Building the deck near to the ground helps protect the finished building from wobbling. In place of the ledger board, I built a cantilevered deck with the joists supported by two enormous parallel beams (also known as girders) running parallel to the house wall. The weight of the deck is transferred through the girders into the foundation, which prevents any movement of the house when it rains or snows. The main advantage of this method is that it doesn't require any special tools for construction and the space underneath the deck is used instead. The disadvantage is that if someone falls off the deck they can be seriously injured or even killed because there's no way to get them down safely. Also, the structure is not as stable as one might hope - especially if you add any furniture to it. Finally, the whole thing looks rather ugly when painted red. But these are minor issues compared to the protection it gives your house. This system is commonly used for large, outdoor entertainment centers such as bars or man caves. It's also useful when you want to build an extension onto your house and don't have enough room under the existing roof for proper support beams. In conclusion, this type of construction is used when you want to use part of your yard for something other than lawn or garden.
