It would be best to install a couple of high level air inlet points on your
downstairs floor. Keep them up near to the ceiling height so they don't suck
cold air in at floor level and have your feet freezing in the winter months.

Presumably then a retro fitting of window vents into the other 3
bedrooms and one in the boiler room door will spread the air intake
across all bedrooms reducing the surges in the main bedroom (only vented
one)

I am presuming you can just buy and "cut in" window vents to UPVC window
frames? which would be better than a brickwork/ducting alternative?
