Description
Trowley Bottom Farmhouse is a farmhouse that dates from the 17th century or earlier, with a late 18th century north parlour block and a mid-19th century single-storey south wing. The building features a timber frame with painted brick infill in the central section, painted brick in Flemish bond on the north parlour, and painted coursed flint with brick dressings on the south wing. It has steep old red tiled roofs, with a grey roof on the parlour block.
The farmhouse is a long L-shaped structure facing west, generally two-storeys high, set back from the road with a yard at the rear. The central part of the west front has three bays of exposed framing with 8:6:4 panels and a projecting southwest corner post, suggesting that the building may have originally extended further south. Each bay has one window with small-panes casements, while the ground floor features three 20th century flush casement windows. There is a plank door with a dripboard.
The projecting north parlour block has one window on each floor, consisting of a 12-light flush casement above a three-light window with a segmental arch. A large chimney is located at the centre of the north gable of the central block, now enclosed in the parlour wing, which has its own rear-wall chimney. The lower rear wing extends behind the parlour, and the three-window lower south wing has a small chimney in the front roofslope.
