MAISON JANSEN Maison Jansen (House of Jansen) was a Paris-based interior decoration office founded in 1880 by Dutch-born Jean-Henri Jansen. Jansen is considered the first truly global design firm, serving clients in Europe, Latin America, North America and the Middle East. This House is located at 23, rue de l'Annonciation, Paris. From its beginnings Maison Jansen combined traditional furnishings with influences of new trends including Anglo-Japanese style, the Arts and Crafts movement, and Turkish style. Throughout the firm's history, it employed a traditional style drawing upon European design, but influence of contemporary trends including the Vienna Secession, Modernism, and Art Deco has also appeared in Jansen interiors and in much of the custom furniture the firm produced between 1920 and 1950. 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.
