Is this it?

I did another take on the addition.   I think this one might be a go -- clean up the drawing & take it on the road.   I hope so anyway.

I put in more windows.   These are a bit lower than I am planning (top at 6'8", should be at 7').    I figured out how to set this value, but then forgot to actually do so.  Changing it is part of the cleanup.

 

 

I also figured out how to change the wall height & how to add a railing.    I changed the garage door to a pair of them, because that way there is a support between them for the upper floor.   I think it looks a little nicer too, but it means the wall inside moved over a little (to make a wider space for the doors).   This may change when I talk with the architect and the contractor.

The spacing between the windows is all 3', except for the middle one, which is 4'.    Also, the top floor of the present house isn't drawn in, just because I had started with a new drawing & didn't want to draw all those fiddley bits.

 

North side -- which is pretty close to invisible from the street.

 

 

Another view, looking down the deck cutout.   It will have a railing, but I forgot to put it in.   It's a french door to the porch (meaning it is all glass) and a window in the tower.

 

 

South side.  This is where I had to compromise.   The staircase and the windows I wanted to put in did not work together.   I finally decided to skip the windows on the main & top floor.   I put in small windows on the lower floor, since otherwise there is little natural light that comes down there.   The back door porch will cover over the existing basement window, so I want to have light coming into the hallway and through the basement door.   There is actually a window opening on the north side of the basement, which is presently filled with a board & the dryer vent, but I could replace it with a window that has glass -- and a hole for the dryer vent.

 

 

I may put up tromp l'oil windows, or solar panels, where the windows aren't, just for visual balance.   The basement level windows will be pretty much invisible from the street, so I think it will be ok that they are a different size.

 

Corner view -- the door is actually about 3' above ground level & will have a porch going up to it.

I discovered something else Floor Plan can do, which is to put in what it calls surfaces.   That is, one can have an elevation change without a wall, like a ledge.  This is what you see on the lower level.   The addition floor level is below the present basement level.   Rather than go down to the addition level & then go up to the basement, I put in a ledge that goes to the basement, then steps go down from that.    The addition level will be 16 (or 17) inches below the basement, so there may need to be a railing around the ledge.
