Open-Plan Offices: What Occupational Health Research Reports About the Tradeoffs

officeworkergonomicsresearch-summary

Open-plan office layouts have been a dominant workplace design choice since the mid-20th century, with periodic waves of adoption and reconsideration. This summary pulls from occupational health research, ergonomics literature, and workplace design studies to describe what the evidence says about open-plan offices and the design variations that have evolved to address identified tradeoffs.

This article does not claim personal experience working in open-plan offices. The information below reflects what published occupational health and workplace design research describe.

The Original Rationale

The open-plan office emerged in the 1950s and 1960s, influenced by the German Quickborner Team’s “office landscape” concepts and the Action Office systems developed by Robert Propst for Herman Miller. The original rationale included:

  • Reduced real estate costs per worker (less individual office space)
  • Easier communication and collaboration among team members
  • More flexible use of space as teams and projects changed
  • A flatter, less hierarchical physical environment

These rationales were reasonable at the time. The early office design literature emphasized the benefits of visibility and easy interaction for collaborative work, and the cost-per-worker reductions were substantial.

What the early design literature did not adequately anticipate was the impact of these layouts on focused individual work, on acoustic privacy, and on the broader patterns of workplace stress that have since been documented.

What Occupational Health Research Reports

The published research on open-plan offices has accumulated substantially over the past several decades. Some consistent findings across studies:

Acoustic distraction is the most-cited issue: Multiple studies, including several summarized in NIOSH’s workplace stress resources, find that noise and conversational distraction are the primary complaints of open-plan office workers. Even moderate background speech has been shown in laboratory studies to disrupt focused cognitive work. The effect is amplified for tasks requiring sustained attention or complex problem-solving.

Reduced privacy affects both focus and wellbeing: Open-plan layouts reduce visual and acoustic privacy. Research summarized in occupational health journals has linked reduced privacy to higher reported stress, lower job satisfaction, and increased perception of surveillance.

Effects vary by work type: Open-plan layouts appear to affect different work types differently. Tasks requiring collaboration and quick communication (e.g., customer support teams, certain engineering teams) may benefit from open layouts. Tasks requiring sustained individual focus (e.g., writing, deep programming, analysis) are generally hindered.

Self-reported productivity effects are mixed: Studies of self-reported productivity in open-plan vs. private offices show mixed results. Some workers report higher productivity in open layouts (citing easier collaboration), others report lower (citing distraction). Individual variation is large.

Health effects are documented: A number of studies have found associations between open-plan office work and increased sick leave, increased reported stress symptoms, and reduced mental wellbeing. The relationships are correlational and complex, but consistent across studies.

The CDC’s NIOSH workplace stress resources, the OSHA workplace stress guidance, and the APA’s stress-related publications all reference this body of research when discussing open-plan office design considerations.

Design Variations Attempted to Address Tradeoffs

In response to the documented issues, several design variations have emerged:

Cubicles with partial walls: Low-walled cubicles attempt to preserve some of the cost and space efficiency of open layouts while providing visual and partial acoustic separation. Research on cubicles has found that they reduce some forms of distraction but still allow conversational noise to carry.

Activity-Based Working (ABW): A design approach where workers do not have assigned desks but instead choose workspaces based on the activity (focused work, collaboration, calls, breaks). The literature on ABW shows mixed effects; some studies report increased worker satisfaction and productivity, others report increased stress and reduced sense of belonging.

Hot desking: A specific implementation of ABW where workers choose any available desk on arrival. Research has linked hot desking to reduced sense of territorial ownership, increased time spent setting up each day, and in some studies reduced productivity.

Team zones or neighborhoods: Open-plan layouts organized into smaller team-specific zones with shared resources. The smaller group size reduces some distraction while preserving collaborative benefits.

Quiet zones or focus rooms: Dedicated spaces within open-plan offices for focused work. The effectiveness of these spaces depends on how they are scheduled, how clearly their purpose is communicated, and whether workers feel culturally permitted to use them.

Hybrid layouts: Combinations of private offices, small meeting rooms, focus rooms, and open collaboration areas. Many technology companies have adopted hybrid layouts as a response to the documented tradeoffs.

The research on these variations is less consistent than on the general open-vs-private question, partly because specific implementations vary widely.

Cognitive Load and Decision Fatigue

One specific concern that has received increased research attention is the cognitive load imposed by open-plan office environments. The constant monitoring of ambient activity, the frequent small interruptions, and the need to redirect attention repeatedly can produce what researchers call “attention residue” — leftover cognitive load from a previous task that reduces performance on the next.

The APA’s research summaries on workplace cognitive performance have highlighted this as an underappreciated cost of open-plan designs. Even short interruptions (a colleague asking a quick question, a phone ringing nearby) can require several minutes to fully recover from, particularly for tasks requiring deep concentration.

The cumulative effect of these micro-interruptions across a workday is substantial, even if each individual interruption seems minor.

What Workers Report

Aggregating worker satisfaction surveys and aggregated reviews of workplace design:

Common positive reports about open-plan offices:

  • Easier communication with team members
  • Sense of community and shared purpose
  • Lower real estate costs (which can fund other benefits)
  • Faster onboarding for new team members

Common negative reports:

  • Distraction from ambient noise
  • Lack of privacy for sensitive conversations
  • Reduced ability to focus on complex tasks
  • Increased stress and fatigue
  • Feeling of being watched or surveilled

The balance of these reports varies by industry, job function, and individual difference. The research suggests there is no universally optimal layout; the right design depends on the work being done and the people doing it.

Recommendations from the Literature

The occupational health and workplace design literature does not converge on a single recommendation but does suggest several principles:

  • Match the design to the work. Tasks requiring sustained individual focus benefit from private or quiet spaces. Tasks requiring frequent collaboration benefit from open access to teammates.
  • Provide choice. Workers differ in their needs and preferences. Providing a range of work settings (open, quiet, private) lets workers choose what fits their current task.
  • Manage acoustic environments carefully. Sound masking, acoustic panels, and white noise systems can reduce the cognitive impact of ambient noise.
  • Establish clear norms. Even in open layouts, norms about interruptions, meeting spaces, and quiet hours can substantially reduce friction.
  • Evaluate and iterate. Workspace design should be evaluated based on actual outcomes (productivity, wellbeing, retention) rather than assumed benefits.
