Horeb Calvinistic Methodist Chapel was first built in 1866-7, and later renewed in 1924, with a schoolroom was added in 1853. It is in the later Vernacular style, with a roughcast exterior with rusticated quoins. The chapel is entered via a three-bay lean-to porch adjoining the gable elevation, with a double panelled door set into the projecting central bay. The side bays each have a single paned sash window. In the apex of the gable is a datestone. The side elevations each have three tall paned sash windows. The pitched roof is of Welsh slate.
