Between 1980 and 1996, designer Lorenzo Negrello worked in partnership with architect Paolo Scagnellato, with two projects being nominated for the "Compasso d'Oro" Industrial Design award. In 1996, he founded S.I. Design, a company specializing in furniture design, particularly for offices and communal spaces, working with leading companies both in Italy and abroad.
Today, S.I. Design is an organization with eight people and is based in Padua. The main focus is on design and technical assistance in product development, which is carried out using solid modelling programs.
