There has never been an over-all design. I don’t work like an architect who draws a plan, then goes ahead to execute it. This might not be fun. Instead, for some twelve years now,new projects for planting and building re inverted each year. Thus, the work is additive or constructive. I try very hard to make the new features fit together with the earlier ones, even to the point of giving an illusion that the whole thing was designed at the start.
