Thanks for the good responces. There was a really nice lift, some of which I hadn't thought of.

That's not a tower, Tigycho, that's a palace!
Seriously, what kind of structure are we talking here? Is this an actual tower--which would have far less room than some of the suggestions so far--or something more like a keep or full-scale castle...or even a tower-shaped demi-plane....?
Likely an actual tower. I was thinking about what shape, as I didn't want anything boring -- like a cylinder, which has been done.
I was thinking about a pentagon, went over to math world's description of the pentagon, and found the pentaflake -- which is a geometers playtoy. Here's the link:

That should be the basic shape of the "tower", which suggests certain designs. For instance, it makes since to have 5 guest rooms, all on one floor. Each pentagon shaped.
Also, I now thing I know basically how going up and down will work -- some sort of device in the center of the center chamber, where gravity is lessened. Grab a pentagon shaped-pole, and move upwards. Sure, I don't know of a spell to do that, but I'll figure something out.
To give the sort of size, I'm thinking each "chamber" to be about 250 square feet. Which, if my calculations from earlier today were correct, makes the total thing about 50 feet long. Actually, that doesn't sound right at all. The 50 feet, I mean. I'll have to redo the math and find out.
I'm thinking just one below ground for storage -- the wine cellar, a room stocked with food, that sort of stuff. Possibly an armory, at least of the mundane equipment. Each 250 square feet. I'm not sure if that is enough space -- should I up it?
The idea isn't just a place for a single wizard, but something between that and the Paper Street Soap Company. That is, its expected and even desired that new magicians will come to learn more of magic. So, somewhere between one and 20 people, I imagine.
More thoughts?
