Most work from home careers only need a computer.
I have a workplace set up for rabbithole careers too, so they can go there during their time off and I can pretend they are at work for storytelling. They form clubs with their work colleagues and have a club gathering. It's actually set as a library as I don't need a bartender or cafe person there.
There is a basement (mainly for criminals) with fitness items, a computer and a woodwork bench, next floor up has the chef stations, fridge etc and a reception area where the main toilets are, with a 'waiting' area which contains chess and bookcases. Next floor up is for artists; easels, digital sketch pads and items set up for them to paint. Next floor up has computers and spy-type gadgets, then the top floor is for general office workers/education with computers, draft table room (maybe for civil designer and the home decorator), coffee machines etc.
I have a separate army base for military, which is set up in Strangerville as part of the story there. For photographers, I have a separate Lot which is also for actors, it has pretend 'scenes' with cameras, lots of backgrounds for photo shoots, dressing rooms etc.
