With half of humanity now living in cities, there are compelling reasons to grow more food in them.  Urban farming has seen steady growth in recent years, so too has the green roof concept. 

The rooftop greenhouse concept takes the concept literally to new heights by making profitable use of the space above our heads.  Not only can we grow food crops and consume them in the building below, we can also make use of the greenhouse to heat the building during the day, and the building to heat the greenhouse at night.
