Mud & Stud construction was common in Lincolnshire from the fourteenth to the nineteenth century. A timber frame would be built on a stone or brick plinth similar to post and truss construction. Studding of split timber laths was nailed vertically to the horizontal rails. This would then be in-filled with clay mixed with barley straw. This was forced between the studs with a two pronged fork so that the wall could be smoothed off both inside and outside.
The outer face would be coated with a layer of finer clay mixed with a waterproofing agent or lime-washed after it was dry. The interior would be limewashed or left untreated in a barn. The roof would usually be thatched with a large overhang to protect the walls from rain.
A much repaired barn in Tumby near Coningsby, Lincolnshire. Corrugated iron has replaced thatch and the walls are patched with brick, but much of the original structure still survives. The studs are visible internally, where the mud has crumbled.
