The international forum by renowned architectural practitioners, known as ASA Forum, is a much-awaited activity that has been featured in Thailand's Architect's Expo for over twenty years. The forum aims to provide a learning platform for ASA members, architecture students and public audience to update and exchange architectural perspectives with invited speakers whose distinguished works and design ideas are widely recognized. This year the Association of Siamese Architects under Royal Patronage (ASA) is honored to present three groups of architects who practice as a duo: SANAA (Kazuyo Sejima & Ryue Nishizawa) from Japan, Lacaton & Vassal Architectes (Anne Lacaton & Jean-Philippe Vassal) from France, and Langarita-Navarro Arquitectos (María Langarita and Víctor Navarro) from Spain. The interesting diversity of backgrounds, project types, ideas and contexts on which each duo has been working contributes to the variety within the world of architecture that somehow also reflects the inevitable dynamics of the World we share.
