happiness comes from heavean by marjanco jakimovski from switzerland

In the big cities there is not much green spaces but lots of buildings. Generally the roof isn't use. So my concept goes straight there to make this place a new living space for all people who's living in the same building. A new place to meet people, to have fun, playground for children, to barbecue, to relax and even to grow your own vegetables. This can be the future of the cities to have more fun and a little green attitude and have fun.
