Bit of a gap between posts, apologies.

The process after last time was to pour additional concrete over the footings to bring them up to the right level, as the lowest blocks came out with the demolition. Replacing of pipes that had got a bit crushed with the demo, then block work on the footings, with lintels over the outgoing and incoming pipes (water in, sewage out, but also a pipe to take water and electric out to the future bike shed in the corner).
The insulation has gone down over the whole ground except for the inner supporting wall.

And this weekend the pipes for the underfloor heating were laid over the insulation, ready for the concrete slab pour on Wednesday!
