Blaen Baglan

Blaen Baglan is a 2-storey house with an L-shaped plan, comprising a long main range with a wing behind, a porch at the L end of the L, a lower projection against the L gable end, and a single-storey projection set in the angle between the rear of the main range and the rear wing. The walls are roughcast. The roof is slate, although mostly missing from the rear slope of the main range and missing entirely from the rear wing, which has partially collapsed. The main range has 19th-century stone end stacks and a ridge stack right of centre, while the rear wing retains a single ridge stack.

The front elevation is 4-window with segmental heads, now boarded up, though traces of former sashes and brick dressings remain visible. The windows, inserted in the 19th century, are grouped in pairs corresponding to the internal division of hall and parlour. The 2-storey porch plus attic has a Tudor arched doorway under a hood, surmounted by a blank frame probably intended for a coat of arms. The upper storey contains an inserted segmental-headed window with brick surround. The attic has a blocked flat-headed Tudor window in a moulded surround with hood mould, formerly of 2 lights. The right side wall of the porch has a sash window at ground-floor level.

In the right gable end of the main range is a blocked 2-light mullioned first-floor window with 4-centred heads and hood mould, set at a lower level than other openings and probably belonging to William ap Jenkin's mid-16th-century house. The gable line of this original house is visible below the present gable, which was heightened around 1600. On the right side of this later gable is a small blocked 19th-century attic window. Behind the main range is a single-storey lean-to, added in the 19th century to create a passage between the kitchen and parlour. The upper storey has a doorway on the left side reached by external steps. The rear wing is obscured by vegetation.

To the left of the porch, the lower gabled projection is a single bay with blocked, probably originally sash, windows and a stone end gable stack. Behind this projection, the kitchen has a 19th-century dairy lean-to, above which is a small blocked stair light to the main range.

The interior, inaccessible at inspection but recorded by the Royal Commission on the Ancient Monuments of Wales, reveals the original plan form comprising a hall with parlour in the main range and kitchen with lean-to 19th-century dairy in the rear wing. Many original doorways are blocked and were replaced by new doorways inserted in the 19th century, at which time partitions were introduced to subdivide existing rooms and the hall screen was removed. The hall has cross beams with broad chamfered stops and a fireplace in the rear lateral wall with details altered in the 19th century. The parlour fireplace is blocked but retains original jambs. The kitchen has broad chamfered beams similar to the hall. The upper storey retains the same original partitions as the lower storey but was subdivided into smaller rooms in the 19th century. The room above the parlour was adapted as a granary with external steps at the rear of the house. The rooms above the hall and kitchen have broad chamfered beams with filleted stops. Attic rooms are open to the roof, the attic in the rear wing having an external doorway in the gable end. The roof trusses of the main range and rear wing have curved-foot principals and lap-jointed collars. The purlins are repositioned, indicating roof replacement and explaining the 19th-century stacks and absence of attic windows.
