Open Plan Office: Pros, Cons and How to Make It Work

The open plan office is the default for most modern workplaces, and also the most criticised. It promises efficiency, visibility and easy collaboration; it is blamed for noise, distraction and a loss of privacy. Both views are partly right. Whether an open floor succeeds depends far more on how it is designed and supported than on the concept itself.

This article sets out the genuine advantages and disadvantages, the design measures that address the main problems, and the building and approval considerations that apply when an open floor is fitted out in Singapore.

Where open office floors came from

Open office floors are not new. Large open drafting and clerical halls existed in the early twentieth century, and the German Bürolandschaft (office landscape) movement of the late 1950s and 1960s arranged desks in organic clusters on open floors to reflect communication patterns. Later decades brought cubicle systems and, eventually, today’s benching layouts with low or no screens. Each generation responded to cost pressure, new technology and changing ideas about how organisations work.

The current form is shaped by deep floor plates, raised floors and accessible ceilings that make services easy to distribute, and by the steady reduction of paper. It is a sensible response to these conditions, provided it is not applied without the supporting spaces that the work requires.

The advantages of open plan

Space efficiency. Without walls and corridors around each person, more desks fit on a floor, lowering occupancy cost.
Daylight and views. Light from the façade reaches deeper into the plan when it is not blocked by private rooms.
Flexibility. Teams can be regrouped by moving furniture rather than walls, and services in raised floors or ceilings are easily reconnected.
Visibility and informal contact. People can see who is in and ask quick questions, which helps newer staff learn and supports some forms of teamwork.
Lower fit-out and reinstatement scope. Fewer partitions generally mean simpler construction and less to remove at the end of the lease.

The disadvantages of open plan

The main problem is sound. Speech is the most distracting noise for knowledge work, because the brain involuntarily follows intelligible conversation. In a hard-surfaced open floor, voices carry across many desks. Visual distraction from movement and the feeling of being observed add to the effect. Several studies of offices that moved to open plan have reported a reduction rather than an increase in face-to-face interaction, as people withdraw into headphones and messaging.

Other issues follow. Confidential calls and conversations have nowhere to go. Temperature and lighting cannot be adjusted individually. Illness spreads more easily in dense settings. None of these is inevitable, but each has to be addressed deliberately in the design.

Acoustic design for an open plan office

Acoustics in open areas works on three principles, often summarised as absorb, block and cover. Absorption reduces reflected sound; a high-performance acoustic ceiling is the most effective single element, followed by carpet and vertical absorbers such as acoustic panels on walls, screens and furniture. Blocking uses screens, storage and distance to interrupt direct sound between neighbours. Covering, or sound masking, introduces a low, even background sound that reduces the intelligibility of distant speech.

Planning matters as much as materials. Place noisy functions such as the pantry, reception, printers and collaboration tables away from focus areas. Keep busy routes at the edge of desk groups rather than through them. Provide enough enclosed rooms, particularly small ones for calls, so conversations move out of the open floor. Partitions to those rooms should be sealed above the ceiling, as described in our article on office partitions.

Lighting, comfort and planning density

Open floors need even, low-glare ambient lighting suitable for screens, with control zoned so that areas near the façade can respond to daylight. Workstations should be oriented so that screens are not directly facing or backing onto unshaded glazing. Thermal comfort depends on how air-conditioning zones relate to desk groups; a uniform layout under well-distributed diffusers performs better than desks crowded against a single zone.

Density is a choice, not a given. Packing desks to the maximum the floor will take leaves no room for the supporting settings that make open plan tolerable. A slightly lower desk count with a better mix of rooms, booths and quiet zones often delivers more useful capacity than a floor packed to the limit. Our article on office layout types compares the alternatives.

Fit-out considerations in Singapore

An open floor simplifies some approvals but does not remove them. Desk layouts must keep escape routes clear and within the travel distances set by the SCDF Fire Code, and any rooms added within the open area can affect sprinkler coverage, detection and exit signage. Works affecting fire safety provisions generally require SCDF plan approval or, for qualifying minor works in shops and offices, a lodgement by a Qualified Person. The landlord’s fit-out guidelines will also set out how services may be altered and what must be reinstated.

From a structural point of view, open plans are usually benign: loads are spread evenly across the floor. Problems arise where heavy items are concentrated, such as banks of filing, large printers, server racks or a feature wall, or where an internal staircase is proposed to link floors. Those cases warrant an early check through our structural engineering consultancy.

Frequently asked questions

Are open plan offices bad for productivity?

Not inherently. They can reduce concentration when they are noisy and lack quiet or enclosed space. With good acoustic treatment, sensible zoning and enough rooms for calls and focused work, many organisations work effectively in open plan.

How do you reduce noise in an open plan office?

Install a sound-absorbing ceiling, use carpet and acoustic panels, separate noisy and quiet zones, provide enclosed rooms and booths for calls, and consider sound masking to reduce the intelligibility of distant conversations.

Is open plan cheaper to fit out?

Generally it involves fewer partitions and simpler services, which reduces construction scope. Savings can be offset by the need for good acoustic treatment, booths and meeting rooms, so the comparison should be made on a complete design.

What is the alternative to an open plan office?

Common alternatives include cellular layouts with private rooms, team neighbourhoods with their own support spaces, and activity-based working where staff choose from a range of settings. Many offices combine elements of each.
