Suggestion for lots available in future content

Personally, I'd like to see multi purpose lots.
The ability to have a lot that is 3 things at once would solve a lot of the 'too few lots' problem.
Imagine having a cafe and an arcade on the ground level, and an apartment above.
Or a bar with two apartments above it.
A restaurant with a nightclub in the basement, and a detective agency upstairs.

Combining our ideas would be even better still!
