22 Merthyr Road

22 Merthyr Road is a two-storey terrace of 10 cottages that open directly onto the pavement. The cottages are constructed of narrow coursed rubble with stone voussoirs around the door and window openings, and regular dressed stone quoins. The sides are rendered, and the roof is covered with Welsh slate, featuring narrow red brick ridge corniced stacks, each with three pots.

With the exception of number 14, which is the centre left unit, the front elevations of the cottages each have a single window range and a door, with a ground floor layout consisting of two rooms arranged one behind the other. Number 14 has a three-window range and a central door, with a central staircase layout. The original small-pane sash windows have mostly been replaced with two-light casements on the first floor and transomed casements on the ground floor, some of which have rendered surrounds or slightly cambered heads; the doors have also been replaced. The cottages are set behind a low masonry revetment that slopes down to the right.

Originally, staircases rose beside the front room fireplace in most units (except for the central staircase in number 14), with some staircases still retained. There are some stone flagged floors and slabs from former pantries, and the ground floor ceiling joists are of thin scantling, with some exposed.
