Located on Singapore’s famed Orchard Road, Pan Pacific Orchard (see Figure 1) encapsulates WOHA’s pursuit of nature-positive vertical urbanism by rethinking the tropical urban hotel. It shows the breaking down and humanizing of megastructures into vertically stacked landscapes and social spaces. It makes the case for buildings as active participants of the city, serving the common good and increasing the amount of nature and biodiversity. It demonstrates a high-density, high-amenity built environment that is more liveable, sustainable and desirable. Pan Pacific Orchard Hotel makes a compelling case to pivot towards a “new normal,” where urbanism values coexist with nature.

Top five finalists will present to the jury at the CTBUH 2025 Conference. Winners will be announced at the conference. 

The competition will involve two rounds of jury review. The first-round jury will evaluate all submissions and select five finalists. A separate final-round jury—comprising prominent professionals participating in the CTBUH 2025 Conference—will then determine the five winners and their placements. This final jury will represent an international, multidisciplinary group of tall building experts. The announcement of the final-round jury members will be made closer to the start of the CTBUH 2025 Conference.
