TR 04 SE BROOK THE STREET (east side)
4/61 Oasthouse about 30 metres west of Court Lodge
GV II
Oasthouse, now museum. Dated 1815. Red brick, with weather boarded upper floor with wooden cowl to roundel and plain tile roof to stowage. Two storey stowage with hipped roof, with wooden casements on each floor, and boarded doors in end elevation. Roundel with plate glass openings and datestone on north side. Interior: roundel of double ring type, the inner canted wall supported by parabolic brick core, now cut away to demonstrate construction. Fired by 4 furnaces (an unusually large number) to ensure even drying. Wattle and plaster lined cone. The stowage ground floor is contemporary with roundel, but the first floor and roof are timber framed and appear to be re-used from a late medieval hall house (stop chamfered joists, jowled posts, re-used soot blackened rafters with evidence of collar purlins, i.e. crown-post roof origin). Even the metal supporting straps to some timbers are C17 or C18. (See Traditional Kent Buildings, Vol. 1; see also Wye Local History Magazine, R.F. Farrar, The Oasthouse at Court Lodge, Brook).
