Walled Garden, Tangwick Haa

Tangwick Haa is an 18th-century, two-storey building with a rectangular plan and a four-bay layout, featuring a now-ruinous two-storey, three-bay addition on the east gable. The main structure has harled walls supported by drystone buttresses, while the addition has harl-pointed rubble walls.

On the south (principal) elevation, there is a regular arrangement of windows in the outer left bay. A buttress divides this from the left-of-centre bay, which has a vertically-boarded timber door on the right and a narrow window on the left, with the first floor left blank. Another buttress divides the central bays, with the right-of-centre bay containing a small square window at ground level and a window above. The outer right bay is blank at ground level but has a window above.

The addition extends three bays to the south, though it is ruinous at the wallhead. The central bay is blank, while the left bay has windows on both the ground and first floors, and the right bay features a door at ground level with a window above.

On the north (rear) elevation, there is a narrow window centered at ground level, with flanking windows on the first floor. The outer right bay is blank, and the outer left bay has regular fenestration. The addition extends three bays to the north, with a door centered at ground level, a first-floor window offset to the left, and a blank bay to the outer left, while the right bay has regular fenestration.

The west gable consists of two bays with regular fenestration. The building mainly features 12-pane timber sash and case windows, along with smaller windows that have multi-pane fixed lights. The roof is stone slated with harled skew copes, and there are large, squat apex stacks on the principal gables topped with concrete copes and tapered red cans.

Inside, there is a modern museum interior. Surrounding the building is a thick red rubble wall that encloses a rectangular garden to the south, with gateways centered in the north and south walls, the latter being rubble-infilled.
