DD and DS sharing a room?

[MayorMumbum]

For a few reasons we have had to do a rushed house move. We will only be staying here a year.
The issue is the box room is really, really tiny and barely fits a single bed with a chest of drawers. We have an 11yo DD and a 7yo DS. Would it be terrible for them to share a room for one more year until we move somewhere bigger?
Our three year old DD still has a cot bed and barely plays in her room so would be OK in the small room. DS loves his loft bed too which doesn't fit in the box room at all.
DD1 and DS are fine to share as they get on quite well but I'm aware it is becoming an issue now DD is secondary age and starting to develop etc.
We can't give up our bedroom as DH works from home two days a week and needs the privacy to concentrate.
Opinions/ thoughts are welcome as I really need to figure out what to do!

If its just for a year, I'd talk to your dd and ask if she's happy to share with her brother for a year or wants the smallest room so she can have privacy.
If she feels uncomfortable she needs her own room.
And a 7 and 3 year old can share as well as a 7 and 11 year old.

What does DD think? I think I' d be tempted to let the younger 2 share rather than the older 2, but depends a bit on the size of the room they are sharing (is it big enough for them to have their own space, or will they be quite cramped niP.

I'd obviously consultant them all but probably suggest DD (11) has the box room and the 7&3yr olds share.

Consult

DD1 is fine sharing but DD2 and DS sharing wouldn't work. They would never sleep, she would constantly be trying to throw herself off his loft bed and it would generally get a bit Lord of the flies .

I think 11 year old should have the box room. Otherwise divide up larger room with furniture so they have separate spaces.

DD will still be sharing at age 11 (DS will be 5) before we can afford to re-jig the house to allow the kids to have separate bedrooms.

We insist that DS stays downstairs when DD is getting changed and DS isn't allowed on DD's top bunk (so she has space away from him if needed). They should have separate bedrooms by the time DD is in Y7 or worse case Y8 but we'll be mindful of DD getting some privacy without DS in the room.

My DS(10) and DD(7) share a room. They are fine with it. To be honest they only really use it for sleeping and prefer to spend time downstairs to play etc.

As and when this changes we will reassess I guess.

If they're both fine with it I would.

My DD14 and DS11 often share a room when we visit my mum to stay.
They all share a room on holidays. They have also shared a large double bed. Never really been a problem.

It's not for along time.
