Paris design collective ABF-lab unveiled one such urban farming idea in Agro-main-ville (food-farm-tower), a gigantic ziggurat-like greenhouse proposal for Romainville, Paris. Designed to maximize solar exposure, the food-farm tower eschews artificial lighting and could offer Parisians access to ultra-local healthy food with a minimal carbon footprint

Designed in collaboration with S2T, Atelier Altern Paysage, and Topager, ABF-lab's food-farm-tower proposal placed second in a national competition hosted by OPH Romainville. The 2,000-square-meter design has an estimated cost of 3.4 million Euros. The architects envision the proposal as a pilot project that could help popularize urban agriculture, raise awareness on quality food, and help improve attitudes towards environmental and social responsibility.
