What's the crack?

Yesterday morning, while waiting outside the site office for the start of the meeting, I noticed this crack in the front of the original house:


It runs from the ground all the way up to the upstairs front bedroom window, and goes right through the wall. I'm convinced I would have noticed it before if it predated the building work. We're waiting on the final figures from the vibration monitoring done during the foundations, but we don't expect them to show a level high enough to have caused this. So, the project manager will be affixing a device on the crack to monitor it. If it doesn't move it should be straightforward enough to tie the wall back together. I don't want to think about the alternatives.

On a happier note, roof work began in earnest today:


It's a bit hard to see with the scaffolding in the way, but this is the view from the back:


Inside it looks like this:


Just the front section has been fully beamed as of today.

Finally, yesterday's meeting was attended by our new plumber. Once papers are signed and exchanged he will officially be part of the team.
