When he won the Pritzker Prize on March 24, the Japanese architect Shigeru Ban had a very busy day. As the 37th winner of architecture’s biggest prize — the profession’s Nobel — Mr. Ban made all the major papers, had appearances on CNN and NPR, and even sat down with Charlie Rose.

The day after Mr. Ban won the Pritzker, the Douglas Elliman broker Holly Parker had a very busy day, too. “The phone started ringing, and it just hasn’t stopped,” said Ms. Parker, who, thanks to Mr. Ban, has won a prize of her own.

Since October 2012, she has been trying to sell a three-bedroom condominium inside the Metal Shutter Houses in West Chelsea, Mr. Ban’s only completed project in New York. The $7 million duplex already had Mr. Ban, one of the world’s best known architects, behind it, even before he won the Pritzker. The honor is not only for his distinctive homes across Japan and a branch of the Pompidou in Metz, France, but also for disaster housing utilizing unusual materials like cardboard tubes and shipping containers.

Just as when an author wins a Pulitzer and suddenly a stack of books appears at the front of Barnes & Noble, bearing golden stickers, Ms. Parker’s listing was now on many buyers’ minds.
