The WC today has its Fermacell panels stapled up. It was a bit tricky with the smallness of the room, trying to get full size boards into the doorway and discovering the impossibility of squeezing it in, like a square rod into a round hole! So we had to cut them in half and glue them back together again on the walls! Of course the other complication was the pipes (for the basin and loo) sticking out the wall and sliding the Fermacell panels (after making the holes in the correct places .. hopefully!) and getting them flat on the walls! Actually it went well after all!
The Window has been lined also with Fermacell, ready for the Oak frame to be inserted soon, real soon!
