The Vicarage, Trellech, dates from the late 18th century, and was built as the Vicarage of the Church of St Nicholas in late Georgian style with a neo-classical door surround. The house is entirely roughcast and has a Welsh slate roof. It is a double fronted single depth house of three storeys with a two storey extension to the right. The central bay projects slightly and has a six panelled door set into a round-headed recess and fanned plasterwork to the tympanum. The front garden has a wall with piers to a simple ironwork gate.
