The Brill Octagon House is a historic octagon house at Capon Springs and McIlwee Roads in Capon Springs, West Virginia. It is a two-story wood-frame structure, that is actually cruciform in shape, but is given an octagonal appearance by the presence of two-story triangular porches that join the corners of the cross. The house was built about 1890 by one of a father-son pair, both named Elias Brill. The elder Brill, a more likely candidate as its builder, was a farm laborer, and was according to family lore guided in the building's design by an architect who was a summer guest at the Capon Springs Resort. The design is apparently a throwback to the briefly popular octagon house movement led by Orson Squire Fowler in the 1850s. The house was listed on the National Register of Historic Places in 2016.
