Office space planning describes the methods used to design and arrange office layouts so that staff can work together in departmental and team groupings, providing the best opportunity for efficient work flow, communication and supervision.
In many organisations, office layouts are subject to frequent changes. This process is referred to as churn rate, expressed as the percentage of the staff moved during a year.
Statutory requirements related to office layouts will vary in different countries but examples may include: the minimum amount of space to be provided per staff member; fire safety arrangements; lighting levels; signage; ventilation; temperature control and welfare arrangements.
Office layout designs should provide an environment suitable for the business needs of the organisation. For example: call centres undertake their business ‘on screen’ and require small desk areas per staff member, minimum document storage, and may have limited requirements for photocopying facilities and printing. In contrast, companies handling paper based documentation will require larger desks for their staff, storage for records, archive facilities, photocopying and printing facilities close to hand.
Organizations often have a policy on the minimum standards of accommodation for each staff grade. Administration staff may work in open plan offices whereas managers may have individual offices, sized on a seniority basis. In open plan offices screens are sometimes used between desks to reduce noise and provide an element of privacy.
The grouping of staff in teams often provides the best option for inter-communication and/or supervision and is a key factor in office layout design. However, where space is at a premium it may be difficult to accommodate a workgroup in a given area, and the solution often involves making space by moving others. These types of move may be complex and disruptive as there is often a chain of events involved.

Each desk in an office may require a telephone and computer. In large offices the power and data cables may be run under a raised floor or above in a suspended ceiling, to the desk. Another alternative in smaller offices is to use dado trunking around the wall. Other alternatives are to use ceiling power poles which can assist space planning of desks away from perimeter walls
Open plan offices are often divided up into smaller offices for managers, meeting rooms, etc. When this happens the designer has to take into account several factors  including:
- Heating/cooling zoning
- Lighting and light switches
- Emergency lighting
- Small power
- Voice and data cabling
- Fire alarms
- Fire stopping
- Fire escape routes
Staff welfare facilities
Office staff require access to basic welfare facilities in an office such as toilets and drinking water. Consideration may also be given to vending, catering or a place where staff can make a drink and take a break from their desk.
