Building Rec Deck

How do I properly draw a building with multiple towers and a rec deck with an elevated pool & tennis courts? Do I draw the podium and each tower as individual ways and combine them into a relation? Can I also draw the tennis courts and pool even though they are multiple stories above street level?
