Octagon Style Mouldings

Octagon house mouldings reflect the variety of architectural styles applied to this distinctive eight-sided house form. Popularized during the mid-nineteenth century, octagon homes incorporated trim ranging from simple vernacular boards to detailed Greek Revival, Italianate, and Victorian profiles. Their millwork follows the decorative character of the individual house rather than a single set of shapes unique to the octagonal plan.

Selecting trim for an octagon interior begins with its existing architectural details. Restrained casings and baseboards can support a simpler composition, while layered cornices and more elaborate surrounds suit richly ornamented rooms. Coordinating the profiles, proportions, and level of detail helps create continuity throughout the home’s unconventional layout.
