Bill Gates designed and owns a mansion that overlooks Lake Washington in Medina, Washington. The mansion incorporates technology in its design. In 2009, property taxes were reported to be US$1.063 million on a total assessed value of US$147.5 million. Design and features The house was designed collaboratively by Bohlin Cywinski Jackson and Cutler-Anderson Architects of Bainbridge Island, Washington. The mansion is a modern design in the Pacific lodge style, with classic features such as a private library with a dome-shaped roof and oculus. The house features an estate-wide server system, a swimming pool with an underwater music system, a gym, and a dining room. In popular culture The house was made fun of in Dilbert in January 1997 when the lead character was forced to become a towel boy after his failure to read an end-user license agreement over purchased Microsoft software. Some online news articles call the house Xanadu 2.0, a reference to the motion picture Citizen Kane, which was itself a reference to the opening lines of Samuel Taylor Coleridge's classic poem Kubla Khan. The name Xanadu 2.0 is an example of "citogenesis".
