I have been waiting to see the before and after for so long, it has been worth the wait you have done so much! The whole extension and build looks great, obviously you are still at the finishing stage but the actual amount of work done so far is incredible - lot's of hours working away and it was certainly worth it. I'm pleased you have got so far before winter set's in again, it all looks sealed up nice now so it's just tidying up the internals which is easy whatever the weather.
Love the outdoor kitchen area - I bet that was awesome when it was super hot and really nice lay out too.
It is going to be fun seeing the winter progress as you tidy up an finish off the internals.
