Octagon houses usually have these features:
- Octagonal or rounded shape, usually (although not always) with 8 sides
- Porches, usually one-story
About the Octagon Style:Historians often credit writer Orson S. Fowler for the innovation of the unusual and rare Octagon style. Fowler believed that Octagon houses increased sunlight and ventilation and eliminated "dark and useless corners." After Fowler published his book The Octagon House, A Home for All, plans for Octagon style houses were widely circulated.
However, Fowler did not actually invent the idea of octagonal design. Thomas Jefferson used the octagonal shape for his summer home, and many Adam and Federal style homes included octagonal rooms.
Only a few thousand Octagon houses were built, and not many remain.
