Description
Newham House is a small country house dating from the early 19th century, with a possible rear wing from the 18th century. The exterior is roughcast render over rubble, with a dry slate hipped roof and projecting eaves. The house has an L-shaped single-depth plan, incorporating a parlour on the left, a central probable dining room and kitchen/living room with a lower floor level on the right, a central rear stair hall, a rear wing at a right angle behind the kitchen, a coach house to the far right, and a late 19th-century conservatory to the far left.
The symmetrical front façade has three windows and two storeys, with a basement on the right. It features original 16-pane hornless sash windows and original 24-pane hornless sashes. A central large 20th-century bay window with glazing bars fronts a widened opening. The conservatory has five bays with four lights per bay, overlapping panes, and a curved roof to direct water away from the glazing bars. The coach house has two hornless sashes with glazing bars. The rear elevation, a three-window range, has a central round-arched stair window with a fanlight. A late 19th-century conservatory/porch with intersecting round-arched glazing bars is centrally positioned. An original doorcase with a reeded architrave and corner blocks is present in the porch, along with panelled doors. One bay on the right has an original 12-pane sash to the first floor, which is blind to the ground floor. A three-storey wing on the left has an early 19th-century 18-pane horizontal-sliding sash above a tripartite window with a 3:6:3 pane configuration, and a six-pane window over an 8-pane casement. The right-hand return has a 12-pane sash and a blocked window opening. The coach house displays two sashes with glazing bars.
The interior retains early 19th-century partitions, floor structures, and roof structures, as well as panelled doors, including a two-panel door with a later-glazed top panel using thin glazing bars. An open-well staircase has an open string, stick balusters, and a ramped handrail that scrolls over the newel. A possibly late 18th-century wooden chimneypiece is found in an upper attic room, along with an old iron grate. The basement reveals deep floor joists constructed from reused ships’ timbers, secured with treenails.
