A former 18th/19th century two-storey brick cottage, constructed between 1769 and 1841, is incorporated into the current building. This cottage can be seen on the 1841 Tithe Map and the corresponding tithe approtionment describes the site as a 'cottage and garden' rented by John Allchin. The southern and western walls of this building survive in part to first floor level and are incorporated into the south-eastern corner of the modern building. The original chimney-stack survives, as do its fireplaces. The first reference to the use of the site as a pub is in the 1861 Census, when a brickmaker was listed as selling beer from the property.

At some point between the 1841 Tithe Map and the construction of the modern building in around 1872, a formerly detatched two-storey structure was constructed on this site. This structure was incorporated into the present building, though much of the brickwork is concealed by later alterations and extensions. This building appears to have been used as a beer house, and is labelled as such on the second edition OS Map (1897-1900). (1)

The existing building was constructed at some point shortly before 1872. The two existing structures on the site were linked by the addition of the former bar area. Unlike the ground floor, where little of the original layout remains, many of the first floor rooms retain their original layout. An extension was added to the rear of the building in around 1900 to incorporate a new kitchen and WCs, and later additions were made in the later 20th century to expand these facilities. A new restaurant extension was also added in 2002. (2)
