North West Pavilion, Lussetter, Mid Yell, Yell

Lussetter is a late 18th century building with an early 19th century wing, originally serving as a manse. It features a two-storey and attic, three-bay symmetrical T-plan design. The exterior has harled walls with painted droved sandstone ashlar margins and projecting cills to the windows.

The northeast elevation is symmetrical, showcasing a single-storey piend-roofed porch in the central bay, with windows in the flanking bays and regular fenestration on the first floor. The northwest elevation has a two-bay gable of the principal range advanced on the left, with the ground floor obscured by a modern lean-to garage. The first floor and attic have windows in the left bay only, while the rear wing is recessed on the right with a window at the first floor above a modern single-storey lean-to in the re-entrant angle.

On the southwest elevation, there is a near-symmetrical, two-bay gable of the rear wing advanced at the centre. A modern glazed single-storey lean-to addition is present at ground level to the left, with a single window at the first floor in the left bay. The rear elevation of the principal range is recessed on both sides and is mostly blank, except for a narrow window at the re-entrant angle on the right.

The southeast elevation features a blank gable of the principal range advanced on the right. The two-bay elevation of the rear wing is recessed on the left, with a door at ground level in the right bay and a window in the left bay, maintaining regular fenestration on the first floor.

The windows are timber sash and case, with four panes on the principal elevation and twelve and eight panes on the rear wing. The roof is covered with grey slate and has droved sandstone ashlar skew-copes. The harled gablehead stacks have stone copes and circular cans.

Flanking the principal elevation are two symmetrically-disposed single-storey gabled outbuildings, which have harl-pointed rubble walls and margined windows. The roofs are grey slate with ball-finialled gableheads on the southeast pavilion, which is partially ruinous as of 1997. The northwest pavilion has corrugated-sheet cladding on the roof and a modern garage door on its gable.

The boundary walls consist of harl-pointed random rubble, which have been substantially heightened by mid-20th century breeze block castellations, forming a roughly square enclosure to the northeast front of the house. There is also a drystone rubble wall enclosing a larger secondary garden adjoining to the northeast, featuring a mid-20th century crenellated structure that may have served as a gatehouse, centring the northeast wall.
