Manhattan House was a ground-breaking new building when it was built in 1950, and for the past year or so (and not without some bumps) has been undergoing a complete stem-to-stern rehab and conversion from rental to snappy condominium. The building’s original design has held up very well over the years, and it is interesting vintage modern space, indoors and out. Designed by the venerable firm Skidmore, Owings & Merrill, the project’s principal architect was Gordon Bunshaft (he later bequeathed his own travertine-clad modernist house on Georgica Pond to the Museum of Modern Art). Period photographs of the Manhattan House lobby show it stylishly furnished with iconic Mies van der Rohe Barcelona Chairs and Pavilion Tables, all part of today’s vernacular in new developments. Manhattan House enjoys full credit for starting the craze for white brick apartment buildings in Manhattan, (910 Fifth Avenue, built in 1920, even “updated” their limestone façade to white brick in the 1960’s.) The “white brick post war” species, so often distained, may soon enjoy a renaissance in popularity. With Manhattan House leading the way, can Imperial House, with its impeccably-maintained Raymond Loewy lobby, be far behind ?
