Okay, so I was able to adjust the
last design, adding in the water heater, HVAC, electrical panel, electrical meter, and vent for the dryer.
Modified floor plan. See, I fixed that one exterior wall corner.

Back, Aerial and Virtual Visitor views. Electrical meter and dryer vent are visible here.
A view of the Great Room with different views of the reduced back closet, and the newly added water heater closet.
I couldn't figure out where to put the HVAC unit, and ended up putting it into the bedroom since this house only needs a small one.

This is a view of inside the bedroom closet, showing the electrical panel as this was really the only place I could think of put it as well. This electrical panel might have more switches than would strictly be needed in a house like this but... oh, well. [:D]
