The landscape was inspired by a mountain setting by the sea. A stunning stepping stone path is one of the defining features found on this property and was inspired by the intimacy of a mountain path. A gentle climb through the woodland part of the garden will lead you to a “mountain peak”. There you will meet the gravel path representing a stream that will guide you to an authentic pondside tea house.
