Outbuilding, Millbank House

The northwest walled garden at Millbank House is an early 19th-century, two-storey and attic, three-bay traditional house that has undergone later additions and alterations. It is constructed from tooled course yellow sandstone with droved dressings, featuring a base course, projecting cills, and long and short quoins.

The south elevation is symmetrical, showcasing a flat-roofed, glazed timber porch from the late 19th century at the center of the ground floor, which has a panelled timber door to the right return and windows in each flanking bay. The first floor has regular fenestration, with the center bay slightly advanced.

The east elevation is asymmetrical, with a window to the right on the ground floor and an off-centre window to the right on the first floor.

The north elevation features a modern addition that projects at the center and includes three skylights in the attic.

The west elevation was not seen in 1998. The house has replacement two-pane timber sash and case windows, a grey slate roof, coped stone skewed gables, coped sandstone gablehead stacks with octagonal cans, and cast-iron rainwater goods.

The interior was not seen in 1998.

The ancillary structures include a single-storey walled garden with random rubble and brick outbuildings that have irregularly placed boarded timber doors and windows. To the northwest of the house is a later 19th-century red brick walled garden with flat stone coping, alongside a low yellow and red brick wall with decorative ironwork railings at the southeast corner. There are remains of two lean-to greenhouses to the north. A second chamber of the walled garden is located to the northeast of the house, featuring a rubble wall to the east and a brick wall for the remainder, also with irregularly placed boarded timber doors. Polished stone panelled gatepiers with pyramidal caps are situated to the south of the house, along with two-leaf decorative ironwork gates. The boundary walls are made of random rubble with rubble coping.
