Modern open office designs are not an independent room design category but, as a rule, a combination of various office areas. They combine different kinds of work and communication zones and thus enable employees to choose the work or common-room area that is the best setting for their current activities.

According to ASR A1.2, the planning of open office designs should begin with the following minimum areas:

  • In open-plan areas: 12 m2 to 15 m2
  • In cellular offices: 8 m2 to 10 m2

Independently of the room design, the only rooms that may be used are those 'whose floor space comprises at least 8 m2 for the first workplace in a room and at least 6 m2 for each additional workplace'. In addition, every employee must be provided with at least 12 m3 of air space. (Note: These requirements do not apply to conference and training rooms.)
