You can have all of these things and much more living in a small apartment in a city. The shop will probably be a basement or a garage and the greenhouse will be on your roof or at a community garden, but apartments with multiple rooms are not difficult to p in cities lol.
It's basically a space with a door that's dedicated to one of the inhabitants and their interests.
Even the closest of couples needs their own space occasionally, and having a "man cave" or "she shed" (yes, sadly they're needlessly gendered) provides that environment. They can also frequently double as a WFH office.

Sure, but at what cost? How much does a 4 bedroom apartment cost in most cities? $4k a month?
An example: I want to sand and revarnish a chest of drawers we have. If I do that inside the apartment I'll have dust everywhere and then the stink of varnish will pervade the space. There are also no suitable shared spaces for me to use.
It is what it is, I accept it as a price of city life. But it's definitely a downside.
