Aller Farmhouse Including Parallel Range at Rear and Hand Pump in the Alley Between

Aller Farmhouse, which includes a parallel range at the rear and a hand pump in the alley between, dates from the 16th and 17th centuries, was reroofed in the 18th century, and restored in the 19th century. It is constructed of red sandstone random rubble with quoins and features slate roofs. The gabled cross wing has a barge board and a stone stack that rises from the eaves on the left, while there is a large external stone stack on the right gable end and brick stacks at the gable ends of the rear range.

The layout is not entirely clear without an internal inspection, but it includes a parallel range at the rear with two cells and separate entries, linked by about 1.5 metres of wall to the main block. There is a cross passage with a single cell on the right, a stair turret at the rear, and a left projecting crosswing with two cells. The building is two storeys high with a façade of one to three bays.

On the first floor to the right, there is an early 19th-century leaded casement window with quadrant stays. The left gable end features a three-light hollow chamfered stone mullioned window under a square hood mould, with a similar pair of windows below it and another pair to the right of the entrance. These windows have all been partially renewed in the 20th century. The entrance features a nine-panel door with a wooden arched fanlight in a brick surround and a pentice porch on shaped brackets.

The interior has not been viewed, but the 19th-century hand pump is located in the alley between the main block and the rear wing. The rear wing is said to contain fireplaces at the gable ends, one of which has a bacon curing chamber and the other a tile-lined oven. The interior features chamfered beams with step and run-out stops and evidence of a jointed cruck roof prior to the 19th-century reroofing. The main block is reported to be without datable features. Historical records indicate that a house and chapel existed on this site prior to 1197, and a detailed survey was conducted in 1507.
