The first is a 35 foot tall tower, meant to be placed on exterior wall. The exterior is on the left and the interior of the walls is to the right. The first floor has no windows, just a door. The door opens inward while a pair of barred doors open outward.
I haven't filled in the walls because I don't know what pattern I want to use. The walls are tapered from bottom to top so this is not a good design against siege engines. The bottom might hold, but the top could be collapsed by catapults.
I drew no interior designs, not even stairs, so I can adapt them for different purposes.
I like the details on the doorway at ground level, except I made a mistake. The scale in the profile view is one square equals 10 feet, while the side view is one square equals 5. The door is a massive 10 feet wide. As you can see from the tiny doodle on the upper right, I tried to fix that by making the door multifunction with two sally doors.
Additionally, I didn't like the way the windows looked. I changed styles and neither one looks very good. Plus, with the tower being so tall, there has to be a way to reach the walls.
That won't do, so I decided to redraw it.
I think that I can fix the door digitally, but maybe I'll just redraw that level or the whole tower tonight.
I really like this design and I'll use it to work up some designs in both Inkscape and Worldographer.
