I think the first layout is fine. You might want to consider moving the door for the storage room of the master bedroom so that it opens into the hall. That way the kids can use it for overflow storage. Also, that hallway is big enough that I think it could hold a large armour, providing more closet space. (There's no need to sleep in the same room as your clothes, so long as they're not too far off.) Also, don't forget that while the drawing shows kids in double beds, this need not be the case, so there will be more room for furniture (dressers or whatever) in their rooms. Finally, that step to bedroom 4 will not be odd at all. I've seen it in other homes. It looks clumsy in the drawing but it isn't. What you'll see when you come up the stairs is a bedroom door on a slight diagonal. It's only an odd jagged step if you walk like a robot, in straight lines along the wall, which is what your eye is doing on the drawing but you won't do in real life.

~$400 including expedited shipping. My GC just had his regular countertop guy do them, which wasn't great.... he had trouble making clean cuts. If I were going to do it again I would have pressed for someone with expertise to cut them. You can see in the image that the facing is not made of the stone peak, because too much was broken during the cutting to make the mitered edge. I'm a little bummed, but mostly pleased with the surface (which is the important part) thus far.

We got the IKEA shelves that are pictured in the butlers pantry photo I posted when we were on holiday in Melbourne, Australia. We don't have IKEA here in New Zealand! Hubby is going back over in May/June so will get him to get more of that sort of thing when there. We would pay about 4x the price for that sort of thing here in NZ. I need to work out what I will do now where the fridge was and there is the angle change (does that make sense?).

Provided there is 1200mm clear between the breakfast bar and the opposite bench then by rights, you should have ample room and if that's the case, I think I would opt for the design with the kitchen on the eastern side. My reason; you get a much greater feeling of open plan by having the dining and lounge on the North/South plane. I like the large WIP in this one - on paper at least. The second plan somehow feels wrong. I personally don't like the idea of having the breakfast bar being located in the lounge. If it were me though, I would ask for a 3D CAD plan of both kitchens [to walk through on the computer] before making up my mind on which one to opt for as it gives you a much clearer vision of what the finished kitchen will be like rather than looking at a flat plan.
