Description
Brynhafren is a former pair of back-to-back houses that were part of a longer symmetrical terrace next to Spring Mill. This three-storey building is constructed of red brick with a slate roof, featuring bracket eaves and a blue brick chimney stack. The front of the building has one window for No 1 and two windows for No 2; the second floor has 12-pane sash windows, while the first and ground floors have lintels and keystones, with No 1 having 16-pane windows and No 2 having modern windows. The mid-20th century doors have bracket cornices, and steps lead up to the right of the center, leading to a round-arched entry into a tunnel passage with a four-panel door.
The left gable end is rendered and was rebuilt after the rest of the terrace was demolished sometime between 1963 and 1981, while the right gable end is made of shale. The brick-walled tunnel passage has a door to the left midway along and another door to the right at the end. The rear elevation is made of shale, partly rendered, and features small pane metal frame windows on the second floor, which appears to have been a weaving loft. This loft has a boarded door that is accessed from the high rear garden by an elevated walkway.
