Under Boudin's leadership, Maison Jansen provided services to the royal families of Belgium, Iran, and Serbia; Elsie de Wolfe, and Lady Olive Baillie's Leeds Castle in Kent, England. The firm's most published work was a project by Boudin and Paul Manno, the head of Jansen's New York office, for the U.S. White House during the administration of John F. Kennedy. At the same time, Jansen completed the interior of the motor yacht "Chambel IV", now renamed "Northwind II". "Northwind II" is one of the few remaining complete Jansen commissions.
