Roberto Righetti received an honorary degree in architecture at the Istituto Universitario di Architettura of Venice (I.U.A.V.) by presenting a dissertation on the placement of the Peggy Guggenheim collection in Venice. In 1987 after a few years of internship he opened his own professional studio in Venice and concentrated on Italian and international architectural contests.
In 1989 Roberto Righetti won the contest for the organization of the interiors of the ex-church Saint Paul of Macerata developed with the cooperation of I. Cappai and P. Mainardis. The work was created in 1996. In 1990 he won the contest Spazio pubblico ed arredo urbano for Pergine Valsugana (Italy) along with G. Azimonti, K. Bunte and M. Morini. Thanks to the recommendation he received in 1992 while attending the award Premio Nazionale di Architettura Luigi Cosenza in Naples, he was invited to participate in the bid for the designing of an office building in San Donato Milanese by the Quartiere Affari: he scored second place.
At the same time, he also worked as a model-maker on behalf of cultural centers, architectural firms, and architecture and design exhibits. His models were displayed at the P.A.C. of Milan for the anthological exhibit by I. Gardella in 1992 and at the Triennale exhibit center of Milan regarding G. Muzio (1994) and M. Zanuso (1999) and at the Permanent Museum of Milan in occasion of the exhibit Cantico 2000. He also placed 3rd, 4th and 5th International Architecture Exhibit at the Biennale exhibit center of Venice, at the exhibit Brasil 1920-1950 at the I.V.A.M. of Valencia in Spain and at the Museum of Moderm Art of San Paolo in Brasil, at the Fondazione Giorgio Cini and at the Museo Correr of Venice.
Since 1999, after participating in the Laboratorio per il Design (Design Laboratory) workshop at the Palazzo Fortuny in Venice on the theme Conoscenza della luce (Getting to know the light) destined to the designing of luminaries, he has been dedicating his talents to the designing of lamps and objects with innovative materials.
