Shirriff-houses were crude building used by the Shirriffs after Lotho Sackville-Baggins took control of the Shire and expanded the Watch.
At the west end of Frogmorton was a poorly constructed one-story brick building with narrow windows, which served as the barracks of the First Eastfarthing Troop.
All the Shirriff-houses were torn down before the end of T.A. 3019 (S.R. 1419).
