When I think about the most glamour interiors of the 70s, I think about this townhouse, on 101 East 63rd Street, which carries glamour history. Started as a 19th-century carriage house, it was transformed by Paul Rudolph for real-estate lawyer Alexander Hirsch and his partner, Lewis Turner in 1967. In 1974, it was purchased by American fashion designer Halston, who for the next 15 years utilized it as his bachelor pad, where he had held many publicized parties. It was then acquired by Gunter Sachs, the Swiss photographer and former husband of Brigitte Bardot who hung black-and-white Warhol photographs of Halston’s crowd and such celebrities as Jacqueline Onassis, Bianca Jagger, and Truman Capote. Sachs who had an amazing taste for art and great modern design, used it until he died two years ago, when it was on the market for $38mm.
