Dense planting slows the flow, while water is also captured and stored for later use. After heavy rain, the elevated deck and mound – linked by a bridge over a central swale – provide both habitable places for people, and well-drained soil for the plants that need it.
The swale forms a stream, channelling rainwater into a feature pond where it can gradually soak away, while large tanks double as ornamental ponds which store water for later use, and can be discharged ahead of further rain, using smart-technology.
The planting is green and lush, with pops of jewel-colours, yet it is as tough as it is beautiful, and appropriate for the range of soil conditions. A large apple tree demonstrates the value of slopes for drainage, while a range of pond and bog plants are well adapted to varying degrees of water inundation.
