Hi @Linamints , you can use the 'ConstrainFloorElevation' true/false cheat to make perfectly functioning highrise buildings.
You usually have 1or 2 levels on the bottom that sims can use, the middle part is just empty space but on the top you can build further usable levels.
A skinny tower will obviously give you hardly any floor space especially as you will need the elevators that came with Late Night for sims to reach the top.
This screenshot shows what a basic 8x8 tower on a 10x10 base could look like.

It has is a fair bit of space whether you would want to use it for residential or community purposes.
Please don't hesitate to ask if you'd need more info on how to use the CFE cheat for highrise builds.
Happy simming :D
