I kill two birds with one stone: my apartment is actually two in disguise. I have two front doors, one leading to a third of the apartment (it's a rather large 4-bed) which is quite literally closed off from the rest by simply locking the internal door that connects the two. It may sound silly to have to literally exit the apartment to enter the office when it's literally next door, but it does have some value. Also it makes it much easier for tax purposes. Consequently a third of my rent is paid by my company, because it rents it as office space. Maybe it sounds weird or immoral or whatever, but it truly is office space and 100% legit, it just happens to be I'm also the landlord.
