Llansor Fawr (Great Llansor)

Llansor Fawr (Great Llansor)

This is a two-storey house with attics in part, built of thinly coursed red sandstone rubble with dressed quoins and ashlar window dressings. The building was probably originally plastered. The roof is Welsh slate with some corrugated asbestos sheeting at the rear. The house follows a three-room plan with a service wing projecting forward at the left. This service wing was originally for domestic use but was converted to a granary and stable in the mid-nineteenth century. There are also a projecting stair wing and kitchen lean-tos at the rear of the main range.

The entrance elevation of the main range has three bays. A central porch, dating to the mid or late nineteenth century, features a gothic head and a bargeboarded slate roof. On either side are tripartite sashes with 1 over 1 flanking 2 over 2 panes, set beneath elliptical brick heads. The upper storey has three 3-light stone mullioned casements with pointed heads. The roof is steeply pitched with truncated paired diamond-set chimneys to the right gable. The right gable end is not visible.

The advanced service wing to the left has floor levels below those of the main range. Its ground floor contains a single sash window with 4 over 4 panes. The first floor has two mullioned windows with pointed heads and drip-moulds: a 4-light window to the left, now blocked and possibly reset, and a 3-light window to the right with a relieving arch above. The walling above this floor is blank and shows signs of disturbance, possibly related to the Victorian conversion to a granary which may have required heightening. Beyond this, the wing descends to what appears to be its original height for one further bay, which has a 2-light window with pointed heads and sunk spandrels to each floor. Both sections of the wing have steeply pitched roofs, but no external evidence of chimneys. The gable end has no ground-floor window, a 3-light window with relieving arch on the first floor, and a blind and partly damaged 3-light window in the gable above. The left quoin of the gable shows neatly squared stones, with the upper ones in long-and-short work, whilst the right quoin lacks this detail and displays a crack running from top to bottom on the front wall.

The rear elevation of the main range includes on the left a Victorian lean-to covering the entire rear wall just below the eaves, with a tall brick chimney. A large hall lateral stack with paired diamond-set shafts has its lower part hidden by a late nineteenth or early twentieth-century lean-to, which contains a 3-light casement and a Welsh slate roof. A projecting gabled stair wing with squared quoins has a 3-light replacement timber casement between ground and first floor, and a 2-light window in the attic. The right return shows disturbed walling where a probably late nineteenth-century lean-to, positioned in the angle between the stair wing and the main range, was removed around 2000. A large gabled dormer with a 2-light casement rises in the attic of the wing, and a tall rebuilt stack sits on the ridge where the wing meets the main range. A modern 3-light casement is present on the ground floor of the main range to the right.

The right return has a large 5-light window on the ground floor (dating to around 2000) below a hidden joist. A corbelled stack serves the first-floor room above, flanked by 2-light casements. Two blocked garret windows appear in the gable. The rear of the wing has an external staircase leading to a gabled porch serving the first-floor granary, with a door to a storeroom below. The end section of the wing has a plain door to the lower room.

The interior was only partly available at the time of resurvey, and late twentieth-century alterations were evident. A short flight of stairs winds around a solid core. Cross beams have roll and ogee mouldings. The post-and-panel screen is no longer in place, though part of it has been incorporated as wall panelling.
