TOSTEM Asia Design Award (TADA) 2025 celebrated its main event in Tokyo, Japan on 27 October 2025. The winners of all categories—Best of the Best Award, Building of the Year Awards, Sustainable Living Awards, and NEXTGEN Award—were announced during the event. With 455 submissions received from India, Indonesia, the Philippines, Thailand, Taiwan, and Vietnam, TADA 2025 marks TOSTEM's growing presence in the Asian market. 

The Best of the Best category was awarded to Bandung based architect from Indonesia, RUANGRONA, with the project FI House. Located in Jakarta, the house blurs indoor and outdoor area seamlessly, with its common spaces plotted around the courtyard inside the house as the main feature. Using GRANTS and ATIS, the interconnectivity between spaces and the house's energy efficiency become the main highlight of FI House. 

Pranala Associates from Bandung, Indonesia receive the Building of the Year Award for their project, JS House. Situated in Bandung, the concrete-clad house features multiple wide openings integrated with GRANTS, ATIS, and EZ products to optimize panoramic view of its surrounding. The house also responds thoughtfully to the tropical climate with broad overhangs that ensure comfortable indoor activities throughout the day. 

Along with Pranala Associates, the Building of the Year Awards were also granted to HO Studio from Vietnam for Tram House, One and a Half Architects Co., Ltd. from Thailand for Veil House, and Studio Sifah Co., Ltd. from Thailand for Laab is More.
