150 East 38th Street

In 1934, Mr. Pettengill, an engineer and antiques dealer hired architect Robertson Ward to combine 150 and 152 East 38th Street into an office and home. House & Garden praised the design in 1936, called the "Pettengill Project," which placed offices and a conference room in the front house and living quarters in the set-back house at 152. Robertson Ward later designed resort buildings in Acapulco and Barbados, and the Mill Reef Club in Antigua. Eventually, the two properties were severed, although the LPC designated 152 East 38th Street in 1967.
