Ranges to rear of the Porth Hotel

The Ranges to the rear of the Porth Hotel is a hotel building featuring stucco with slate roofs, dating from the 19th century. The two-storey front consists of three distinct buildings: two are finished in matching stucco, while the third, which was formerly an assembly room and coach-house, is roughcast. The first two ranges have four windows each, with rusticated, unpainted stucco ground floors and similar rusticated surrounds to the upper windows, set against painted roughcast. The right range features 12-pane sash windows and a door in the second bay, with a timber corniced doorcase supported by part-fluted pilasters. An overlight displays the word 'Porth' in gilded letters. The central range is slightly taller and has roughcast end stacks, 4-pane sash windows, and a door in the right bay, along with a broad doorcase with console brackets, a 4-panel door, sidelights, and overlights. A disk marked 'CTC' is affixed to the upper wall, indicating this may be the earliest part of the building.

The service range has seven windows and is finished in painted roughcast, with 12-pane sashes in the assembly room and one above the loading door in the fifth bay. The ground floor features four altered former coach entries that have been glazed, as well as a door and a window. Beyond this is a lower two-storey, two-window range with a hipped roof. The rear of the service wing includes a three-storey, six-window rubble stone range with a partially blocked large carriage arch and alterations to the ground floor. Extending from the angle is a tall three-storey, five-window rubble stone range, which may have been a former warehouse or mill, featuring stone window heads and 20th-century 12-pane windows on the upper floors, along with a ground floor door and various blocked openings.

The rear of the central block is three-storey with a large gable on the left side, while the southern end block has a three-storey, three-window rear wing facing the old Vicarage. It is suggested that the central block may be the 'new hotel' built on the site of the Porth Inn, which was noted for its imposing facade in a report by the Carmarthen Journal in 1863, with the remaining structures added later. The scale of the range behind the service wing indicates it may have been a former woollen mill.
