I can't speak for the OP and everyone has their own reasons but - Do you have a roommate? Children? Now your house/apartment is looking like a mini-office with shared space. - Your house has one office. Where will your spouse/partner work? Most houses don't have two offices. - Maybe living in a small apartment is OK for people because they can get out to larger spaces. Want to live in a studio apartment and work there too? - Offices can have cafeterias and tend to have restaurants nearby. - habit
