Castell Hywel

Castell Hywel is an 18th-century farmhouse that has a core dating back to the 16th or early 17th century and has undergone alterations. The exterior is roughcast with a slate roof and features small 20th-century stacks at the ends. The building is two storeys high with an attic and has a five-window range of 19th-century margin-light sash windows, two of which have been replaced with plastic. The central door is framed with stone voussoirs. There are 20th-century flat-roofed additions at the rear and right end of the house. The roof eaves were raised by approximately 0.5 meters around 1980.

The left end wall is made of whitewashed rubble and has a small raised patch of stonework with corbelling that is of 17th-century or earlier type, which is the base of a first-floor chimney. The design of the house suggests it was rebuilt in the 18th century, but the presence of very large re-used beams indicates that it was originally a substantial earlier house.

Inside, there are very heavy oak beams on the ground floor, including two reused beams and a large end fireplace with a long timber lintel that is cambered over the fireplace opening. The dog-leg stairs leading to the attic feature paired column newels and turned balusters, likely from the 18th century. The first floor has large beams, one of which is reused. The attic retains its original trusses, although the roof has been raised. The pegged oak tie-beam trusses do not have collars, but small bird's-mouth cuts may have been intended for a cross-piece. One of the trusses has the date 1794 scratched into it.
