Do you need all the bedrooms as you will have to sacrifice part of one or maybe two? To try and create balance I would place a bathroom between the two right side bedrooms on your floorplan. This will mean relocating all or part of the wardrobes but there is no other solution.

Most likely you will sandwich an additional bathroom to one side between two bedrooms. Your decision on location will depend on where the drains are. So consider where the downstairs WC is. And consider where the drains are- they are most likely under the driveway and drain covers help you see where they are.
