A look inside

The inside of the barn is surprisingly intact. Ground level behind the wall on the left is about 6 ft above (inside) floor level. The eaves are about 10 ft above (external) ground level.

The plaster that has fallen off revealed a bituminous undercoat which has prevented much penetrating damp.

This damp patch in the corner comes from a hole in the roof where a stove pipe used to exit.

Building Control have requested details of a damp course (!) system. Presumably this would be chemical and injected. In a massive rubble wall construction some 2 ft thick, we suspect this is unnecessary, ineffective and expensive - or do you know differently?

The floor is concrete and has a step about 18 in. high in the middle. This is what we would expect for a cow barn and as there is no evidence of damp ingress we are inclined not to disturb it. We would simply install a DPC and insulated, heated floor on top of it.
