Urban farming is not a new idea, it’s such a great idea that it is often forgotten though. A solution to transporting food and improving urban air quality is literally under our feet, and can soon be over our heads. There is an ever growing need for using buildings in cities as farms and more companies are now behind the idea. Skyscrapers as farms just sounds cool!

Not to mention locally-grown produce for the residents of central London, Manhattan and Tokyo, eliminating the environmental costs of transport (with fresher lettuces to boot).
Skyscraper farms can operate year-round with artificial lighting, so, on average, one indoor acre is the equivalent to between four and six outdoors, and companies are vying to reap the financial rewards that come from this increased efficiency.
