Turnastone Court Northern Barn

Grade II listed

 

 

 

Timber-framed barn of mid-late 17th century date orientated roughly east-west. The east side of the barn was possibly destroyed by fire and has been replaced by a brick cow house. The surviving barn has two bays and the frames are three panelled high and built on coursed rubble walls. Some of the panels have an original in-fill of split oak wattle but most are covered by planks or weatherboards. The floor of the threshing bay is of stone flags while the bays to the west are mixed pebble and earth. The roof of the building is of asbestos.

Detail of truss construction (16th-17th century). The trusses have a similar construction with  struts supporting the tie-beam attached to the posts just below the top jowled head. The purlins have been trenched into the principle rafters.

 

The south frame is missing two knee braces in the bay east of the west gable end. Empty tenor joints can be seen in the sill beam and the post of the truss. The knee brace was probably taken out, along with a rail, for the insertion of door.

The north frame has a post missing. The second post from the west gable end was cut away for the insertion of a window.

Corner post of the south frame and the west end gable. Split oak planks can be seen on the exterior of the west gable while original split oak wattle can be seen on the south frame.

The original west gable end was fully framed and stave holes at the top of the rails and groves at the bottom suggest a split oak in-fill. The frame is now weather boarded on the outside. The north-south coursed rubble wall and the sill that rest on it have been cut, to the south of the frame, for a small door. This door was probably inserted for access after the construction of the first additional bay (A) to the east.

Detail of the lap dovetail construction for the south frame and west gable end.

The tie-beam, post and wall plate would have been constructed with the tie-beam lap dovetail assembly. This has been a constant feature of traditional carpentry in England. The purlins have been trenched into the principle rafters.

Struts from the post to the tie-beams are to the east and west. The brick wall of the threshing bay can be seen to the right of the plate. An empty mortice joint can seen on the north-west post of the threshing bay. This corresponds with a similar empty joint on the south-west post.

Sketch drawing of the outside of the south frame showing visible carpenters marks that start from the west gable end of the barn (building 4).

The wall plate and rails are marked. Bay A (building 5) is a later edition and has roman numeral carpenter marks that run from east to west. The yellow truss is later again, probably inserted as a repair. It was inserted before the fire.
