A run it’s a pen, if you put the run towards a wall you will get a larger space. But the crate will have to be the largest dog crate you can find.
A picture from a news side in my language of a flemish giant

Hope your bunny won’t be escaping, I know my holland lop would easily jump over a run like that while my french lop would often move the run, if it’s not anchor to a wall. She knows how to open some doors even though they are closed, the quirks of having a large bunny.
Will your bunny get time outside the cage? and how big will the run be ^^
Myself have a 15 sqm run/pen but that’s outdoor while the cages it’s 3 sq m for my french lop and holland lop they are outdoor bunnies. The run it’s not enough space for my french lop to play in, so I often make sure she gets the chance to run loose in the yard instead.
Just asking because larger breeds need a lot more space than smaller breeds to play around on. For example my netherland dwarf would have no problem playing in the 15 sq m run while my french lop it’s just a few jumps and she’s on the other side. She’s half the size of a flemish giant at 13 pounds.
Myself when I get a flemish giant it will free roaming instead of having a cage. So I’m waiting until I can provide it with that instead.
