How to make concrete block shed safe. Is it repairable or a knock down job? Help

My boyfriend had a man build a concrete block shed over 10 years ago. There was tree in the neighbours garden and after it was chopped down massive cracks apparently started appearing in the wall in that corner, so assumed foundations movement ( concrete base to shed). Last year when I moved in I kicked off that it needs looking at. We put spacers to see if there was still movement or if it had stopped. This spring when I popped my head inside the shed to get lawnmower, one of the spacers has actually fallen off and the cracks are huge! The crack in the side wall is both horizontal and vertical - it has created a free standing wall that doesn't seemed joined to the back wall?

Also crack above door is worse, where render fallen off looks it like no lintel was put in and wooden frame of door is all that is supporting the above bricks etc! Eek!

I've since banned us from going inside the shed and warned neighbour to stay away from that corner, but they have a dog.

How best to make it safe so that we can get to our stuff for now, and can be repaired or is it a knock down job? We want to sell and move this year.

Clearly it needs lintel put in above the door and rebuild there. Side wall, if lots of movement still, what are the options to ensure roof supported and no bricks fall on anyone.

Scary photos attached.

Initial thoughts are to buy acrows to support the roof at that end in both corners. What about door so we can still go in and out? Plus the free standing wall?

Been quoted £600 to put acrows up which seems a bit steep!

I’m no expert but I’d say that needs coming down and rebuilding on proper foundations.

Side wall pictures and front of shed picture didn't load. These are them.

@Mottie I was wondering if that might be the case and then just put a cheaper wooden shed up, but of course hoping we can save it with min agro. We want to spend minimum as we'd like to move. It is rammed full of bits Inc storage of his ex's stuff. Will need to make it safe enough to go in a move thing stuff out to somewhere!

Looks like it has a lintel above the door already.

Presuming this is a single skin thick (one block) and it’s built on a concrete base. Is the base cracked to bits in the corner where the tree was removed? Certain soils are more prone to movement and when trees are involved can create problems… like clay based soils, do you know what the tree was?

Think I’d be inclined to bin and start again (as it’s still moving) as mottie had mentioned.

As for acro props, you could buy these off FB marketplace, they are a doddle to use, probably get some for £20 each (ish) and do it yourself.

If it's condemned then just knock it down and dispose of it, otherwise that's what any buyer will have to do or factor in when they buy it (and would you want a new owner nosing around it after they'd bought your house anyway). Don't waste money building a new shed in its place. You seem a bit paranoid, I don't think it would worry me going in there to move my stuff out. Storing stuff for his ex? What's that all about? Leave her crap in there for her to collect, if it collapses whilst she's in there then that's a win win, saving on the demo too.

As above, and don't waste £600 on that crook and his acrows - the roofs not going anywhere and is probably the main element holding the walls together - until someone starts jacking it up.....
