One issue with creating a physical space is you know eventually you will need to expand in currently unforeseen ways. So ideally you need to obtain a larger space than you immediately need, or be prepared to move multiple times.
To create a presence, the longer you stay at one location the better. But reserved space is either wasted or will fill with junk.
Another option has occurred though. If access permits, partition and sub-let the reserved space. Storage? Co-working space/offices maybe?
