We have wardrobes either side of the alcove, you can fit a lot in them and they look good. One thing though is that we decided not to make them as deep as a standard wardrobe in order to protrude into the room a bit less which means they aren't practical for hanging clothes.
I would mock that up to see how a 60+cm depth would look in the alcove spaces (or ensure you have hanging space elsewhere).
