Description from record TQ 57 NE 101:
Referred to variously as the Coach House, the Stable Block and Ivydene. This building dates to c1833 when the owner of Ingress Park, James Harmer began work on his new house, Ingress Abbey. It was connected to the east wing of the house via some Portland Stone steps. The 2 storey building has two wings joined by a central projecting gable. The ground floor had limited stable and coach accomodation, with residential accomodation on the first floor. It is of similar construction to the main house, with ragstone walls, clad externally with Portland stone ashlar in a Gothic vocabulary.The building was set back against the scarp of a chalk pit, so that only the first floor of the western elevation is visible above ground [1and 2].
An archaeological investigation was undertaken in the area between the coach house and Ingress Abbey, during groundworks necessary for the installation of a disabled access lift. No significant archaeological features or deposits were observed. The area appeared to be made ground, associated with the construction of Ingress Abbey in the early nineteenth century [3 and 4].
