Selcuk Avci and Sanja Jurca Avci established Avci Architects in London in 1989. In its first year, the practice won the top prize in the European Union biannual Energy Efficient Buildings Competition, a culmination of years of experience in sustainability which set the tone for the direction of the practice. Although the practice specializes in many sectors in terms of programme, sustainability has become an underlying driving ethos, from the scale of regional masterplanning down to the design of a single product.
