The 5th and 6th level will be the Orchard open to the public, administration where the office are located.
The 7th & 8th level will be supermarket. It will guarantee full freshness than those imported from foreign suppliers.
The 9th level will be a musuem where the public will learn how eco farms work.
The basement will be a Bottling facility. Where the "sweat from plant" evaotranspiration will be collected and convert to drinking water.
