Good point - we have a conservatory that the wife will open the window in the kitchen into (still have the outside wall) and the entire place steams up with condensation. We have the dehumidifier tablet devices to combat that.
One option is to change the layout so that the we switch so there's a kitchen and a larger living space. Extension with skylights is sort of what we're looking at - not a complete glass style orangery for the reason of minimising the 59degC in summer and have some insulation properties in winter. I'd also hope the extension style also facilitates some air flow around too by extending the heating into it - either way I will be fitting a big (over spec'd flow rate) kitchen extractor fan.
Sort of this style..

If we get this built one thing I may ask for is a little ledge up in the skylights, so we can put dehumidifier tablet things up, so regardless of the situation the warm moist air trapped there will be dried out.
