mine one that i think is the one is the smaller sized collapsible silver tubing leading to the roof space at the moment.
i was thinking a pvc one through the ceiling and leading to the pantry ceiling adn out, but during construction that wasn't in sight at all, - no provision for this in the ceiling joists either.

Do you have pics of how they did the collapsible silver tubing? And which part of the roof space did it go to??? Above the kitchen is bedrooms?
