Tricia's current outdoor project ...

... is trying to get the big pipe through the small hole in the wall. Not sure it is going to work and so we might end up having to go down the macerator route although I am not 100% enthused with the prospect. I konwe who will end up trying to sort it out when it gets jammed.
I ended up using my carpentry skills to create some frames for glass tp put in some of the current wall openings dotted around the buildings. It does seem a shame to heat the house just for it to escape through holes in the wall. Our wood burner has now been alight non-stop for two weeks and certainly has made a difference to Tricia's cheerfulness levels.
