Redstone is a historic building located in Dubuque, Iowa, United States.

[2] The 2½-story brick structure with red sandstone trim was designed by Thomas Carkeek in the Richardsonian Romanesque style.

The elements of that style are found in the round arch window openings, the use of rough limestone for the lintels, and its heavy mass.

The terracotta friezework on the cornices over the bay window, the tower, the corner gables, and the Corinthian-style capitals on the porch columns reflect Neoclassical influences.
