How come you don't want to go with the two lounges in the room if it works out okay?

I'd take a totally different route . It looks like there is that narrowish window in the lounge or dining area -- I'd look at whether you could make that into a ranch-slider ( yes , I am in NZ too -- if you say ranch-slider it confuses the Aussies haha ) . You'd need a structural engineer to make sure that wall isn't load bearing , and also electrical cables are able to be moved , but I'd suspect the load bearing bits would be the corners , and you'd be able to 'open up' that wall onto the deck . While it initially may seem counter-intuitive , you could then take out the door and that other taller window -- close it in and add a couple of small windows , or how about doubling down , and seeing if you can 'open up' between what you call the 2 windows above the stove -- have 1 long flat window along there , OR even do another bay window -- that will add more light , but also by taking out the opening door , you will get an extra metre of space , That way , you can do a different kitchen design -- maybe a wall mount oven , or a pantry , a breakfast bar in a different spot -- basically , plan the kitchen and the window placement at the same time . The advantages would be more usable space , more light , an indoor/outdoor flow but through the other room , not the kitchen . But with more glass actually in the kitchen , it will feel lighter and airier , plumbing won't be as much of a hassle , it will look better . The only possible downside would be the wall you put the ranchslider in will need to be kept clear , as you may lose a bit of space there , but the breeze and openness will make up for that IMO .
