I would suggest you take out the cabinet that is to the right of the stove and use it elsewhere in the house -- perhaps in the bathroom or dining room with a hutch above it. Then, I would suggest you have someone install a lazy susan cabinet in the corner between the sink counter and the stove, meaning you would move the stove down a bit and have a small cabinet/counter top to the right of the stove. I would suggest you have the cabinets refinished in white and then paint the walls a pastel you like. If you would prefer white walls, then add white-painted crown molding and paint the ceiling a light neutral blue, such as Sherwin Williams Niagara Falls Blue. Then, I would suggest you choose a favorite accent color and use this sparingly in accessories like towels, pot holders, small vases or floral arrangements, and a valence above the triple windows. For a genuine 1940s look, you might have white ceramic square tiles with a rectangular red border installed as a back splash behind and above the stove. If you are replacing counter tops, I would suggest a light color such as white with a beige or light grey vein or striation for some sort of pattern. You might be able to find the same color and design in floor tile OR opt for a wood floor as another poster suggested.

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.

I recommend having the TV in a separate well-insulated room if you're having a great room/open floor plan. We combined a play room/media room and put french doors on so TV is visible from great room/kitchen, but noise is contained. Also, love having hand-scraped distressed wood floors that have withstood our kids and dog. Quartz counters have been proven crayon/paint/marker/anything-resistant. A mudroom with cabinets helps contain backpacks and coats by entry (ours is by garage entry since that's how we get in the house). Maximize built- in storage in every room--it's nice to have the option to store away all the toys/school projects/art supplies where they're used and played with. Consequently, we also put in a walk in pantry to store packaged foods and craft supplies. Can keep going, but these are good to start with. Goodluck!

@thinkforothers, Ha-ha that's so funny about your American trip but yes I use the duvet as a top sheet. As for getting the dooda back into the cover, I have a pretty simple method and it doesn't take allot of effort nor does it include being swallowed up by the duvet in the process as you said ha-ha..... but there is a bit of back and forth around the bed. I flick the duvet open onto the bed, I grab the one corner of the doona head up towards the respective corner and pull the duvet back towards my hand a little too and place it down, repeat on the other side, then I grab each top corner seperately holding the doona firmly in the corner and pull it up to the headboard, whilst walking back to the end of the bed I lift the cover slightly, allowing the doona to get further swallowed up by the cover, then I'm left with slipping either corner of the doona into the duvet. I do up the buttons then holding the bottom of the duvet, I flick the cover, towards the headboard, so that the doona edges forward in the cover and even flick the doona on both sides of the bed left to right and vice versa and it's usually perfect. Its very easy doing a single doona by again spreading the duvet over the bed, grab the doona corners, one in each hand, walk them up to the corners, lay it down then pick up the dooda by the top corners and shake a few times just straight down, even stand on a safe stool or on the bed and you will usually find the duvet with eaze it's way down with just the bottom corners to slip in and again voila!!! Unfortunately, when I bought two of my duvet sets from Ezibuy, I bought NZ king which is a bit wider that an Australian king size and I didn't know that at the time and I have a bit of slack on the sides but it doesn't cause any problems and what I mean by this is, that the doona doesn't slip all the way to the left or right, it does stay in place. Hope that explanation was clear, I should do a video ha-ha Cheers, Barbara
