The architecture firm (Athens, 1989) emerged from the many years of collaboration of Theoni Xanthi with Gerasimos Zakynthinos and Thodoris Androulakis. Apart from private projects, a large section of its architectural study and practice has originated from awards in national and international architectural competitions.The perspective of the office combines open large-scale design with the detail of matter, as manifested in architectural materials. In this context, the architectural concept bridges natural, social and cultural environments, and creates spaces for a modern human-centered way of life that promotes synergy and interaction.In 2008, the office was entitled XZA-Architects. XZA-Architects have so far received many and important distinctions, as presented in numerous publications.
