In 2008 the building was subject to a historic building survey. Report not sent to HER team so no further information (3)

In 2010 Archaeology South-East carried out a survey of the building. The building was probably built in the late 16th century as a garden pavilion or banqueting house. It became a house in the 18th century and was extended at this time. During the use of Sissinghurst Castle as a prisoner of war camp in the 18th century this building was probably the main guard room. During the use of the site as a workhouse, this building was used by the bailiff. It is known as the priest's house as it is thought that a chaplain could have lived in the building in the 17th century. There is no evidence for or against this tradition. (2)
