Underground pillars

In the last day or so, block built mortared pillars have appeared along the fron edge of the cellar.  They are outside the insulation, and look quite permanently built.   I hope to find out what they are for during today.

Elsewhere, the road above where the connection to the waste water will go in has been dug up.  It looks to have been done very neatly, but the digger has been parked on the road overnight, making it not wide enough for cars.  That's not going to please the neighbours.
