The Mansion House and Attached Wall

The Mansion House and attached wall is a house dating from around 1770, with some early 19th-century alterations. It is constructed of brick with ashlar dressings and has a tiled roof with brick end stacks. The building features a gable facing the front to the left and has a central staircase plan, designed in the Georgian style.

It stands three storeys high and has a symmetrical three-window range. The top cornice and coped gables with kneelers enhance its appearance. The ashlar ground floor includes a wooden frieze and cornice, while the round-headed entrance is framed by a Doric aedicule with an open pediment, featuring a fanlight with radial glazing bars above a six-fielded-panel door. Flanking French windows are supported by fluted pilasters. The upper windows have rusticated wedge lintels, with the first-floor windows being 12-pane sashes and the second-floor windows being 6-pane sashes, all with sills. An enriched cast-iron balcony spans the entire facade.

On the right side, there are two first-floor windows with cast-iron balconies. The rear wing, which is also three storeys high, has a modillioned brick cornice and a re-entrant lean-to porch. The fenestration varies: the ground floor features three segmental-headed windows with wooden frames; the first floor includes a small light, a four-pane horned sash, and an end segmental-headed casement window; the second floor has three three-light casement windows with iron opening casements and leaded glazing, with the end window having small-paned glazing. There is an end stack to the hipped end. A 20th-century entrance and light are located at the rear, with two four-pane sashes on the first floor.

On the left side, there is a tall segmental-headed recess with a first-floor window that has a pegged frame. Inside, the house features an open well stair with an open string, alternate column-on-vase and barleysugar balusters, turned newels, and a ramped handrail. Some window shutters and six-panel doors are present, along with Minton mosaic tiles. The house was originally part of the iron works of Rangeley and Dixon, founded around 1818, which later became Rangeley and Diggles, known for making mileposts for the Trent and Mersey Canal until it closed in 1829.
