What use is a weekend? Why, for stepping back and reviewing progress between working weeks. :-)
Anyhow, this weekend I decided to photograph progress in room RA13 (as labelled in the 2007 attic floor plans). As you can see in the mild panorama below, the flooring is almost exactly half-way across the room.
The photograph below shows one of the beams that was removed. You can see on the right hand end that there has been so much dry rot that virtually nothing remains.
