The Urban Skyfarm is a vertical farm design proposal for a site located in downtown Seoul, right adjacent to the Cheonggyecheon stream which is a heavily populated dense urban area within the central business district. Through lifting the main food production field high up in the air, the vegetations gain more exposure toward the natural sunlight and fresh air while the ground level becomes more freed up with nicely shaded open spaces which could be enjoyed by the public. The bio mimicry of the tree form gives many structural and environmental advantages to form a light weight efficient space frame which could host diverse farming activities. The four major components which are the root, trunk, branch and leaf each have their own spatial characteristics which are suitable for various farming conditions. While the upper portions provide open to air farming decks for medium based vegetations, the lower portions enclosed by the structural skin provide more controlled environments for solution based leafy productions. During daytime the photovoltaic panels generate electricity to be used for night time lighting and heating to support farming. The Urban Skyfarm creates a mini ecosystem which brings balance back to the urban community.
