Where to put back door

[katcatkat]

We have a kitchen/diner which has been extended with a small extension at the back (its a bit of a silly extension and we use it as a small seating area). we need to replace the back door and I'm trying to decide where it should go should we put the door at the end of the extension or the side (i don't want to leave it where it is as it impeded the kitchen flow too much).
End means we would have a silly garden space that would be hard to use but it looks much more practical for flow.
