Rooftops make great gardens, especially in dense urban environments where every available space has been utilized for living and for commercial purposes. In many cities around North America, Asia and in Europe too, where outdoor space is scarce, architects and builders are turning rooftops into playgrounds with swimming pools and vegetable gardens. But in Jakarta, Indonesia, one developer has converted the rooftop of a shopping mall into an entire suburb of sorts with houses, paved streets, a tennis court and lush greenery.
