The first thing to consider when deciding how much office space you need is the maturity of your business. Are you looking for your first office after starting your business from home? Are you the sole employee and founder or do you have co-founders plus employees who work remotely? At this stage, growth projections are hard to fathom and the smaller the investment in the rent the better. If you are moving from an office due to expansion and have a few employees, you may have a better scope of things and project your growth and needs more accurately. You should consider the role of your employees and if any of your senior managers need an individual office. Space and desk allocation can be seen as favoritism, so be sure to assign them with a fair method in mind.
