The Siemer House was located on Lot 1, Block 17 of the original town of Davenport, Iowa, United States, which today is the west side of downtown.

J.C.F Siemer was a brick mason who immigrated to Davenport from the German states of Schleswig-Holstein.

The Siemer House was a two-story brick building on a stone foundation.

This late Victorian structure featured details that evoked the Italianate style: a cube-like mass, a bracketed metal cornice, the tall, narrow profile of the fenestration, and the centralized entrance.

[2] The windows were symmetrically placed on the façade with five on the second floor and two flanking the entrance on both sides.
