I work remotely and rent an office in town. It's a 15 minute walk from my house, a decent size (~22m^2), all my own, and well set up. I love it and pay gladly but I it's not possible for everyone.

I used to have a garden office but my wife now needs her own space for her work so I took the rented space.

A dedicated space is a must if you're working remotely. Either at home or offsite.

I have no objection to going into the office for well defined, productive meetings like project kick-offs though. I still believe they're the best way to collaborate on big planning tasks, even after having worked remotely for over 10 years.
