STUDIES OF FUNCTION + FORM

Tall buildings of the future need to be highly efficient in how they use materials and energy. With every project, we work to optimize building facades, systems and performance to create greener, smarter, more economical high-rises. These tall buildings can shrink a city's environmental footprint while still helping to define its identity and promoting economic growth. The following projects demonstrate HOK’s commitment to exploring the limits and possibilities of tall building design.
