The Palais du Mobilier Bonn Frères (in English: Bonn Frères Furniture Showroom) is an Art Deco-style building in Luxembourg City, Luxembourg, designed by the architect Léon Bouvart (1883–1933) and built in 1925–26 by the contractor Achille Giorgetti for the Bonn family.
[1] Stanislas Bonn (1833—1888) was a furniture merchant who quickly adapted to the industrialized methods of production during the mid-19th century, and opened a furniture store in Luxembourg in 1855.
The furniture business expanded to eventually occupy the entire building and was eventually named "Bonn Frères" (Brothers), which was retained as the official name until 1994.
The building has seven storeys and is the largest furniture store in Luxembourg.
In the latter renovation the original structure was integrated with the houses neighboring it to both the left and right; a section called Carré Bonn housing offices was created on the upper floors, while the lower 3 levels are reserved for the furniture and decor business showroom.
