So I’m up to the lintel height at the back of the building now and I have fitted the first two lintels. One over the patio doors and one over the kitchen window.

They’re not as easy to fit as I thought, keeping the blocks level on the lintel is actually pretty tricky as they seem to have a tendency to tilt outwards, I took it slow and steady and used support to hold the blocks plumb.

I know I wanted the building to be solid but I’m not sure if I made the right block choice with these 7n dense concrete ones, they are a killer to lift and lay!
