An office space is a bad idea. Nosey office mates or neighbors. Shared toilet. Noise. Cramped. For the same price as an office, I rented an apartment in a great complex. Quiet as can be. Private. Comfortable.
Getting together with other traders and renting a space is not that difficult. But to meet like-minded traders who are able to support and foster each other's growth is not easy. What often happens is that the office environment turns out to be no better than a chatroom or a forum and there is no real benefit.
