Trephilip Farmhouse

Trephilip Farmhouse is a 17th-century building originally constructed by Philip Bullen and later passed to the Vaughans of Porth-aml through marriage. It is said to be located on the site of a house that belonged to Marie de Bohun, the queen of Henry IV.

The exterior features 17th-century elements with 18th-century additions and remodelling on the eastern front. The farmhouse is built of colourwashed stone with brick dressings and has an interlocking tiled roof that is hipped at the southern end. It is two storeys high with a three-bay plan, including a cross passage behind the main axial stack. To the left is a hall, and the kitchen is located in what was formerly a service room or cowhouse to the north of the passage, with an additional service room at the rear that likely dates back to the original construction. In the early to mid-19th century, a parlour bay was added to the southern end, featuring two windows facing south. The cross passage was covered by a two-storey gabled porch that was set forward at the same time, which includes a six-panelled door and overlight in a 19th-century doorcase, along with a narrow six-light casement window above. There is a part-glazed door leading to the kitchen and an external gabled porch. The farmhouse has nine-pane sash windows, although the southern end bay features late 19th-century six-pane sashes. A cellar is located under the rear service room. The house is connected to a one-storey and attic farm building at the northern end, which is set at right angles to the house's axis. This building is made of whitewashed rubble with a slate roof and has a door and three openings on the ground floor facing the farmyard.

Inside, the main living hall contains three chamfered cross beams. An early 18th-century staircase with twisted balusters is present. According to Jones (1964), the kitchen may have originally served as the hall with an inner room, while the present hall is believed to be from the 18th century, coinciding with the date of the staircase behind the axial stack, which was remodelled in the early 19th century.

Trephilip Farmhouse is included in the heritage register as a mostly well-preserved farmhouse that illustrates the evolution of accommodation from the 17th to the 19th century.
