I like my first idea best as far as use of space. I know people say not to put toilets on an outside wall. We had one in our last house in Iowa, but we had 2X6 construction. I don't know how high your window is, but I'm guessing the toilet would fit under there. The shower would be 5 feet long or shorter if you want a wider space to get to the toilet. (kind of tight the way I have drawn). You could do a 5 and half foot long shower and do an angled door at the left end to allow room between the shower and toilet. The vanity would be about 7 feet long, unless you do a 60 inch vanity with a linen cabinet at the door. I would reverse entry door swing if you do that.. The second top right could work and you would still have a small closet. The bottom left plan would require waterproofing your front window. Hopefully someone will give you other ideas. The bottom right plan is bigger, but no closet. Each square equals 1 foot.

I also like color and for my master I used this rug in a 12x16. I paired it with a velvet teal/peacock headboard and a metallic crossweave wallpaper. I kept the bedcover simple because I already had lots of color. I picked a beige/gold and had a custom fitted bedspread done at Calico Corners. Drapes are a teal/peacock in silk Very hard to find color in the Houzz photos! I also searched for ideas and it was just an endless sea of boring beige and white. When I found the rug, it was my starting point for the bedroom.

It took me about a year to get mine done, with months to come up with a design and then more months waiting for the stuff.

I think people are gonna want to see more of your room/style!

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.
