After studying languages in Milan, she founded Strato with Marco Gorini. She designed the Altro Casa collection (plates, glasses, wooden trays, silver saucepans), and collaborated in the opening and launch of the “Spaziostrato” Concept Store in Milan. In 2002 Gianna edited the “Work with taste” book published by Edizioni Corraini. From 2002 to 2004 she was the chairwoman of the Casa Malaparte association in Capri. From 2005 to 2011 she designed several interiors in Morocco, within the Medina of Marrakech, in Costarica, and Los Angeles. She is also responsible for Strato Milan, and collaborates with internationally renowned architects and designers. Her passion for design, art and conviviality makes her the promoter of a living concept based on a space inspired by the rigour of shapes, in which beauty is not identified with luxury or ostentation but is rather a sensual and emotional experience of sophisticated comfort. In 2015 she edited for Strato the "Strato photo history 1990 - 2014" book.
