Vent hole for bathroom Extractor

[MorphDoc]

Hi

I have two extractor fans in the bathroom which the ducting that goes into my attic and towards a fascia (but not actually through the fascia, just the space) This is the photo

Now naturally I am worried that all that moist air from the bathroom is finding its way back to my attic. I believe this is not the best. So I want to drill a hole in the wall.

Red is there the support beam is located. the green is where the vent would go (somewhere around). Is this structurally safe?

Yes fine

Perfectly safe. Use a core drill.

Use a core drill.

Or failing that stitch drill the 'ole from outside
