Jordan sold the house in 1988 to a friend who continued building on the site, adding to the collections of knick-knacks and exhibits featuring authentic pieces, reproductions, and specially-made examples of everything. The most recent addition is the "Spirit of Aviation", a collection of large model airplanes in a themed room. Another exhibit, the "Transportation Building", is under construction, but visitors can walk through and view the work in progress. In the same year, the "Wisconsin State Journal" published a four-part series on "The House on the Rock", which reporter Marv Balousek later expanded into a self-published book entitled "House of Alex." According to Balousek, Jordan Sr. hired "drunks and bums" from the Madison streets to help blast the rock. Balousek says that according to Sid Boyum these workers were sometimes paid with whiskey and sometimes by check, but that Alex Jordan Jr. destroyed the cancelled checks later to further a myth that he had personally built the house himself.
