List of octagon houses

The style became popular in the United States and Canada following the publication of Orson Squire Fowler's 1848 book The Octagon House, A Home for All.

In the United States, 68 surviving octagon houses are included on the U.S. National Register of Historic Places (NRHP).

The earliest and most notable octagon house in the Americas was Thomas Jefferson's 1806 Poplar Forest.

[b] Of these, six are further designated National Historic Landmarks of the United States: Armour-Stiner House in the Hudson River valley in New York, which is perhaps the only domed octagon house in the world; The Octagon House in Washington, D.C. (which is actually more of a hexagon), where President Madison lived after the White House was burnt by the British; Thomas Jefferson's retreat Poplar Forest; May's Folly in Georgia; Samuel Sloan-designed Longwood in Natchez, Mississippi, still unfinished after its construction was halted by the American Civil War; and Waverley, also in Mississippi.

In 1958 Carl F. Schmidt published The Octagon Fad which attempted to inventory the Fowler-inspired homes, most of which were built prior to 1915 in North America.
