Building to West of Gate House and Butterley Company Works

This building, located to the west of the gatehouse at the Butterley Company Works, is an early 19th-century structure that has undergone later alterations. It is constructed of coursed squared stone with stone dressings and features a hipped Welsh slate roof with a projecting eaves band. The building is two storeys high and consists of four bays.

On the ground floor, there is a central doorcase that is now partly blocked with brick and has a 20th-century door. To the left of this doorcase are three segment-headed windows with stone voussoirs, although the central window is partly obscured by steps. To the right, there is a 20th-century window and a flight of iron steps leading up to a wide first-floor plank door that sits below a segmental voussoired arch.

An inserted doorcase with a plank door is located to the left at the top of another flight of steps, flanked on either side by two short windows beneath segmental voussoired arches, which have projecting sills. The sills have been significantly raised, and the windows below have been filled in.

The Butterley Works were established by Benjamin Outram around 1790 to take advantage of the local coal reserves. This building is included in the heritage listing for its group value context.
