The History

Pictured below, left to right, the D’Ascanio family’s first home on Grassy Key was a plywood shed; Rino and Margret D’Ascanio mixing cement in the yard, and the boys off to school in front of the shop.

Started by their parents, Palmerino and Margaret, as Ornamental Cement Products, the company shifted from tile to construction in 1980. Tony branched out to D’Ascanio Development while Franco started Sound Source, the custom audio/video division and Amedeo expanded Ornamental Tile’s services to include cabinetry, lighting, wall coverings and other finishes. In 1991 D’Ascanio Development, Sound Source and Ornamental Tile merged their companies under one roof to create D’Asign Source, moving to its current 25,0000 square foot location in 1999. Primarily focused in the Florida Keys. Work now takes them out of the area as the reputation for D’Asign Source and their specialty building style is the perfect complement to any coastal location.
