A chapter in this book by the architects Della Valle Bernheimer describes their renovation of 23 Beekman Place, New York, NY, the long time home of Paul Rudolph.
On New York City, 1959 “We need sequences of space which arouse one’s curiosity, give a sense of anticipation, which beckon and impel us to rush forward and find that releasing space which dominates, which climaxes and acts as a magnet and gives direction. This is well illustrated by the Fifth Avenue entrance to Rockefeller Plaza, where one strides forward in anticipation of seeing the sunken court and its activities. Most important of all we need those outer spaces which encourage social contact, again well illustrated by Rockefeller Plaza, the best outdoor living room in America.”
