Once Lafferty hit upon the Elephant idea he enlisted the aid of a Philadelphia architect named William Free to design this unusual structure he felt would attract visitors and property buyers to his holdings. The Elephant was constructed in 1881 by a Philadelphia contractor at a reported cost of $25,000, which at the time was a considerable amount of money. Lafferty always claimed that before the work was finished the cost Skyrocketed to $38,000.
To protect his original idea, Lafferty applied for and received a patent from the U.S. Government. He made his original application June 3, 1882, and received the patent, No. 268, 503, on Dec. 5, 1882. In his application Lafferty stated: "My invention consists of a building in the form of an animal, the body of which is floored and divided into rooms ... the legs contain the stairs which lead to the body ...". Lafferty also included a paragraph which stated the building "may be in the form of any other animal than an elephant, as that of a fish, fowl, etc." What his intentions were in adding that paragraph have never been clear. He never attempted a building in any of the forms mentioned.
It is believed that most of the materials were brought to the site by boat although there was rail service of a sort in the upper part of Absecon Island where the infant resort of Atlantic City was just getting underway. By 1881 Lafferty was placing advertisements in area and Philadelphia newspapers offering building lots in "fast booming South Atlantic City". Lafferty eventually extended himself too far in his land deals both at the Jersey Shore and in New York and by 1887 sought to unload his South Atlantic City holdings. He offered the Elephant and other property for sale and found a willing buyer in Anton Gertzen of Philadelphia.
Lafferty died in 1898 and is buried in the family vault, in the cemetery of St. Augustine's Catholic Church, one of Philadelphia's oldest churches (1796), which still stands in the shadow of the Benjamin Franklin Bridge.
There is also a restaurant in it now.
