eVolo Magazine has announced the winners of its 2019 Skyscraper Competition. Now in its 14th year, the annual award was established to recognize “visionary ideas for building [high-rise] projects that through [the] novel use of technology, materials, programs, aesthetics, and spatial organizations, challenge the way we understand vertical architecture and its relationship with the natural and built environments.”

This year, 3 winners and 27 honorable mentions were selected from a pool of 478 entries. Among this year’s winners is a vertical city district in Belgrade that serves as a landfill, a skyscraper that cleans air, and a nature reserve.
