Tyddyn Wesleyan Methodist Chapel was originally built in 1804, but later renovated in 1885. It has since been remodelled and is a domestic dwelling. The chapel is in the Vernacular style, built from large rubble stone. The gable entrance is cement-rendered with rusticated quoins and surrounds to the windows and doors. There are two panelled doors with small lights over, flanking two paned sash windows. The side elevations each have three paned sash windows. There is a further extension to the rear of the building which is likely to have been the vestry.
