it's all mapped out

The floor has been gridded into numbered 1m squares and levels (mm) required to be filled are marked at each junction and a plan drawn up of the whole room.

Shaded areas are the deepest, vertical lines are the next deepest. Range of numbers in each square is the shallowest to deepest depth required to level. X marks the highest points. 

Gary has been to chat through next steps. I'm going to glue down the plastic spacers so we can see the levels needed later on. He is going to order battening to grid off each square so we can work on one at a time, and self levelling to layer on once the grids are in place.

We'll start this work next week when he's back.

Phew, it feels like good progress is being made.
