Apologies for not keeping this updated at all, I've been meaning to do it for ages!
Its been a bit hectic with travelling across europe multiple times since the last update and also moving house to a different country!
Anyhow, pictures from where I left off!
the beams are simply ran lengthwise and notched into the walls.
Smashed it to bits with a sledge hammer, nothing more than a few cm of concrete resting on soil, along with gravel in other places.
I quickly made the electricity in the garage work (3Ph) so they would have a 3ph supply for the pump to do the flooring screed.
Then, I left for 3 weeks back to the UK and let them get on with it!
