Kitchen Extractor Fan Options

Snow_Phoenix

We currently have a recirculating extractor hood but are struggling with high humidity in the kitchen. We have two windows in there but keeping them open when cooking does not appear to be helping enough, we have had a few items grow mould in the kitchen in the cupboards. We have got a humidity sensor to monitor this and it appears to be in the 60's most of the time.  

Our cooker is on an internal wall (see floor plan below) but is right next to an external wall that we could extend a venting extractor hood to, though one of the windows runs the length of this section of the wall (see pictures below to give context). Where section of wall where there is the recess there the wall changes from an internal to external wall. Is there anything which we need to consider with the window being below the extract vent outlet and the french doors to the dining room to the right hand side?

The current window will be replaced in the near future so will have a trick vent and will open outwards from the bottom rather than part way up, but we can change where/how the window opens if needs be. The wall along the back has a brick built outbuilding on it so it is not possible to vent out of there, thought this is not recorded in the floor plan. 

Any other suggestions of options we had not considered to address the humidity?

Looks like you have nice high ceilings, and plenty of space above the windows. I don't see any issues running a short length of ducting along the ceiling and then out through the wall. Use rigid smooth ducting rather than the flexi stuff to maximise air flow.

could you not just fit an extractor (ideally humidistat controlled) directly into the area above the window but below the ceiling? If it is strong enough you won't even need a hood.

or, if you are changing the window anyway, then another option might be an in-window extractor fan?

Thank you for the replies, I have only just realised I had some. That is good to know @FreeBear. There is a slopping roof above that section of the kitchen so that would not make any difference to it at all?

@BUFF my understanding with the in window extractor fans are that they are not very powerful so would prefer to go for something which had a bit more. We had been thinking about an extractor above the window as an alternative option as well as an option but was not sure if just having the hood venting out would be the best option.
