Are you suggesting no inlet ducts to the bedrooms or have I misunderstood?

You have not missed anything. You will have extract in the en suite and plant room. So air will be pulled though the house. You still need to balance flow and extract rates overall.

 

Air will sort of following the red lines and be extracted following the blue. So whole house is covered. Use a couple of coanda nozzles at top of wall by cycle room and the air will travel across dining room before dropping down and being sucked to extract points.
