Letterboxes have been my interest since I first entered the village and my system mapping maps out the location of the letterboxes, the route of the postman and the relationship between letterboxes and their relative properties. By mapping a total of 300 letterboxes and its relative owners property in the village, a distribution pattern of letterboxes is revealed. Some letterboxes are gathered due to topography, property and , of course, location.
By careful analysis and observation, different typologies of letterbox gathering are found. Invisible communities formed by the gathering of letterboxes are revealed by such maps. This kind of community cannot be seen in any other kinds of map and the specialty of it triggers me to produce the following site design strategy.
