Fill in time
Even with the skies clearing, after a fortnight of needed rain, the renderers now have a significant backlog of other project work that must be dealt with before they can get around to the Terraces. Our project waits in the queue.
In the mean time:
Instructed builder to seal gaps between top of common blockwall and underside of sheet roofing with fire insulating batts to ensure the required fire separation between the Terraces.

Gaps in party wall require
fire-rated fill
Also confirmed detail of the high level window within the steel frame to the rear bedroom - will need to move the window further in for weather protection, which at the same time will provide visually cleaner lines externally.
Electrician will be starting the fitting off of power points and light switch plates shortly. Noted that the TV point in Bedroom 2 clashes with the position of the hydronic radiator panel and will have to be relocated sideways.
We will need to fit high period skirtings with a concealed narrow duct to the east wall of the Lounge and front bedroom, as the hydronic pipework could not be embedded within the concrete slab as was possible in the new rear section.
