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.

What emotion do you want to feel in the room? Calm? Energized? Happy? What colors do you associate with the emotion you want to have in the room? Choose a bed covering first. It is much easier to match paint to a bed covering than it is to try to find a bedcover to match paint.

I meant to upload photos of the wallpaper and cushions.

Hi Linda. The Resene Merino on the walls may make the trims possibly look more creamy. If you intend to paint your trims, doors etc, I usually tell people to use a stark white like Resene Alabaster because if you change your wall colour again at a later date it will still look good. If you know the trim colour let me know. The inspiration picture of white works well because it is broken up by lots of natural textures and materials.
