In the traditional Japanese Garden everything leads away from the main house, or if it is a tea garden, the teahouse. To the Japanese, sighting a garden in an area un-associated with any primary structure is like a chicken without a head.
If there is to be a teahouse included somewhere in the garden layout, it must have its own separate garden; hence the term middle garden for the space between the main house and the tea garden .The middle garden , like the tea garden can be designed in any of the traditional Japanese garden styles.
There is usually is a roofed gate separating the middle garden from the teahouse garden. This indicates the beginning of a new mood or experience. It is usual to see a basin stone or other vessel, placed here with a bamboo dipper providing guests the opportunity for ceremonial cleansing before advancing into the tea garden and takeing part in the tea ceremony.
The tea garden is usually much smaller than the middle garden, as the teahouse is to the main house. The style in tea gardens can vary considerably depending upon what era they are designed to represent.
I refer to my own tea garden (the teahouse not yet constructed) as my " Zen Garden" because it is being constructed to represent a type of garden prevalent in Japan during the Kamakura period (14th-15th century) when Zen had its greatest influence on garden design.
