Gardens by the Bay, Singapore
This immersive, slightly trippy garden fantasyland, opened in 2011, is made up of various botanical attractions designed as sustainable public spaces. Highlights include the “Supertree Grove,” a forest of 16-story-high man-made structures covered with living plants and boasting photovoltaic cells that harvest solar energy (the trees are spectacularly illuminated at night), and the Flower Dome, the world’s largest column-less greenhouse—air is cooled at the lower occupied zones through chilled water pipes in ground slabs, while warm air is vented out the top. The conservatory is filled with blooms from all over the world, including a flower-filled field, and constructed from an intricate steel grid and 3,332 glass panels.
