May 2, 2013 — Can urban farms be fun as well as functional? As interest in producing food in cities grows, so do visions for hybridizing function with aesthetics in innovative and entertaining ways. Among the ideas that have taken root in architects’ imaginations are a 132-story dragonfly-shaped vertical garden powered by the sun and wind; a geodesic greenhouse whose angled panels direct winter light to plants throughout the interior; plant-mimicking towers with “stems” that carry water to food-producing plots arrayed like leaves; a combined apartment building, greenhouse and chicken farm; and a literal food pyramid. They’re not all just pie in the sky, either: One such “farmscraper,” a 175-foot-tall greenhouse planned for Linköping, Sweden, is scheduled to begin producing food as early as next year.
