Cactus, Skyscraper Size
A skyscraper in the shape of a cactus is planned for the new Ministry of Municipal Affairs and Agriculture in Qatar. Designed by Aesthetics Architects in Bangkok, the giant structure doesn't just look like a cactus. The shades around the building open and close in response to the heat, like cactus cells, making the cactus tower a true example of biomimicry.
There could not be a better city for cactus-inspired architecture. Qatar is in the middle of the dessert with daily temperatures near 100°F.
A botanical garden is designed for the base of the cactus tower. The design photos show grass and trees that would grow in a moderate climate, so I guess it won't be a cactus garden.
