Greenbank House, Greenbank, Yell

Greenbank House in Yell is an early 19th century, two-storey and attic, three-bay former merchant's house, with later 19th and early 20th century additions. It features a single-storey L-plan shop attached to the north gable and clasping the northwest corner, along with a later 19th century single-storey, two-bay outbuilding next to the northwest. The walls are made of harled and harl-pointed rubble.

The principal elevation faces east and is symmetrical, with a central four-panel entrance door topped by a plate glass fanlight, flanked by windows in the adjacent bays. The first floor has regular fenestration. The south gable is blank and has a modern lean-to greenhouse. The west (rear) elevation includes a single-storey lean-to wing at the center, another lean-to wing that advances in the bay to the right, and the shop wing obscuring the ground floor in the right bay, with a single window on the first floor in the left bay. The north gable is also blank, with the shop wing advanced at ground level, featuring an entrance elevation to the east that is centered by a shop window with a door to the outer left.

The house has 12-pane timber sash and case windows, while the shop has plate glass fixed lights. The roof is covered in purple-grey slate with sandstone ashlar skew-copes on the house, and harled gablehead stacks with stone copes and circular cans. The shop has a shallow-pitched roof clad in corrugated sheet, with a tall, stepped, single-flue gablehead stack and a circular can.

The outbuilding is a low-gabled, harl-pointed rubble structure with a rectangular plan, featuring a principal elevation to the east that includes a small 9-pane fixed light in the left bay and a vertically-boarded timber door to the left of a matching window grouped in the right bay. It has a shallow-pitched tarred felt roof with concrete skew-copes and a rendered single-flue ridge stack with a circular can.

Surrounding the property are drystone walls that enclose a rectangular garden to the east front, with a lower east wall that has been built up with concrete blocks, and drum corner piers topped with domical rubble caps. Matching piers are found in the drystone walls enclosing the rear garden. There are also a series of drystone walls enclosing a large rectangular field to the east and two smaller fields to the west.
