The David and M. Maria Hughes House is a historic building located in Williamsburg, Iowa, United States.

The brothers became wealthy as the result of a building boom in town after the arrival of the Chicago, Milwaukee, and St. Paul Railroad in 1884.

Because of poor eyesight, Hughes retired the year the house was completed, and he sold his share of the business to his brother.

[2] The Cedar Rapids, Iowa architectural firm of Dieman and Fiske designed the Hughes' house, and it was constructed by local builder Will Long.

It features a wraparound porch, a hipped roof with a front dormer and cross gables, and a corner tower with a finial.
