I would think you would need at least 50cm depth to hang clothes. Is the ikea wardrobe part of the kids/nursery range? I like your idea of moving wardrobe to the 'north' wall. I don't think it would be absolutely necessary to change the door swing provided a rubber stopper is installed to stop the handle hitting the robe.

depending on how much storage you need, i suggest a walk-in wardrobe that would have 4.8m of 60 cm deep hanging and shelf space and a central floor area of 120cm x 120cm. There's a wall to screen the view from the bedroom's doorway and the door can remain as is. One or more 45cm deep chests of drawers or a dressing table could be placed opposite the bed, the walkway between the drawers and the bed would be 85cm deep (standard hall is only 90cm) and being below eye level the chests of drawers would not visually encroach on the space. The walls of the walk in wardrobe need not reach the ceiling unless you want high storage (full height walls would create the need for changes to the ceiling and extra ceiling lighting. A similar effect could be created with two free standing wardrobes facing each other so you could see if the arrangement worked for you before you add the walls...whatever you decide hanging space has to be at least 50cm, preferably 60cms deep or your coat hangers will be hanging crooked and your clothes would be squashed

I love the layouts by Twos Company Reno's & OKLouise. Having the wardrobes there also drowns out any noise coming from the bathroom/toilet room. I'm a great fan of cavity doors, they take up no space whatsoever, and because they need to be fitted inside a wall, and if you do change the layout of the wardrobes, whats a bit more finishing. If I could I would have all cavity doors in my house.

I would remove the current robes and build in a walk in robe near the door and yes the entry door needs to swing the other way.

The current robes would be destroying the balance of the beautiful bay windows. Then you should be able to place the bed on the other three walls.

Alternatively you can do an ensuite 1.35M wide and have the wall facing robe on the other side .6M which would take up 2M of the room. Makes what must have been a living area a master suite.

The previous suggestions are fabulous, so if you have the money, I would go with one of them.

If you haven't the money, then I would do what an earlier reader mentioned and have the bed facing north near the bathroom. You can run a power cord along the floor and you can buy white plastic covers that hide the power cord discreetly on the skirting board. Then place a chair and small table beside it near the bay windows to balance the length of the room and perhaps hide the power point. This is not the best solution as it'll make the bed hard to make and have little room for a bedside table. But it is cheaper. Just an alternative.

Another way to do this cheaply would be to do what Two Company's Renovations suggested but instead of building a wall using your cupboards as the wall and making your own large, bed head to cover the back of both of the cupboards. Just a thought.

Still building the wall or walk in may not be as expensive as you may think. Worth getting a quote.

I have your room dimensions as my master too. Currently the wardrobe is on the north wall BUT it is very narrow - you can hang a t-shirt but anything bulkier like a mens jacket gets stuck - it is not good for clothes and annoying too.

Back in the day, all bedrooms and bathrooms tended to have doors that would not immediately provide a view all the way into the room. Nowadays we put a higher priority on how the room is showcased, and hence, doors are more revealing.
