Ynys-felen

Ynys-felen is a long, whitewashed building with a four-bay front facing east. It is constructed from rubble, with cob under the eaves and on the right gable. The roof is made of corrugated iron over thatch, featuring wide boarded eaves. There is a large rubble chimney stack on the left gable, while the right stack has been removed, and there is a gable stack on the rear wing. The front has windows with timber lintels and stone sills, including 19th or early 20th century two-light six-pane casements, although the door is missing. The wall thickens to the right of the door, indicating an extension from around 1800 at the parlour end. The left end of the building has partly collapsed, revealing joints of a former cross-passage door. The right end features a six-pane attic window. The blank rear wall is largely made of cob.

There is a large two-storey rear wing that is connected to the main heated room by a small narrow room, although it was formerly separate. The kitchen is built of rubble and cob, with the gable having been largely rebuilt in brick. The south elevation shows remnants of three large buttresses, a four-pane sash window to the left, and a small window to the right with a stone lintel. The north side has central stone steps leading to a boarded loft door, with a ground floor door and window to the left of the steps.

Originally, the front range had a three-unit plan, but most divisions have been removed. A part of a post and panel partition remains in situ, featuring narrow stop-chamfered posts and wide panels. This is a rare early 18th century survival, with only six known examples in Cardiganshire and two in Carmarthenshire. The main room has a wide fireplace with a roughly chamfered bressumer and a modern tiled grate, along with massive roughly chamfered beams. There is a ladder stair leading to the loft, and the roof structure is complete. The older portion of the roof has three pairs of scarfed crucks with high lapped collars, while the added section has just one pair of scarfed crucks. The underthatch consists of pole and wattle, with some wall-posts visible. The southern pair of crucks are partly embedded in the chimney wall, suggesting that the chimney was inserted later; this, along with smoke blackening in the roof, may indicate that there is a core of a cruck-framed medieval house. The sheltered downslope site also shows early foundations. The rear kitchen features a modern grate and rough beams. At the time of inspection in January 1996, the building was in deteriorating condition.
