Thank you everyone for your comments. We live outside Christchurch, and the house was badly damaged in the quakes here. The post-quake rebuild process could safely be described as slightly chaotic, and the house company I am using are located some distance away (like on the North Island), which is why discussion with the architect has been - em - less than optimal. The architect threw something at me to get me out of my comfort zone I think and this is what's freaking me out! I think the windows on the east side are to come (no reason for them not being there), and probably a skylight in the kitchen roof. The section of land is narrow and steep, (this is a historic port town and with access from the south (where the view is); there is no parking other than on the street (south). Patricia - the laundry doesn't sit right with me either! Looks a bit like it's been glued on the side of the hosue. And it is too small as it is to store coats, shoes etc. This is the access to the back garden - thus the door (also means muddy boots can be dumped when we come in!). Entering a house through a living room is very common over here, especially where space is at a premium (small section, small house footprint).

If you are seeking a truly open feel to the floor plan you have shared, then using one material in the mail living area is the best approach to making this space feel truly open. Using a variety of materials on flooring chops up the space and decreases the visual footprint. I would suggest using wood, tile, or if you are on a tight budget laminated flooring for the living/dining/kitchen. Then use carpet in the more intimate spaces; bedrooms and possibly hallway. Save the tile for the bathrooms.

Maybe look beyond the footprint of existing bathroom. We renovated a bathroom where we were able to have a seperate large shower and keep the bath by incorporating a built in cupboard in a bedroom room adjacent to the bathroom. New Free standing storage in that room has resolved any issue with the loss of the built in.

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 .
