Pentre-Isaf

Pentre-Isaf is a farmhouse of significant historical importance, comprising a 15th-century hall range and a 17th-century cross-wing arranged in an L-plan. The complex demonstrates multiple phases of development spanning from the medieval period through to the 19th century, reflecting the evolving needs and circumstances of a working farm in the Marcher region.

The older range runs east-west parallel to the track serving the property. It is constructed of stone with some fragmentary square panelling infilled with brick. This range originally contained an open hall, likely dating to the 15th century. The western gable wall was rebuilt in stone during the 19th century. An outbuilt chimney stack was added, probably at the time when the open hall was ceiled over and an upper floor created, converting it to a two-storey structure.

The 17th-century range is set at right angles to and east of the older range, running back from the road. It is a three-bay stone structure with a slate roof, featuring a large double ashlar stone chimney rising through the ridge above a central chimney stack. The building is two storeys tall with a central east-facing doorway and three-light 19th-century casement windows. The north and east walls have been whitewashed. A later, probably 19th-century, service range was added to the west and rear of this block, built with an end stack.

The interior of the former open hall retains its most distinctive feature: the plank-and-mutin screen at the western (dias) end. This screen is particularly well-crafted, with upright planks that are chamfered and finished with lamb's-tongue stops positioned approximately 0.30 metres above the base, which sits on a stone sill. Evidence remains for the fixing of the high seat of the dias. At the north end of the screen is a chamfered doorway with an ogee-arch to the centre of the doorhead, formed as part of the large timber into which the upright planks are tenoned. The door is original, with six vertical planks shaped to fit the ogee curve; however, the doorway providing access to the room behind has been blocked with planking in the distant past. At the south end of the screen is a possible medieval door head on the west side. A quartered timber ceiling was inserted across the hall when the upper floor was created. An Aga is set in the fireplace in the centre of the north wall.

The room to the hall's west may once have been a solar, though this remains uncertain. It was latterly used as a dairy and retains a bacon or cheese storage rack suspended from the ceiling. This room has been extended northwards, where the square framing of the original hall wall is revealed with unusual decorative vertical patterning to the exterior, apparently intended to resemble pebbles or ropework.

Upstairs, above the position of the dias screen, the timber framing continues as a substantial square-framed partition with tie-and-collar-beam construction featuring pegged angle-braces at either corner. A king-strut and two queen-struts appear to rise to the collar beam, with the lower sections of the principal rafters visible. A collar beam and V-strut are visible above the inserted ceiling. The roof appears to be a 19th-century replacement, though only a partial view is possible. The room above the hall has a crude stone fireplace in the north wall. A doorway through the framed partition leads to a 20th-century bathroom above the western room.

The 17th-century range operates on a lobby-entrance plan. To the right (north) of the lobby are the staircase and 'best parlour', the latter containing a 19th-century iron grate. To the left is a room that was used in the 19th and 20th centuries as a kitchen and living room but would originally have been termed the 'houseplace'. This room contains a Coalbrookdale range (stamped with both "Coalbrookdale" and the supplier's name "E. Thomas & Co. of Oswestry") incorporated into the stack. The former service range to the west of the kitchen contains a stone sink, washing copper, and bake-oven. Access to a 20th-century lavatory in the lobby behind the stack is from this service area. A simple 19th-century staircase rises from the lobby and divides to provide access to the men's room (for living-in farm labourers) over the service range, with additional access via a ladder and trap door from the service room itself, as well as to the family bedrooms off a landing. Two bedrooms occupy this part of the house, the main bedroom featuring an 18th-century fireplace with an eared or 'lugged' surround.

The name Pentre-Isaf translates as 'Lower Homestead', distinguishing it from the nearby Pentre Uchaf or 'Upper Homestead'. No specific historical documentation is known for the building. Such farm buildings were typically constructed by the owner-occupier or tenant, the latter generally requiring the acquiescence of the landlord.

The farmhouse is listed as an important example of Marcher vernacular architecture, demonstrating multiple discrete phases spanning the 15th, 17th, and 19th centuries, which collectively reflect changing lifestyles and agricultural practices. The survival of elements from its 15th-century open hall, particularly the dias-end screen, is of particular significance. The retention of accompanying vernacular farm buildings, some of which are independently listed, further enhances its value as an important component of the local agricultural and cultural landscape.
