Nature shows us the best architectural examples: mushrooms, trees, ant hills and lawns are beautiful in color and texture. Human beings are part of nature. They feel themself the best in a structure that is relatated to nature. The gauge connecting between man and nature is the golden ratio. This size ratio has been used since ancient times, like the geomantic and the Greek and Roman architecture, and can be found in nature: relations between the partitions in a cochlea and petals of a flower. Architecture that works with the same proportions and patterns as nature responds to the connection between human and earth, playing with the laws which our life is subject on earth.
