Yes, very nice, thanks.
I have a question, the render on the exterior, which you skipped?, would you have done it if the building had been lower?
One way around the gable ends is to insulate the ceiling/attic floor and have the roof not heated. The gable ends can be frames with studs and sided, a wall build over the infilled section.
Is the reason for not infilling against a permanent wall surface due to the drying ability?
