Decking, which has been common in the United States and on the Continent for years, is a comparatively new introduction in the United Kingdom, even though the step between it and a wooden balcony is a small one. In fact, decking can be used to create a balcony garden where there was no usable space before. But it is not necessarily tied to a building, for it can be used as a surfacing material at ground level.The uses of decking really comes into its own when used in conjunction with a property on a hillside, where, raised on posts, it can be used to create a level platform on the side of the building facing away from the slope. The deck makes the transition out from the elevated first floor, and steps from the deck lead to ground level. This type of decking is often the only feasible way of creating a level space outside the house. They are also a good choice for roof gardens being lighter than concrete or stone.
