Description

Bwlch-y-fedwen is a large village farmhouse dating back to the 17th century, featuring two storeys and a four-bay entrance front facing east over the current driveway. The building has a two-storeyed rear wing with a stepped-down roofline, indicating two phases of construction. It is finished in pebbledash with a slate roof that has deeply overhung eaves, along with gable end stacks and axial and end-wall stacks on the rear wing. The entrance is located in the second bay from the left and consists of a four-panelled door with a decorative overlight. The ground floor has 16-pane sash windows, while the first floor features 12-pane sash windows. The gable end facing the street includes one blind opening on the upper floor. The rear range has a blocked doorway to the left and a tripartite 8-pane sash window beyond it, with two 12-pane sashes on the first floor. A lower continuation of this range has a blind wall facing the street.

The rear wing is the core of a sub-medieval house, with one bay still intact. This area is divided by a substantial chamfered cross beam that is dated 1664 and supports broad joists. There is a similar beam against the fireplace wall, and the chimney breast features a heavy stop-chamfered bressumer. The position of a former doorway is marked by an alcove away from the stack, aligned with a surviving doorway that has an 18th-century two-panelled door in the original rear wall, suggesting that this room served as the hall of a sub-medieval house, of which no other fabric is visible. The interior of the main range shows details consistent with a rebuilding around 1820, including a simple spindle staircase and an oddly asymmetrical interior division that comprises one very large room and one small room flanking the stair hall. The details in the continuation of the rear range beyond the stack indicate that this too is a later addition.
