With the roofers putting the roof back together, this has given the builders the opportunity to start rebuilding the extension. This had to be re-built as it was a single skin building with a flagstone floor that had been laid directly onto the soil below. There is little that could be done with this part of the building other than to rebuild it as it should have been built in the first place.
We have put in a new concrete floor (and damp proof membrane) and new foundations. From the outside, the extension will look the same as it did before, but with a cavity wall (and insulation). We are even going to put the old coal hole back.
Once the extension has been rebuilt, we will need to get the sandblaster back to lighten up the exterior stone otherwise the extension will not fit the rest of the building.
The first few courses and the keystones going in on the re-built extension.
