The earliest parts of Trelydan Hall date from the 16th century, and are timber framed, the 18th and 19th century additions are brick, later painted in imitation of framing. The building was originally approached from the northwest, and this elevation was therefore previously the entrance front: it comprises the main range and cross wing plan attained in the 17th century, with the later wings to either side. The original 16th century gable forms the left- hand wing: it has square panelled framing and a jettied gable. The main range abuts this gable, and has a storeyed porch to the left: this is close-studded, with lozenge decoration to panels in return elevations at first floor level, and chevron decoration in gable end. The richly detailed decorative framing extends to each elevation.
