Tre'rddol Independent Chapel is dated 1889 on the entrance doorway. The walls are faced with red brick and the roof slated with a red-tile ridge. The chapel has a gable-entry plan and is Sub-Classical in style, with round-headed ashlar heads to single-light flanking windows. The central entry has an ashlar-framed wheel window over. There are red brick buttresses with offsets and the windows have 3-centred heads in the 3-bay right-hand return. By 2003 Tre'rddol had been converted for residential use.
