Description
Llanddwywe Farm is a farmhouse with an attached L-shaped agricultural range, dating from the 18th century. The farmhouse is two storeys with attics, and has a storeyed rear wing and a single-storey wing added later. The front and side elevations are pebbledashed, while the rear of the agricultural range shows coursed rubble stonework with large stones used as quoins and lintels. The slate roof has tall gable stacks with dripstones and capping, rendered in pebbledash. The main front (east) elevation faces the yard and features symmetrically arranged openings. A gabled porch shelters a boarded door with an overlight, and there are casement windows in the side walls, flanked by two-light timber casement windows with slate sills. Hipped gabled dormers light the attic storey. A single doorway and a two-light window of 16 panes are at the rear, with a smaller first-floor casement window of two panes offset to the right.
The storeyed wing is located at the rear (southwest) corner of the house, with irregularly spaced modern timber casements. A single-storey wing, likely a later addition, is at the rear (northwest) corner, featuring a single window in the west wall. A boarded door sits under a single-pitched roof entry to the east of this wing.
To the right (north) end of the house is an agricultural range, slightly set back, consisting of an in-line structure. It includes a boarded door accessed by a flight of three stone steps, and a four-paned window under the eaves. An advanced wing to the north is a cartshed with a wide doorway to the north and a blocked first-floor window to the left. The range is built against a slope, resulting in an additional lower storey at the rear, forming a three-storey, two-window range. This rear section features a stable door to the left and a four-paned window to the right, with a similar first-floor window above. Loft openings are located to the far right, one retaining a boarded door. To the left of the doorway, the range advances under a catslide roof, with a stable door in the south wall, a first-floor window offset to the right, and a single ground floor window in the west wall.
The interior ground plan originally followed a cross passage layout, although the original partitions have been removed and the hallway now contains a staircase to the rear. Evidence of the building’s past use as a public house remains, including a cellar and a rear ‘servery’. The house retains inglenook fireplaces at each end, and a boarded plank partition in the central hallway. Victorian cast iron fireplaces are present in the first-floor bedrooms, and upper cruck trusses are visible in the attic rooms. The farm range contains unusual diamond section stone beams.
