The present building at Noddfa appears to be the Sunday School built at the rear of a now-demolished chapel. the chapel was accessed via a broad opening in the side of the present structure which is now blocked. The gable-front entrance is of squared rock-faced Pennant Sandstone rubble with side walls of coursed rubble of the same material. The central gothic doorway of the single-storey late-nineteenth-century structure is flanked by gothic windows with simple intersecting glazing-bars, with a plaque over the doorway. The windows on the sides are of simple domestic type.
