Would anyone be sleeping in the sleeping loft? If so, they have to go downstairs in the middle of the night to use the restroom (and also apparently shower- so they have to take all their clothes with them). Might make sense to find a plan with a bath upstairs and powder down.

The year 1973 comes to mind.

Even though some people may like the feature, I try to avoid the capability of sitting on the toilet and carry on a conversation with everyone sitting in the dining area in my designs.

You will be better off contacting a local architect to design a home with you that meets your needs and fits your site.

Yes, well, if someone had to take a #2 during the dinner party...party is over.

For 1000 square feet it does "feel" bigger. I have seen similar where the loft is a library or office and having a bath up there is not necessary.

The ext colors could be different.

If you are on a very strict budget maybe this would work. Otherwise as Mark says you can probably do better.

What exactly do you like about the house?

We are changing it to add a full shower bath upstairs and just a powder room downstairs. We like it because it's small, just the 2 of us, and great windows to overlook the Ozark Mountains. Yes, strict budget, and we are going to try to do most of the build ourselves.
