Blackwall House

Blackwall House is an early 17th-century house with significant alterations in 1736 and the mid-19th century. The building is constructed of ashlar gritstone with plain tile roofs, stone coped gables featuring kneelers, and ridge and gable end stone stacks. It has an irregular plan based on a square shape with west and east wings. The house extends over two storeys plus attics. The east elevation displays three blocked two-light mullion windows dating from the 17th century, two of which have dripmoulds. The main, symmetrical south elevation features three gables. It was likely refaced in 1736, as evidenced by a dated lintel above the basement door on the west elevation, and given four Venetian windows (two on each floor), a central round-headed window to the first floor, and similar windows in the left and right gables, all with glazing bar sashes. A central gabled porch with a keyed round arched opening was added in the mid-19th century, along with a low, double-sided stairway with a stone balustrade and a narrow, shaped gable. The north elevation is similarly dated to the mid-19th century, adopting a Tudor/vernacular style with flush chamfered mullion windows with casements. The house was originally built by the Blackwall family before 1623.
