Wood or timber "decking" can be used in a number of ways as part of garden landscaping, to extend living areas of houses, and as an alternative to stone based features such as patios that may generate a lot of heat. Decks are made from treated timber for the sub floor and various timbers for the decking itself.
A pergola is a garden feature forming a shaded walkway, or entertaining area for the great outdoor barbeques. The pergola may also be an extension of a building, or serve as protection for an open terrace. Free standing pergolas are not attached to a home or another structure to provide a sitting area that allows for a breeze and some light sun.
