The Kellogg House is a historic building in the Columbia-Tusculum neighborhood of Cincinnati, Ohio, United States. Built in 1835, it is a two-and-a-half-story building with two prominent chimneys on the ends. The weatherboarded walls rest on a stone foundation and are covered by a metal roof, which rises to a high gable on each end. The building's architecture is a mix of the Federal style with many vernacular elements; it has been recognized as one of the area's best examples of transitional architecture. Some of the distinctive features of the Kellogg Building are the small brackets that support the simple cornice, two wings attached to the rear, and the two enclosed porches on the facade. Inside, the main hallway is ornamented by such features as intricate fretwork and multiple pillars.
