Costantini has been a trusted source for custom furniture, objects and lighting for a global client base since 2002. 

Its founder and owner, William C Stuart, is a designer and artist who began his career as a multimedia artist and sculptor, practices which continue to inform the work. 

With a studio showroom in New York and a team of artisans at their own workshop in Buenos Aires, the Costantini team is able to connect artisans and artists with acclaimed clientele around the world.  Its artisans work across many disparate materials such as bronze, solid wood, fiberglass, steel, plaster, goatskin, leather, rush, iron, marble, sheepskin and more. 

In 2019 Costantini began representing other artists including the award winning Mirei Monticelli.
