New York’s Upper West Side has long been a coveted area of the city, but few new developments have risen on the horizon in recent decades. However, 470 Columbus and West 83rd Street on Manhattan’s Upper West Side is about to get some new, Passive House-certified apartments that will put sustainability front and center on the block. Designed by award-winning BKSK Architects, Charlotte of the Upper West Side, as the complex is named, will house seven apartments, each with four bedrooms with en suite baths and a separate primary bedroom wing.
