Planning ahead for a kitchen central island, with in an ideal world extracting either into the disused chimney flue, or to the side wall.
Of course, the joists go the wrong way for that.
They are relatively large however - 8" at 12-14" centres, for a ~3m span. The whole ceiling will be down for renovation. One thought is that flat ducting through the middle of the joists might work, with some suitable bracing (maybe steel plates bolted through).
An alternative thought is to abandon in favour of a recirculating unvented fan like our old house (aka a 'fat accelerator')..
thoughts?
