TQ 64 NE CAPEL MAIDSTONE ROAD, WHETSTEAD
2/271 Oasthouse approx 20m north of Stone Castle Farmhouse 11.1.90 GV II
Oasthouse. Mid/late C19. Mostly red brick but the north front and west end are timber-framed and clad with weatherboards; peg-tile roof.
Plan: Oasthouse. Stowage on a rough east west axis facing north. 3 hop kilns, 2 on the south side and a taller one on the east end.
Exterior: The north side of the stowage (the front) was not available for inspection at the time of this survey. The west end contains a cart entrance containing double plank doors. The stowage roof is gable-ended. The hop kilns are circular in section and have brick dentil eaves cornices. All have tall conical roofs with cowls.
Interior: Not inspected.
Despite inadequate access this appears to be a well-preserved unconverted oasthouse which forms part of an attractive group with nearby Stone Castle Farm (q.v.) and its garden walls (q.v.).
