double the lenght quarter the load

4×4 x 2m 4 tonnes, not in my back room

Yes, but unless you have a cast iron ceiling, Robin, the load per post wouldn't be a tenth of that.

It's not the ceiling that takes the holding up, its the walls and roof…

Our first house was a council house where someone has removed the wall from between the kitchen and dining room. By the time we sold it there was a 1" gap along the top of the bathroom wall as the ceiling sagged. It was not a brick wall, but I do wonder if the guy who did it would have done the same even if it was!

My Dad did take a ground floor brick wall out of a house. It's still up now with no problems – he used steel props with the load spread by a scaffold plan on either side of the wall and installed an RSJ across the brick pillars at each end. nearly forty years on it's still holding up!

WOW, sounds ready to collapse. Get acros in there straight away. Then you'll have to take the load from the roof, maybe 2 tonnnes (beware roofs flap around in a wind) and then demolish the bathroom wall, get an rsj in quick and start rebuilding. That'll keep you busy at the wrong time of the year

Once a wall has sagged like that you can never jack it back up into place, unless you are a cowboy

The Council didn't seem to be worried about it, nor did the surveyor when we sold the house… I was glad to move on though!
