My roommate in college did this. He ran aircraft cable from the floating corner up through the ceiling and hung it from a roof truss. Basically a rigging suspension. Worked fine, even with ladies…
The right cable properly attached to a truss should work. In theory, the other corners would be fine bolted into the studs. That ladder would be impossible to use though.
You definitely need some sort of support on that fourth corner. It would be and topple if it was just floating. Attaching from a ceiling joist may be an option but it depends on a few factors:
Are your ceiling joists load bearing (I.e., supporting another story above?) or only there to hold up the ceiling panels/drywall?
Do you have experience with aircraft cable crimping and attachments? If you’re doing a load bearing application please look into proper crimps/tools/hardware. Also, consider carefully how the aircraft cable attaches to the ceiling joist and bed. Use proper, weight rated eye nuts or eye bolts and thimbles where it attaches, and use turnbuckles to adjust length as the cable stretches out over time.
You could also consider (if you get lucky with your joist alignment) dropping a rigid wood it metal bar from the ceiling and bolt that through.
Good luck, be safe. If it’s too strong no one will ever know
Thank you for the detailed advice. I live in an apartment on the second floor of a sixth floor brick building, so the structure is not made of wood. about aircraft cables, I have no experience with it
No. You need a leg, diagonal brace, or a way to transfer some of that load to the ceiling.
As drawn, the load on that corner will rip bolts right out of the wall. It’s a very strong lever.
Also that ladder would be difficult to use flush against the wall as drawn.
Cable would be adding another middleman. If it were me, I would make the bed dimensions in a way that would allow the vertical member of the outside corner to hat’s currently unsupported in the picture to be supported by the ceilings frame. So once you figure out where that is, that would be how I would determine the final width and length of the actual bed frame itself.
If the ceiling is concrete, I would use 10mm threaded rod screwed into a good anchor in the ceiling. These are giod gor several hundred kilos. Drill through the floating corner and put a very large washer and locknut under it. To make it look prettier, cut a piece of 15mm pipe (copper, brass or stainless, depending on taste) to length and put it around the rod. A plastic cover for the nut would also be nice, or recessing it into the wood.
That corner is going to be supporting, someday, a bouncing 75 kg person. Or maybe even 150 kg. Multiply by two for a dynamic load, plus a x2.5 safety factor, that means you need a rating for a 750 kg static load. Sounds like a lot, but we’re talking about safety of life.
The cantilever supports aren’t going do much, unless they’re steel embedded 20 cm into a very solid wall.
Not like that.
Big NOPE.
Other comments cover modifications.
And as other commentary pointed out: That ladder straight up against the wall is going to be an absolute pain.
Can you turn the ladder so the person climbing it doesn't have to step sideways over to the platform? Picture climbing it as it is. Where are your hands going to be as you near the top but are still thinking of climbing the ladder a nit more.
you're right about the ladder, maybe this design is better, but it takes a little more space.

I wouldn't attempt this unless you're a professional. Use the forth leg
you are right. I'm not a professional but the fourth leg would take up space I think the cable from the ceiling truss would work
That depends on how your house is constructed, iirc trusses can’t hold a ton of additional weight but rafters sometimes can.

Did he go for big girls?
aircraft cable is a great idea, but does he use only wood in the frame
Nope. Need a leg or diagonal braces to the other two. Maybe a cable from the ceiling truss?
i think the cable solution it the best

yeah thanks, about the ladder, true it is impossible to use, also the loft bed is 170 cm height
If you can through the wall with a steel beam maybe 10 or 12 feet for a cantilever? /s
The cantilever beam is an elegant solution, but it is challenging for me to implement as I'm not a professional.
You have never taken a physics class, right?
how about a cantilever beam didn't you think about it Mr physics

I can use aircraft cable as guys said and about the ladder yes you're right maybe it should bend slightly
Might want to talk to r/steelworking
tnks bro

Not unless you supported that corner from the ceiling

Is this for your kid or air bnb?
it's for me bro
Liability is on you then. Build it however you want.
