Description
Myrtle House is a terraced house built from dark red brick in Flemish bond, featuring differently coloured brick on the top floor. The building has nogged brick eaves and a slate roof with a brick stack at the left end. It stands three storeys high with cellars and is double-fronted, showcasing a central doorway. The ground and first floors have large 12-pane horned sash windows with cambered brick heads, while the top floor has flat-headed square 6-pane windows, with their heads breaking into the base of the eaves. The central door, which has a stone step and a boot-scraper, is made up of four fielded panels and topped with three glass panels, all framed in a moulded timber architrave with a flat hood supported by shaped brackets. There is a basement vent to the left.
The rear wall is constructed of rubble stone and features an iron leaded casement pair on the top floor to the left, a cambered-headed 12-pane sash window below, and a small cambered-headed window at the centre of the first floor. The right side of the house steps out in line with the rear of No 4, with brick quoins on the left, an iron casement pair on the top floor, and a 12-pane window with a cambered head on the first floor.
The interior has not been inspected, but it is said to have beams similar to those in No 4, as well as a kitchen fireplace on the south side with a boarded curved-headed surround and a spit-rack above. Originally, when it functioned as two separate houses, there were two doors off the hall passageway and two staircases.
