A houseboat (different from boathouse, which is a shed for storing boats) is a boat that has been designed or modified to be used primarily as a home.
Some houseboats are not motorized, because they are usually moored, kept stationary at a fixed point and often tethered to land to provide utilities.
In Europe, some of the finest and costliest examples of houseboats can be seen along the canals of Amsterdam, which even has houseboat hotels. Houseboats are very expensive in Amsterdam because of the limited number of moorings; this expense has reduced the likelihood that the approximately 2,400 families that live on the inner waters of Amsterdam will find themselves confronted by new neighbor boats. The Bloemenmarkt is a houseboat borne flower market along the Singel in Amsterdam. The town of Maasbommel is pioneering floating houses, with flexible connections for fluids and electricity; these are not primarily intended for travel, but rather to be safe against flooding.
