The design of any garden can be affected by the nature of its boundaries but also in turn the design can influence the boundary. Fencing and gateways provide privacy, keep loved ones safe and intruders out, create shelter for wind sensitive plants, create niches, screen unattractive structures or views and provide an element of surprise within the garden itself. Garden furniture such as pergolas form a shaded walkway, passage or sitting area whilst smaller furniture provides interesting ornamental features.
