Perhaps you wanted to extend your kitchen a few feet? Or put an extra bedroom in for guests? Most square footage increases in homes are for very pragmatic reasons. In Telluride, CO, homeowners wanted a bowling alley as a Christmas gift, but still had a long narrow space to fill up in order to make the extension of their home both practical and aesthetically pleasing. They chose an indoor pool, and most unusually, an indoor shooting range to fill the long narrow spaces.
