Tir Glan Cennen

Tir Glan Cennen is a farmhouse constructed from whitewashed rubble stone, featuring large stone end wall stacks, with the stack on the right being larger. The roof was formerly slated. The building has two storeys and follows a two-unit end entry plan.

The front elevation has two first floor windows located under the eaves, with one positioned near the center and the other to the left of center. On the ground floor, there are two windows; one aligns with the near-center loft window, while the other is to the left. Both ground floor windows have stone voussoirs. The right end wall includes an entrance door set within an attractive hipped early 19th-century stone porch, which is arched on all three sides, although only the entrance arch remains unblocked. The arches are adorned with stone voussoirs. To the right of the porch, there is a lean-to that has been altered and features a low-pitched 20th-century roof.

On the rear wall, there is a first floor casement pair that lights the stair, which is located to the right of center, along with two ground floor windows. The left of center window has a timber lintel, while the square window to the right features stone voussoirs. There is also a blocked window with stone voussoirs at the extreme left. The windows throughout the building are generally small-paned casements. The northern end has a fine external stack that is offset three times on the left and twice on the right, with a blocked window featuring stone voussoirs on the left and a door with a timber lintel on the right.

Internally, the farmhouse has a two-room plan with stairs against the rear wall in the center, although the stairs are mostly collapsed. The roof consists of five bays and lacks slates (as of 1998), featuring 19th or 20th-century pine trusses. The ground floor includes oak beams and remnants of oak joists. There is a large timber lintel over the southern end fireplace, which is partly infilled, and a small fireplace at the northern end, with a blank window to the right. A small fireplace is also present on the first floor above.
