The Isaac H. Lionberger House at 3630 Grandel Square in Midtown St. Louis, Missouri, is the last private residence designed by noted American architect Henry Hobson Richardson.[1] Designed in 1885 - 86, the building was built after Richardson's death. It was built for Isaac H. Lionberger, a well-known St. Louis lawyer who later became Assistant Attorney General of the United States.
The Lionberger House became a St. Louis Landmark in 1975. In 2005, the house was restored and divided into office and residential space.[2]
