Blackwall Farmhouse

Blackwall Farmhouse is a building that has been converted into four dwellings. It likely dates from the early 17th century and consists of two separate builds that were subdivided and altered in the late 18th to early 19th century. The structure is made of rubble brought to course, rendered or painted, and features a stone slate roof. It has a hall and cross-wing plan with a through passage, standing two storeys tall and comprising three bays, with a gabled cross-wing on the left.

The ground floor windows are double chamfered mullioned with arched lights, while the first-floor windows are single-chamfered mullioned, unless otherwise noted. In the cross-wing, there is a four-light window flanked by plain single lights, and on the first floor, there is a three-light window that has been altered to a two-light window with an inserted plain window to the left and a dripstone above.

In the main range, the left bay features a chamfered shallow segmental-arched doorway to the right of a three-light window, with a four-light window above. The central bay has a 19th-century doorway to the right of a five-light transomed window, with a four-light window above that has been altered to a two-light window. The right bay contains a 19th-century doorway to the left of a four-light window with square-headed lights beneath a remnant of a string course, and a similar window under a hoodmould above. The main range has end stacks and one ridge stack between the left-hand bays, while the cross-wing has a lateral stack on the left.

At the rear, the through-passage doorway is chamfered and has a Tudor arch within a gabled porch that features a segmental-arched doorway and inner stone benches. Other openings date from the conversion and include doorways to the left and right, each positioned to the right of a three-light flat-faced mullion window, with a similar four-light window above, each having one light blocked. The cross-wing has a hipped roof with a crocketed finial at the apex of the hip, which descends low over a 19th-century extension.

Inside No. 3, there is one stop-chamfered beam and a corniced fireplace that date from the conversion. No. 1 was in a state of dereliction at the time of resurvey.
