The Stephen B. Quillen House is a two-story, wood-frame house in the Queen Anne style with a wraparound front porch set over a rusticated limestone foundation. It is located on a corner lot at Church and Lively streets in one of the original neighborhoods of the town of Lebanon. It was one of the first houses built in the neighborhood. The house has a steep and irregular hipped roof with lower cross gables, cutaway bay windows, and simple door and window treatments. Inside, the house retains all of its refined red oak woodwork. Local builder and businessman Nathan W. Easterly constructed the house in 1912 as a speculative business venture. Six years later, Russell County attorney and former Lebanon mayor Stephen B. Quillen bought it.
