Thanks all. You would not believe how this move has made me feel.
I'm now in a carpeted office with around 12-15 others who travel frequently, so we're not all in the office at the same time. No aircon issues to speak of, in fact it's cosy and warm. Kettle, toaster and small fridge nearby along with vending machine etc. Oh my gosh and some greenery too!

I'm so busy the days are flying by and I no longer have time to be bored.
Long may it continue!
