: New York City’s largest commercial office landlord and a dedicated proponent of sustainability within commercial real estate. Individual office floors feature tenant-controlled supplemental air conditioning, extensive natural daylighting, renovated common corridors and elevator cabs, and sweeping views of Midtown and Central Park to the north.

In 2009, 10 East 53rd Street’s operational efficiency earned it an Energy Star award with a score of 75. Since the acquisition, SL Green has announced major renovation plans – upgrading the lobby, plaza, elevator cabs, and building systems that will ensure 10 East 53rd Street’s operational efficiency for the rest of the 21st century.

In addition to HarperCollins – whose lease doesn’t expire until 2014 – other notable tenants at 10 East 53rd Street include Metropolitan Bank & Trust, Optima Fund Management, and Relais & Chateaux.
