Architectural feats that are so out-of-this-world that you won’t believe they exist.
  1. Sky Pool

    London’s newest swimming pool is not for the faint of heart. The British architecture firm HAL is currently working with developers Eco World Ballymore on the 2,000-home Embassy Gardens residential development, where two buildings will be linked by an all-glass swimming pool measuring 90 feet long, 19 feet wide, 10 feet deep, and suspended more than 100 feet above street level.
  2. Beyoncé-Inspired Tower

    Though Beyoncé’s persuasion has yet to build a nation, it has inspired the construction of at least one building. The curvaceous new Premier Tower, located in Melbourne, Australia, and designed by the architecture firm Elenberg Fraser, was modeled after the singer’s famous form.
  3. 3D-Printed Office Building

    Dubai’s newest office building will not be a traditional construction project. The United Arab Emirates has partnered with WinSun Global—a joint venture between Chinese 3-D–printing tech company WinSun and architecture and engineering firms Gensler, Thornton Tomasetti, and Syska Hennessy—to 3-D–print the structure.
  4. A Manta Ray–Shaped Research Center

    French architect Jacques Rougerie has drawn up plans for a floating research center that mimics the appearance of a massive manta ray. Dubbed the City of Meriens, Rougerie’s creation would house an international oceanographic university that would drift the seven seas, accommodating thousands of researchers, teachers, and students over extended periods of time.
