We went to check on the new house. The agents had told us the hoardings had been moved and the scaffolding was down. The builders still will not allow us anywhere near the house, but there is a vantage point from which GF can take his long distance photos.
We arrived at the vantage point. Some of the hoardings were indeed down - but not those which obscured the ground floor of our house. From what we could see, the tiled sections of the walls was complete and everything was looking fairly clear.
