Well we made progress today, although I must confess it looks worse not better! The hole in the front got bigger. But that is the beginning of the fix.
We had a productive day, the window is out, some more bricks are down and our new RHS is in. The Engineer now tells me that we need a similar RHS on the other side of the building, but I can live with that. Below is a pix of the current air-conditioned hole in the wall.
The next step is to get the safety cage down, happening next week and the new scaffold up for the brickies to work on. At the same time we will put the last 2 steel columns in upstairs. We can not start on the new RHS until the neighbour has finished installing theirs!
