When you type in "deck design plans," your search results will include deck plans for in-ground pools. This is not a trick or an example of poor categorization on the part of the webmaster. In the world of landscape design phraseology, a "deck" refers to a raised platform-like structure that is attached to a house or a pool. The term "decking" refers to the stone or masonry that surrounds an in-ground pool. Since all deck design plans include a list of materials required to build the deck, that list often includes decking. It does not make any difference whether you plan to build a deck off your house or pool, your search will invariably return web pages that talk about in-ground pools.
