I think they all look pretty nice and very exiting for you. From my experience make sure you have enough seats and space on the island or peninsula and work out who would be sitting there most. I say this as you have cooking and a sink on the island- so with young kids I would be less keen on cooking, and if it’s guests then I wouldn’t really literally to be cleaning my dirty dishes in front of them. Personal choice and maybe just me. Therefore I like the design with the sink at the window but I would loose the high level storage units on the sink wall and leave it more open. Enjoy hope the build is going well.

You have quite a few different options there.
I like the ones where you have low cupboards on the outside wall as well as the full bank of high cupboards. You’ll have plenty of storage then.
But I would lose the high cupboards on that wall and move both the sink and the hob to there, leaving the island clear. The larger picture window is better on that wall than the actual window design.
I’d consider sliding doors in the lounge area then - as large an opening as you can manage.

Both are nice but I personally think a more contemporary design is the first one with the bank of units all the way across. Having said that I don’t like the position of the sink. It is too close to the edge and I sometimes think a hob and sink both in an island create clutter.

If you opt for base units along the window wall as the others have suggested ditch the wall units and perhaps add a couple of shelves instead. Difficult call.

If you lose the wall units on the exterior wall - you could run the full-height units the full length of the wall and still have the length of base units on the right. I agree with Daisy that the more contemporary look is the island with the back wall of units but it leaves you with having to put the sink & job on the island & much less countertop to work on. I always wonder where the kettle goes when I see those types of kitchens.

A quick observation on your plans, if you're planning on a 'true handleless' kitchen as in the elevations, than your plans haven't allowed for the gola handle rails.

I think I would go for the bank and the island as all the comments agree it is very contemporary. I think I would lose the worktop overhang (or reduce it) and the stools on the island. This would make cooking safer as no one would be seated there. You can still see everything going on and supervise from that cooking location. I would move the dining table and chairs/benches closer to the island and have the living area where the dining area is now. You have a large glass door so will still have a view of the garden. There is plenty of room for a single sofa against the back wall behind the dining table and with a garden view if so desired.
