Offices are places where people transact their business. Business administration is the main reason for most offices. There are companies that have offices that take up whole buildings. Such huge corporations have massive operations that require extensive support. However, business startups will normally require much smaller office space which in many cases will comprise a single room from where to launch their operations. Money will often play a major role in the kind of office you eventually settle on. For startups that have tight budgets, cheaper rent for office space is the way to go.
