Description
Nos. 1 and 2 Castle Hill are two-storey houses built with local rubblestone walls, featuring red brick dressings and a colourwashed finish on the front walls. They have thatched roofs with eyebrow dormers. The layout is single depth with small rear wings, each consisting of two window bays and a central door bay. The houses have casement windows, with two lights above and three lights below; these diamond-paned casements were altered in the late 20th century. There are three brick chimneys with paired diamond-set shafts, likely added around 1855. The original rear walls still exist and have small rectangular window openings, but the rear wings, which have slate roofs, were added in the mid to late 19th century (the rear elevation was not seen during the resurvey). A trellised porch is also present. The interior layout and details were completely changed around 1970.
