This is basically ICF inside out, insulation core surrounded by steel mesh onto which you blast concrete to build walls, floors. I wonder whether it has been done in the UK, how adaptable it is, how it compares to ICF, anything, really.

    I don’t know of any business offering this is the UK. The European preference is to go for pre-fabricated structures, both in timber and concrete, rather than on site systems, so the tendency is for building solutions to be factory-built and transported to site and craned in. Spray-applied concrete is used much more widely in the US and the Middle East.
