Marco Casamonti graduated from the University of Florence in 1990 and was appointed Professor of Architectural and Urban Planning in the faculty of Architecture at the University of Genoa in 2001.
He carries out in-depth research and critical reflection on various architectural topics, has published numerous articles and essays and actively participated in conferences and lectures. He has been editor-in-chief of the international magazine Architettura Area since 1997 and has been co-editor-in-chief, along with Paolo Portoghesi, of Materia magazine since 1999, both published by Gruppo 24 ORE. In 1988, he founded Studio Archea with Laura Andreini and Giovanni Polazzi, and in 1999 Silvia Fabi joined the firm.

Archea is a network of around 100 architects, who work in seven different offices located in Florence, Milan, Rome, Beijing, Dubai and São Paolo. The interests and research activities of the firm encompass landscape and city, buildings and design and while the focus is very much on architecture, their projects also include graphic design, publishing, exhibitions and events. The complementary nature of these various fields and the different scales of the projects, from criticism to construction site, make it possible for the firm to operate in a wholly integrated manner in all the various phases of a project. Each of the firm's partners combines their professional activities with teaching or research within the Faculty of Architecture at the University of Florence or Genoa. Some of the most important completed projects include: the Nembro Public Library (Bergamo, Italy), the new Antinori Winery in San Casciano Val Di Pesa (Florence), the UBPA B3-2 Pavilion World Expo 2010 and GEL, Green Energy Laboratory in Shanghai, renovation and expansion of the Perfetti Van Melle industrial complex in Lainate, Milan.

Currently under construction are the Tirana Tower, Albania, the "Meravigliosa Island" at the "World Islands", Dubai, the Changri-La Winery in Penglai and the Li Ling World Ceramic Art City, in China.
