Abstract: An engineered wood structure is shown that can be placed in an aquatic or other environment. It is particularly useful in environmental enhancement efforts as a resting place for various avian and aquatic species. The structure is preferably made from small logs. A number of logs are placed side-by-side to form a deck surface. A single log is spaced apart from and generally centered below the deck logs. A pair of spaced apart struts depend from the lower surface of each deck log and are connected into the keel log to form a unitary structure.
