Ty Mawr (Great House)

Ty Mawr (Great House) is an early 19th century house with a double pile plan, meaning it has two main depths of rooms. It has a slated roof with a valley where two roof slopes meet, and its external walls are coated in stucco. Four chimney stacks are visible at the gable ends, rendered in the same material. The front elevation is symmetrical, with three bays, and a central doorway accentuated by a distinctive portico supported by Ionic columns with a flat entablature. A later four-panelled front door replaces the original. The windows are 12-pane sash windows with horns, a characteristic feature of the period. The stair window, centrally positioned, is set slightly lower than the others and features a diamond-patterned leaded light and 19th century coloured glass. The rear elevation has similar 19th century sash windows. A square, Edwardian bay window has been added to the west reception room, while the east reception room has a three-sided bay. A single-story lean-to extension is attached to the west side of the house.

A coach-house and stable block, also from the early 19th century, flank the road to the west of the main house. These are constructed from variously rendered and limewashed rubble stone with slated roofs. The stable block has a gable-mounted chimney stack at its east end.

The house retains a fine interior with a strong early 19th century character. The plan is symmetrical, with front and rear reception rooms flanking a central hallway. The original dog-leg staircase features stick balusters, a closed string, and a scrolled mahogany handrail with a grained finish. A four-panelled door leads to cellars from beneath the staircase, and the hallway floor is finished with Victorian encaustic tiles. Six-panelled doors, within panelled doorcases, are centrally divided by a plaster archway with raised and fielded panels. A separate servant staircase rises from the west side of the hallway, providing access to the first and second floors. The west front room retains original 19th century kitchen fittings, with a glazed rear door leading to a scullery featuring a rectangular fanlight with fine glazing bars. Fire surrounds dating from the mid-19th century are present on the ground floor, along with simple, contemporary cornices and skirtings of various designs. The rear east reception room has a matt black slate fire surround with scrolled corbels and moulded jambs. Exposed large ceiling beams with broad chamfers, reminiscent of 16th century design, are present in the front west and rear west rooms; no stops are exposed. Other rooms have plain plastered ceilings.

The first floor follows a similar plan to the ground floor, although the rear room at the end of the hallway has been subdivided to create two bathrooms. Two rooms on the west side have doorways leading to the servants' staircase. All rooms feature four-panelled doors within panelled doorcases. The first-floor hallway is similarly divided by a large plaster archway. Regency-style fireplaces survive in the front east and rear west rooms, with the remainder being later 19th century. The attic has not been inspected.
