Building recording and assessment by PAYE Conservation on the Dietterlin-style entry gate pillars prior to their repositioning and restoration. The pillars are assessed as being of typical Jacobean style, although they are recorded in the listing as being 18th century in the Mannerist style. Previous 20th century repairs, using inappropriate materials, were found to have accelerated their deterioration. The gates and pillars are recorded as present in the 1680s (SyAC 50, 102).
