This enclosed back garden uses tree ferns to create a dramatic year-round effect. The levels steps up gradually from a cast concrete terrace to a small sandpit and kids garden at the far end of the garden. The journey between the two is through a mass of delicate grasses and lumpy mounds of box. The idea of the place is that even within a relatively small space there can be a liberating sense of other worldliness about the garden experience. The moment you cross the threshold you are in a different world.
