In 1994 I crated a Japanese Zen garden in the village of Symondsbury / Dorset / UK.
It was done by the help of several of my martial arts students and other friends. the building of it took twelve months. The size was about 100 square meters and one had to enter via a small gate.

One inspiration to build the garden came by reading this book:
