Brazilian design studio Rosenbaum collaborates with TV shows Caldeirao do Huck in a segment called Lar doce Lar (Home Sweet Home), which helps families in need re-designing their homes to improve their lives and self-esteem. In its latest work for a family living in the outskirts of Sao Paulo, the firm included this neat vertical garden made from recycled PET bottles. Although the idea is cool in itself, it's so much better knowing that it's part of a project to improve the lives of three women (mother and two daughters) that live in a one bedroom home with an income of 200 Reais (130 US Dollars) a month.

Putting together an urban farm was not the designer's whim either: the women already had an eco conscience and grew in small containers made from recovered food packaging. The arrangement is of course thought for vegetables that don't take a lot of space to grow, like spices and medicinal herbs. Its structure is pretty self-explanatory from the pictures, but the response from the public was so positive that the designer published a little tutorial showing how to cut and hang the bottles.
