The public space in the middle of Singapore’s recently completed Marina One complex provides genuine respite. Above the district of concrete-and-glass towers, the noonday sun beats down relentlessly. But even though temperatures in this tropical city regularly tip to over 90 degrees Fahrenheit and humidity often hits 95 percent, it is a refreshing experience to walk through the center of this new development. Here wood and stone paths are surrounded by lush plants and trees that sway gently in an unexpected breeze.
