Ontario mom, I am posting pictures of our "blue room" that isn't actually painted blue. I think that the blue of Scandinavian Christmas plates looks best on a color other than blue. The white Holly Kay linked to, or something similar, would be beautiful for pine furniture and floors. This is a sort of montage of photos of the room. I have about 100 plates and cannot display them all, but they were the starting point for the room. It was already painted this gold color. I used other blue and white pieces i already owned (urns, vases, Foo dogs, etc) in this room as well. We purchase the oil of children on the beach and I framed it myself in the plein air style. Sorry for the horrible iPhone photos....this shows the plates above the headboard. We used DS2's childhood furniture (armoire and dark pine single size sleigh bed ). We recently put rustic white oak floors in the room and I added this blue and taupe-y gray rug: Closer of plates above headboard (these are Norwegian) and other blue and white stuff on shelf in bed alcove: In the corner is a display thing bought at Ballard Back Room in Atlanta (their discount place). They called it a bookcase but it is perfect for displaying plates in a corner! This is an interesting side table my mother gave me for my birthday about seven years ago. It is a mosaic top made up of broken pieces of blue and white china. On it is a lamp that was in my childhood room...a little too "good" for the rest of the room, but I wanted to use what I had. The bedding is a discontinued Ralph Lauren pattern I found on ebay. They incorporate shades of navy, royal and light blue, which is a perfect foil for the plates. I use the white matellasse cover on the bed with the comforter folded up at the foot. Hope these photos help you envision a blue and white room :-)

I'm guessing since you are painting the dresser you like dyi or you are on a budget. I think a tuff head board, paint furniture white and some pretty drapes. This is a link to dyi tuff headboard and scroll down and she has similar gray color scheme going with white bedside tables grey tuff headboard. You could go with other color that compliment your gray walls/carpet If you scroll the link she shows a picture of the room. Its older post 2013 but I'm still seeing tuff beds so it should be ok ;) I'm not a designer and not trendy so it may be consider out of date LOL I'm sure others will let you know Have fun and make the space something that's peaceful for you https://www.thriftydecorchick.com/2013/07/diy-tufted-headboard-tutorial.html

Multiple thoughts, not all in line with the majority: - Five bedrooms is a huge house. The potential field of buyers who want the space and upkeep of a house that large (and who can afford it) is relatively small. More plainly, You're looking to build a house that only a small percentage of buyers can afford to buy. Wanting a thing and being able to afford a thing aren't the same. Your pool of resale buyers will be small, so selling could take a long time, or you might be forced to take less than you want. - Yes, people will like the idea of a "master up and a master down": live-in space for mom, space for a live-in nanny or elder care-giver. Plenty of reasons people would like the space. But the real question is, Will your resale buyer be willing to pay what it will cost you to build it? Personally, I think you'll attract plenty of interest, but you may not attract the necessary dollars at resale to make this worthwhile. - How old are these small children? By the time you finish building this house, they'll probably be at least a year older -- how long will you want to have bedrooms close by? - I'm a highly practical person: you're talking about a short time when kids are small. To save money, could you sleep in a "non-master" upstairs for this short time, then move downstairs? - How "master" do you see your "masters"? That is, when you say "master bedroom", are you envisioning a slightly larger room with a modest walk-in closet and a private 3-piece bath ... or does "master" to you mean a spacious room with a seating area, a massive closet and a luxury bath? The question isn't just, "Should I have two masters?" It's, "Just how much will I put into a master?" Your own vision of "how much" can make a world of difference in this question. - Don't overbuild for your neighborhood. Remember that the biggest, most expensive house in the neighborhood is "drawn down" by the more modest houses that surround it. - Summary: Don't be caught up in just whether this is a desirable idea -- it is. Consider first and foremost whether it is an economically viable idea.
