Sumu was recognized for a concept of regenerative ideas. Although sustainable architecture that preserves the environment has existed in the past, it is realized in this project with the architectural idea of enriching the environment.

The jury of iF released the following statement regarding its decision to issue the Gold award:

"Taking extraordinary care not to disturb the fine balance of human and natural presence at this World Heritage site, this building abounds with subtle representations of Japanese master-craftsmanship. Like a haiku, this form reveals its depth on closer inspection."

Additionally, Sumu received the "Jury award", the highest award in the "Susutainable Private House" category of the A+Awards 2023, a category introduced for the first time this year. Winners of other architectural genres in the same category include Foster and Partners and UN studio. In addition, Sumu has won 5 other awards. (Please refer to Technical Information)
