The main purpose of an office environment is to support its occupants in performing their job. Work spaces in an office are typically used for conventional office activities such as reading, writing and computer work. There are nine generic types of work space, each supporting different activities. In addition to individual cubicles, there are also meeting rooms, lounges, and spaces for support activities, such as photocopying and filing. Some offices also have a kitchen area where workers can make their lunches. There are many different ways of arranging the space in an office and whilst these vary according to function, managerial fashions and the culture of specific companies can be even more important. While offices can be built in almost any location and in almost any building, some modern requirements for offices make this more difficult, such as requirements for light, networking, and security. The primary purpose of an office building is to provide a workplace and working environment primarily for administrative and managerial workers. These workers usually occupy set areas within the office building, and usually are provided with desks, PCs and other equipment they may need within these areas.
