A hot desk, monthly

For the person in most days who does not mind where they sit. You get an open desk on either floor whenever you come, round-the-clock fob access, a locker to leave your things in, meeting-room hours every month, and the registered address for your company. It starts the day you ask and stops the day you say so, with no notice period and no joining fee. When you have outgrown turning up and want a desk that is always yours, the fixed desk is the next step up.
