The Grambla is a barn located approximately 325 metres north-north-west of Trewoofe Farmhouse, dating from the early 19th century. It is constructed of granite rubble with granite dressings and features a grouted scantle slate half-hipped roof. The barn has a rectangular plan and includes opposing first floor loading and winnowing doorways on the right side.

The exterior consists of two storeys with unaltered elevations. The north front has a centrally located doorway, a blocked doorway on the left, and a small window on the right. On the first floor, there is a splayed slit ventilator on the left and a blocked loading doorway on the right. The left ventilator is opposite a similar one in the rear wall, and both are splayed on the inside and outside. Inside, the barn has limewashed rubble walls, with a 19th-century first floor and roof structure. Additionally, there is a ruin of a small house, likely from the 18th century, located to the west of the barn.
