A Greenhouse Made of SteelS

Who said nature has to be pristine and untouched by technology? The Orquideorama is a giant steel-and-wood structure recently built in the middle of a more traditional botanical garden in Medellin, Colombia. It consists of a series of modular, honeycomb-like "flower-tree" structures. The hexagonal "flowers" actually serve an important function—they collect rainwater and distribute it evenly to the flora beneath. This beautiful, functional structure could become a common substitute for antiquated greenhouses. Image by Sergio Gomez [Inhabitat]
