Description

No. 1 Tai'r Ysgol, also known as School Cottages, is part of a group of three attached single-storey cottages, with a two-storey central projection for No. 2. Built in a picturesque Gothic style typical of the earlier estate buildings in the village, the cottages feature uncoursed rubblestone with reddish brown brick window heads, dripmoulds, and chimney stacks. The slate roof has hipped ends. The facade is arranged in a 2:3:2 bay pattern, with the central projection having an equal-height gable.

No. 3 retains its original three-light timber mullioned and transomed windows, while the other windows were replaced in the 20th century but still have 19th-century cambered heads. The central boarded door to No. 2 has a two-light window above it. The entrances to Nos. 1 and 3 are located on the returns, accessed through cambered doorways in set-back screen walls with porches behind. There are short ridge stacks with moulded capping and chimney pots on either side of the central projection. Additionally, No. 1 features a large box dormer at the rear. The interior was not inspected during the survey.
