Description
Hermon Calvinistic Methodist Chapel is a small chapel that has been converted into a house. It is constructed of stone that is covered in scored render, featuring long and short rock-faced quoins and some yellow brick on the sides and rear. The roof is made of Welsh slate and has a yellow brick lateral stack on the left side. The gable end front has renewed bargeboards and overhanging boarded eaves. It features a close-set pair of long pointed-arched windows with intersecting tracery, coloured glass, and painted stone sills. Above the windows is a plaque displaying the name and date of the chapel.
On the ground floor, there are doorways on either side of the windows, each with 6-panelled doors, margin glazed overlights, and shallow swept pedimental heads, which may be modern. Each side and end of the building has a single arched window that spans two storeys. At the rear, there is a single-storey Sunday School extension that includes 6/2 pane sash windows and a doorway with a segmental-arched head. The building is currently undergoing conversion into a dwelling.
