Ventilation problem help please

happyhero

I know this looks like another question I put on this site but it is different and I would appreciate any help.

My sister has just got a studio flat and hasn't got much money so she wants me to move her toilet for her and a couple of other things to give her more room in her really tiny kitchen. She wants me to move a stud wall as well. The problem I now have is ventilation. I have been advised to put an extract in the bathroom but once the new wall is built there will be no outside wall so I will probably have to route some pipework to get it to go outside probably over the kitchen units, and into the top glass pane of her very small window.

She will end up with two of these very narrow windows in the kitchen once converted, with a top opening window ( they are those typical metal windows you see in 1950's flats I think). She is 6 floors up so I dont really want to drill the walls, so I was thinking of making one window fixed so it cant open and running the bathroom extract to that and having the glass cut to take it.

But what about the kitchen does that have to have one?

If I did run one for the kitchen it would be awkward where to route it to. It would be tempting to route it to the same window pane but then two holes in one glass would probably not be that good and I would probably be better fitting a panel that would be stronger to take the two which might only just fit. But then you would have toilet extract and kitchen extract, adjacent, doesn't that go against any regulations?

If it did and there was a minimum distance that may be a problem because we are talking a very small place here.

Can anybody help me with the regs on this and what they think I should do please?

make sure if you change any windows that it doesnt require any planning consent. with regards to ventilation, all kitchens need ventillation, cant you hire a core drill for a day and drill through the wall. it will give the exact size for putting your pipe through the walls. most hire firms have them. Its difficult to know the layout and what your trying to do, but the shortest route is always the best. personally I would hire a core drill for a day to drill your ventillation hole.

Thanks for the info, but what happens with the bit you cut out when you use a core drill? I don't really want debris falling 6 floors, and the windows in this area are really small and deeply recessesed, and only the top one opens so it would be very hard to reach my arm out to do anything.
