CTBUH 2025 International Student Tall Building Design Competition

The Council on Tall Buildings and Urban Habitat (CTBUH) is now accepting submissions for its 13th International Student Tall Building Design Competition—culminating with an award of $20,000 to be recognized at the CTBUH 2025 International Conference, held in Toronto, from 6–9 October 2025.

The goal of the competition, which is open to all students who are currently enrolled at the university level, is to shed new light on the meaning and value of tall buildings in modern society. This year's competition focuses on “From the Ground Up: Tall Buildings and City-Making,” the theme of the CTBUH 2025 International Conference, to explore the multifaceted approach required to grow and transform cities, emphasizing that meaningful urban development transcends physical structures. Urban development should go beyond constructing tall buildings and efficient transit systems—it should also prioritize fostering social and cultural networks that shape a city’s identity. In this context, the ground and lower floors of tall buildings play a vital role in activating streets and enriching the public realm, especially amid challenges related to urbanization, growth, and market volatility.

With the project site located anywhere in the world, participants are encouraged to explore and resolve the synergistic relationship between a tall building and its urban context. This includes examining how the building can be inspired by the cultural, physical, and environmental aspects of its site; how its program is shaped by both micro and macro site and urban conditions; and how the design responds to global challenges. Proposals should show evidence of a clear understanding of how considerations of structure, environment, servicing, etc. are as vital to the success of a tall building as the form, materials, aesthetics, etc.
