Whilst stripping a plaster skim & 25mm browning wall under the ceiling eaves, I notice the bricks just beneath the eaves are arranged very differently. The bricks are a vertical soldier course of half bricks, with the frogs facing inwards creating a very thin wall. This is about
15" above the chrysotile roof soffit line, 1949 build.
What I find odd is the soldier course is not fixed by mortar. Instead the same plaster browning as that used underneath the plaster has been used, easily scraped out by a screwdriver, 95% sand in terms of no mechanical resilience.
Was it left to the plasterers to bring the brickwork up to the eaves?
