Now, I have no idea whether this would be allowed or not. Is there a
way for me to get something like "approval in principle" before
actually buying the house???

You can apply for planning permission before buying the property. You need
the permission of the current owner

No you don't! I know of a case of someone getting planning permission
for an extension that went onto the neighbours garden, without the
neighbours knowledge. It was cock-up rather than conspiracy in this
case.
