Ida & Billy

Ida Sze and Billy Chan met while working at Herzog & de Meuron before co-founding Ida & Billy in 2013. Striving for simplicity, and paying attention to requirements and character of space, the team has achieved a genuine identity for each project at any scale, from small-scale residential, such as the Bridged House in Hong Kong, and community centres to towers and urban renewal projects. idabilly.com
