I'm designing a bed that is to have drawers under it. It never occurred to
me until I put pencil to paper (well mouse to CAD), but would the bed still
have a box spring, or just the mattress?

Any other useful information will be much appreciated.

The only thing I would suggest is check the warranty on your mattress
as some require a box spring.
Other than that it's just a matter of height. I have a friend who had
a similar bed frame for a water bed. He later went to a mattress but
with a box spring his wife (she's 4' 10") had a difficult time getting
into the bed. They ended up eliminating the box spring altogether.
