Maes-y-Groes Bella

Maes-y-Groes Bella is an L-shaped building constructed from uncoursed rubble, featuring two storeys with an attic. The roof is covered with renewed slate. The front elevation has two 3-light mullioned windows on each floor, which have renewed sandstone dressings. On the left side, there is a large rubble gable chimney, while on the right, a rubble corner stack rises to the full height of the building, heating a first-floor room. Both gables have upstanding verges and copings. The right gable-end elevation has a cellar due to the land falling to the south, which is now accessed through a wooden door rather than from inside the house. There is a single 3-light mullioned window with sandstone dressings on both the ground and first floors, added in the 20th century, along with a 20th-century attic window. To the east, there is a two-storey rubble extension with a slate roof and 20th-century windows. The left gable end features the original door that backs onto the chimney, with a 20th-century window on the first floor.

Inside, the hall has a deep fireplace with a bressummer above, supported by an axial beam. This beam is further supported at one end by a flat bracket against a post and panel partition that separates the hall from the parlour. The parlour contains a 20th-century fireplace in its original position, with an axial beam extending from the centre of the window. The staircase is a 20th-century addition and is not in its original location. The eastern extension has a large rubble stack that dates back to the 18th-century remodelling of the house when this area was used for services. At the first-floor level, there is a late 16th-century or early 17th-century open arched braced truss with cusped struts. The room above the parlour features a timber-framed partition, with the upper part converted in the 20th century into an attic bedroom accessible by a step ladder.
