The Space for Architectural Collaboration Is Increasingly Valued Amid Climate Change and Urbanisation

The Indonesian architecture industry is seen as needing more spaces for collaboration that can generate adaptive design ideas in response to the challenges of climate change, urbanisation, and the cultural diversity of Nusantara. Architecture competitions are no longer merely about showcasing work, but are increasingly directed as spaces for dialogue to deliver more sustainable living environments. In this context, the company providing water solutions and sustainable housing has again organised the LIXIL Architectural Design Competition 2026, or LADC 2026. The event is expected to serve as a platform for architects and architecture students to explore designs relevant to future challenges. Marketing Director of LIXIL Water Technology Indonesia, Arfindi Batubara, said Indonesia has thousands of identities with varying challenges across regions, from urbanisation pressures to climate change. Therefore, according to him, architecture must not only deliver aesthetically pleasing designs but also be capable of offering solutions. “LADC does not seek designs that are merely beautiful, but ideas that can become conversations and solutions,” Arfindi said in a statement on Wednesday, 21 May 2026. This year, LADC takes up the theme “ARCHIPELAGO DIALOGUES: Architecture as a Space of Co-Creation.” The theme highlights Indonesia as an archipelagic nation with cultural and natural diversity, and development challenges that differ yet remain interconnected. The competition features an international panel of judges, including Andra Matin, Gregorius Supie, and Richard Wood. In addition, the winners will have the opportunity for a studio exchange and to undertake an architectural journey to Japan. According to Arfindi, LADC is not only focused on the final results but also serves as a platform to broaden dialogue and exploration of ideas within Indonesia’s architectural scene. He hopes the competition will spur more inclusive and sustainable design approaches. Registration and submission open from 18 May to 5 July 2026, with two main categories: professional and student categories. The culmination of the competition and the announcement of the winners will be held as part of the LIXIL Day of Architecture & Design 2026 on 12 August 2026.
