The William Thompson Jr. House, at 10 W. 400 North in Beaver, Utah, was built around 1880 by Scottish-born local stonemason Thomas Frazer.

[1] It was built as a one-story black rock cottage with two rooms, and a symmetric window-door-window front facade..

It displays three of Frazer's characteristic elements: use of ashlar stonework on the front facade, use of beaded white mortar joints, and use of a Greek Revival-style cornice.

The additions, which are also of a historic date, extend backwards from the rear of the house, leaving the original two room rock cottage with unimpared architectural integrity.

He frequently built two room rock cottages, with medium-pitched roofs and Greek Revival style cornices.
