The Allen House is a historic building located in Dyersville, Iowa, United States. T.F. Allen was a land speculator and developer who had this house built in 1857, which was the peak year for building in Dyersville. That year the town was the terminus of the Dubuque and Pacific Railway. Thirty houses were built in the town that year, and others were under contract. Within a year, the railroad had expanded further west, and the town was in an economic depression exacerbated by the Panic of 1857. There is no mention of Allen or his family in Dyersville in the 1860 United States Census.
