Description

Blue Hill Manor is a house from the early 19th century that incorporates earlier walls, with the southern part added in the later 19th century. It is built of brown brick, featuring 17th-century red brick in English bond at the rear. The house has a low-pitched hipped slate roof with overhanging eaves. It is designed with a two-storey double-pile plan and has two chimneys on the mid wall. The west-facing front has three symmetrical windows and a two-window wide southern extension. Notable architectural features include a rendered plinth, a stucco floor band, and single- and paired-brackets supporting the panelled eaves soffit. The recessed sash windows have 8/8 panes. The porch, located centrally on the older part, has an arched fanlight that rises into an open pediment supported by Doric three-quarter columns. The fanlight is decorated with lobes over a double circle with paterae. Inside the porch, there are double doors with a similar arched fanlight above. At the rear, there are five sash windows with 6/6 panes and a round-headed radial fanlight above a half-glazed rear door. The house was formerly known as Moodershill Farmhouse.
