Min-yr-Afon, including railings and gate

Min-yr-Afon is a paired house built in the 19th century, featuring painted stucco and a slate roof with decorative fretwork eaves board and bargeboards. The house has yellow brick end stacks, with the right stack shared. It is three storeys high and has a two-window range with plate-glass sashes. The upper floor includes a stepped triplet of round-headed sashes on the right, with the centre sash being taller and wider, and a narrower pair of round-headed sashes on the left, all under a continuous hoodmould.

On the right side, the first and ground floors have a two-storey canted three-light bay window with a moulded cornice. To the left on the first floor, there is a pair of narrow flat-headed sashes, while on the ground floor, there is a round-headed doorway located centre-left and a wider round-headed through-passage to the left. Access to the house is via four steps leading up to a five-panelled door with a plain fanlight. The hoodmoulds extend as strings on each floor, but do not surround the bay window.

The first floor features balconies with fine later 19th-century cast-iron balustrades that extend on either side of the bay window. The front garden is enclosed by dwarf stone walls with ashlar coping, and features cast-iron railings designed in an intersected oval pattern by Thomas Jones of Priory Foundry, similar to those found before Nos 8 to 9 The Esplanade and Union Street Chapel. The gate incorporates the same motif in two tiers.
