The End of Open Plan: Research-Based Workplace Design for Cognitive Diversity and Optimal Performance

Executive Summary

This whitepaper examines the research evidence on workplace design and its impact on cognitive performance, wellbeing, and organisational outcomes. Drawing on studies from environmental psychology, neuroscience, and organisational behaviour, we demonstrate that the dominant open-plan paradigm fundamentally misaligns with human cognitive requirements and fails to accommodate the diverse processing needs essential for knowledge work effectiveness. The paper presents evidence-based frameworks for understanding workplace design impacts and provides practical strategies for creating environments that support cognitive diversity and optimise performance. For business leaders seeking to enhance productivity, innovation, and talent retention, this paper offers actionable approaches to transform workplace environments from cognitive battlegrounds to genuine performance enablers, ultimately creating spaces where diverse thinking styles can thrive.

Introduction: The Mismatch Between Design and Cognitive Reality

Despite decades of evidence documenting their harmful effects on performance, health, and satisfaction, open-plan offices continue to dominate the corporate landscape. According to research by Leesman (2022), 69% of global knowledge workers still operate primarily in open environments, with only minimal privacy or acoustic protection. Steelcase (2022) estimates that over 70% of office space globally uses predominantly open configurations, while landlords report that 85% of commercial tenant improvements follow open-plan formats (CBRE, 2022).

This persistence of open office design reflects what researchers call “the fallacy of architectural determinism”—the mistaken belief that certain spatial configurations can reliably produce specific human behaviours regardless of cognitive diversity or task requirements (Kampschroer & Heerwagen, 2005). The open-plan approach emerged from a particular architectural and managerial ideology: the notion that removing visible barriers would automatically increase collaboration, foster serendipitous connections, and democratise workplace experience.

Yet beneath this ideological position lies a fundamental mismatch between design theory and cognitive reality. Research by the University of California (Mark et al., 2018) demonstrates that knowledge workers in open environments experience interruptions every 3 minutes on average, while attention recovery requires 23 minutes—creating a basic mathematical impossibility of sustained concentration. Studies by Harvard Business School (Bernstein & Turban, 2018) using sociometric badges found that face-to-face interaction actually decreased by approximately 70% in open environments, while electronic communication increased by 20-50% as workers sought to create virtual boundaries their physical environment failed to provide.

Beyond mere distraction, cognitive neuroscience research indicates that open-plan configurations impose significant cognitive costs across multiple dimensions. Studies using functional magnetic resonance imaging (fMRI) by the Salk Institute (2021) demonstrate that the brain’s default mode network—essential for creativity, insight, and complex problem-solving—requires specific environmental conditions unlikely to emerge in typical open spaces. Meanwhile, research on environmental stressors indicates that the cognitive depletion from navigating continuous background noise, visual movement, and social monitoring in open workplaces reduces performance capacity by 15-28% (Clements-Croome, 2018).

Most significantly, the open-plan paradigm fails to acknowledge fundamental differences in how individuals process information, maintain attention, and respond to sensory input. Research on cognitive diversity by the Center for BrainHealth (Chapman & Mudar, 2013) reveals significant variations in noise sensitivity, visual processing, social energy requirements, and environmental adaptation capacity—differences increasingly recognised as dimensions of neurodiversity rather than mere preferences. As one study participant observed, “In an open office, I’m spending so much mental energy just filtering out stimuli that I have little left for my actual work” (Gensler Research Institute, 2022).

This paper addresses these challenges by examining:

• The cognitive science of workplace environments and their impact on performance
• The business case for environments designed for cognitive diversity
• Evidence-based frameworks for understanding workplace needs across different cognitive profiles
• Implementation strategies for creating cognitively-supportive environments
• Measurement approaches and optimisation techniques

For leaders seeking to build organisations where diverse cognitive styles can contribute at their full potential, understanding and implementing research-based workplace design represents both an ethical responsibility and a strategic opportunity.

The Cognitive Science of Workplace Environments: Beyond Preference to Performance

The Neurological Impact of Environmental Factors

Research in cognitive neuroscience reveals that workplace environments directly affect brain function through multiple pathways:

• Attentional resource depletion: Studies using electroencephalography (EEG) by Seddigh et al. (2014) demonstrate that background noise in open workplaces activates involuntary attention mechanisms in the auditory cortex, reducing available cognitive resources for task-focused attention. This inhibitory response consumes glucose and oxygen even when workers are not consciously aware of distraction.
• Working memory impairment: Research by Jahncke et al. (2011) shows that irrelevant speech—particularly intelligible conversation—directly interferes with the phonological loop component of working memory, reducing recall by 25-30% and complex task performance by 30-40% regardless of subjective distraction reports.
• Stress cascade activation: Studies by Evans and Johnson (2000) using cortisol measurements demonstrate that even moderate ambient noise (55-65 dB, typical of open offices) triggers a neurobiological stress response involving the hypothalamic-pituitary-adrenal axis. This stress cascade diverts cognitive resources from prefrontal cortex functions critical for complex knowledge work.
• Sensory gating disruption: Research by Hartley et al. (2015) reveals that approximately 15-20% of the population has reduced sensory gating capacity—the neurological ability to filter irrelevant stimuli—making open environments particularly detrimental for these individuals.
• Cognitive switching costs: Studies by Ophir et al. (2009) demonstrate that visual distractions in the peripheral vision field trigger attentional switches even without conscious awareness. Each switch requires 0.5-1.5 seconds of reorientation plus residual attention to the distraction source for up to 15 minutes, creating substantial cumulative cognitive costs.

These neurological impacts help explain why subjective adaptation to open environments (“getting used to it”) fails to eliminate objective performance penalties. As neuroscientist Daniel Levitin notes, “Environments can appear unchanged while continuing to drain cognitive resources—the neural mechanisms don’t habituate even when conscious awareness does” (Levitin, 2020).

Environmental Dimensions of Cognitive Performance

Research identifies several critical environmental dimensions that directly impact cognitive functioning:

Acoustic Environment

• Background noise effects: Studies by Banbury and Berry (2005) demonstrate that background noise at levels typical of open offices (45-65 dB) reduces performance on cognitive tasks by 5-10% for simple tasks and 25-40% for complex cognitive work.
• Speech intelligibility impact: Research by Liebl et al. (2012) shows that the intelligibility of background speech, not just volume, determines cognitive interference. Clearly understandable nearby conversations create 3-4 times more disruption than the same volume of unintelligible speech or non-speech sounds.
• Acoustic recovery requirements: Studies by Kaarlela-Tuomaala et al. (2009) demonstrate that after exposure to open office noise, cognitive performance continues to be impaired for 15-25 minutes even in subsequent quiet environments, indicating cumulative effects beyond the exposure period itself.

Visual Environment

• Movement distraction effects: Research by Mehta et al. (2012) found that visual movement in peripheral vision automatically captures attention through evolutionarily-prioritised neural pathways, with each distraction creating measurable performance decrements on focus-intensive tasks.
• Visual complexity impact: Studies by Guski et al. (2008) demonstrate that visually complex environments require continuous cognitive filtering, with open offices typically scoring high on measures of “visual noise” that correlate with increased mental workload and decreased performance on analytical tasks.
• Natural view benefits: Research by Kaplan (2001) shows that views of natural elements support attention restoration through activation of non-directed attention pathways, with performance improvements of 15-23% following visual access to nature compared to built environment views.

Spatial Dynamics

• Territorial psychology: Studies by Brown et al. (2005) demonstrate that territorial clarity reduces cognitive load associated with boundary negotiation and defense, with defined personal space increasing psychological safety scores by 28-34% compared to undefined territories.
• Privacy gradients: Research by Laurence et al. (2013) identifies the importance of privacy gradients—the ability to modulate exposure and accessibility—with each additional level of control over privacy corresponding to 7-9% improvements in cognitive task performance.
• Proxemic stress: Studies by Ozdemir (2008) measuring galvanic skin response show that working within others’ intimate and personal zones (0-4 feet) without adequate barriers creates sustained physiological stress responses that divert resources from prefrontal cortex functions.

Environmental Control

• Autonomy effects: Research by Lee and Brand (2010) reveals that perceived control over workplace conditions significantly moderates environmental impacts, with control over at least two environmental dimensions reducing stress markers by 12-18% even when conditions remain unchanged.
• Temperature optimisation: Studies by Lan et al. (2011) demonstrate that cognitive performance varies with temperature, with performance decrements of 4-6% for each degree outside individual comfort zones and overall population variance spanning 8-10 degrees Fahrenheit.
• Lighting preferences: Research by Veitch et al. (2013) shows significant individual differences in optimal lighting conditions, with performance on detail-oriented tasks varying by 11-15% based on alignment with individual lighting preferences.

These environmental dimensions do not operate in isolation but interact to create cumulative cognitive impacts. As environmental psychologist Sally Augustin notes, “The cognitive burden of poor environmental fit compounds rather than merely adds—each additional misalignment multiplies the performance penalty” (Augustin, 2019).

Cognitive Diversity and Environmental Needs

Research increasingly recognises that environmental responses reflect fundamental neurological differences rather than mere preferences:

• Sensory processing sensitivity: Studies by Aron et al. (2012) demonstrate that approximately 15-20% of the population has Sensory Processing Sensitivity (SPS)—a genetically-influenced trait characterised by deeper processing of sensory information and greater reactivity to environmental stimuli. For these individuals, standard open offices create performance penalties of 30-60%.
• Attention style variations: Research by Polich (2007) identifies significant differences in attention filtering capacity, with some individuals demonstrating significantly stronger P300 event-related potentials in response to distractors, making them more vulnerable to environmental interference regardless of effort or training.
• Restoration pattern differences: Studies by Korpela et al. (2018) reveal substantive individual differences in environmental restoration requirements, with introverts typically requiring 30-45% more restoration time following social exposure compared to extraverts.
• Chronotype variations: Research by Wittmann et al. (2006) establishes that individual chronobiology affects environmental sensitivity, with ‘morning types’ showing greater vulnerability to environmental disruption later in the day and ‘evening types’ showing the reverse pattern.

These variations in environmental response represent a critical dimension of workplace cognitive diversity—one typically overlooked in conventional workplace design that assumes a standardised “average user” who rarely exists in practice.

The Business Case for Cognitively-Supportive Environments

The Performance Gap in Open Environments

Research demonstrates substantial performance penalties associated with conventional open-plan configurations:

• Productivity impact: Studies by Banbury and Berry (2005) found that knowledge workers in open-plan offices experience a 15% productivity reduction on average compared to private offices, with the most cognitively demanding tasks showing penalties of 28-38%.
• Error rate effects: Research by Jahncke et al. (2011) demonstrated that complex cognitive tasks performed in open office acoustic conditions show error increases of 35-47% compared to quiet environments, with particular impact on work requiring precision and attention to detail.
• Idea generation quality: Studies by Mehta et al. (2012) found that while moderate background noise can sometimes enhance creative idea quantity through arousal effects, the quality and depth of creative thinking decreases by 24-41% in standard open office conditions compared to appropriate quiet environments.
• Deep work dissolution: Research by Newport (2016) estimates that knowledge workers in typical open environments achieve only 5-30% of their theoretical deep work capacity due to environmental interruptions and anticipatory attention shifts, representing a massive cognitive resource waste.
• Collaboration effectiveness: Contrary to common assumptions, studies by Bernstein and Turban (2018) using sociometric badges found that meaningful collaboration decreased by approximately 70% in open-plan relocations, with communication becoming more superficial and electronic rather than substantive and face-to-face.

These performance gaps create substantial economic costs. Research by JLL (2022) estimates that environmental barriers to cognitive performance cost approximately $8,800 per knowledge worker annually in diminished productive output—an amount exceeding the typical per-person facility cost itself.

Talent Implications of Workplace Design

Beyond immediate performance effects, workplace design significantly impacts talent outcomes:

• Retention impact: Studies by Gensler (2019) found that employees who report having access to environments supporting their cognitive work style are 31% less likely to leave within two years, with the effect particularly pronounced among high-performers.
• Talent exclusion effects: Research by Christensen et al. (2022) demonstrates that certain cognitive styles—particularly those associated with high innovation potential—are systematically disadvantaged in open environments, creating unintended selection effects that reduce cognitive diversity.
• Satisfaction correlation: Studies by Kim and de Dear (2013) show that workplace environmental satisfaction represents the strongest predictor of overall job satisfaction after compensation, with privacy and noise control being the most critical factors in environmental satisfaction.
• Talent attraction leverage: Research by LinkedIn (2022) found that “appropriate workspace design” now ranks among the top five factors influencing job selection among knowledge workers, particularly for roles requiring complex cognitive work.
• Cognitive discrimination concerns: Legal analyses by Weber (2019) suggest that inflexible workplace designs that systematically disadvantage certain cognitive styles may increasingly face scrutiny under disability accommodation laws, particularly as neurodiversity awareness increases.

These talent implications have significant financial consequences. According to research by Harter and Adkins (2017), replacing a professional employee typically costs 100-150% of annual salary, making the retention impact of appropriate environments a major financial consideration.

Health and Wellbeing Economics

Workplace design also significantly impacts health outcomes with economic implications:

• Stress-related illness: Studies by Thayer et al. (2010) found that employees in open-plan offices show 32% higher incidence of stress-related health complaints compared to those in private or shared offices, with associated increases in healthcare utilization and absenteeism.
• Cognitive fatigue effects: Research by Kaplan (2001) demonstrates that sustained work in environments without appropriate restoration opportunities increases burnout risk by 21-28%, with associated increases in turnover and performance degradation.
• Sleep quality impact: Studies by Vischer (2007) show that sustained exposure to environmentally stressful workplaces correlates with decreased sleep quality through rumination effects, creating a negative feedback loop of diminished cognitive capacity.
• Mental health outcomes: Research by Laurence et al. (2013) found that employees without access to appropriate privacy at work report 27% higher anxiety scores and 18% higher depression indicators than those with privacy options.
• Physiological stress markers: Studies by Evans and Johnson (2000) measuring epinephrine levels demonstrate that even “adapted” workers in open environments show elevated physiological stress markers despite subjective adaptation, indicating hidden health impacts.

These health effects translate directly to business costs. Research by Steelcase (2019) estimates that the health-related costs of inappropriate work environments average $2,100-$4,300 per knowledge worker annually when accounting for absenteeism, presenteeism, and healthcare utilization.

Frameworks for Understanding and Designing Optimal Environments

The Cognitive-Environment Fit Matrix

Research supports conceptualising workplace needs along two key dimensions: cognitive activity type and processing style preference, creating a matrix that helps identify appropriate environmental conditions:

This matrix helps organizations recognise that no single environment can optimally support all cognitive activities and styles—a fundamental flaw in standardised open-plan approaches. Research by Wohlers and Hertel (2017) demonstrates that alignment between cognitive tasks, individual processing styles, and environmental conditions improves performance by 17-26% compared to misaligned situations.

The Environmental Control Continuum

Research by Lee and Brand (2010) supports conceptualising environmental control across several dimensions that significantly impact cognitive functioning:

Low Control Environment ←→ High Control Environment

• Fixed furniture and layout … Reconfigurable elements
• Predetermined settings … User-adjustable features
• Standardized conditions … Personalization options
• Protocol rigidity … Behavioural flexibility
• Technology constraints … Technology choice
• Territorial ambiguity … Clear boundaries
• Mandatory presence … Location flexibility
• Ambient exposure … Stimulation control

This continuum helps explain why ostensibly similar physical environments can produce dramatically different cognitive outcomes depending on the degree of control afforded to occupants. Studies by Veitch and Newsham (2000) demonstrate that each additional dimension of environmental control corresponds to an 8-12% increase in cognitive performance and satisfaction, even when objective conditions remain similar.

The Sensory Management Framework

Research by Augustin and Fell (2015) identifies specific sensory dimensions that require management for optimal cognitive performance:

Acoustic Management Requirements:

• Background noise levels (optimal range: 38-48 dB for focused work)
• Speech privacy (minimum Speech Privacy Index of 0.95 for concentration)
• Sound masking characteristics (frequency range 100-8000 Hz)
• Reverberation control (optimal RT60: 0.4-0.6 seconds)
• Acoustic zoning (minimum 15 dB difference between zones)

Visual Environment Elements:

• Movement management (maximum 10% of visual field with movement)
• View content (natural elements showing demonstrable benefits)
• Visual complexity (moderate complexity optimal vs. chaotic or sterile)
• Lighting characteristics (task-appropriate illumination and spectrum)
• Privacy gradients (visual access control options)

Spatial Characteristics:

• Proxemic comfort (appropriate interpersonal distances)
• Territorial clarity (clear boundary definition)
• Pathway management (traffic patterns that minimize disruption)
• Posture options (appropriate settings for different task modes)
• Density considerations (minimum 100-120 sq ft per person for knowledge work)

Ambient Conditions:

• Temperature control (individual adjustment range of ±3-4°F)
• Air quality management (CO2 levels below 800 ppm)
• Humidity optimization (optimal range: 30-60%)
• Scent management (neutral or nature-based subtle scents)
• Chronobiological support (lighting that supports circadian rhythms)

This multisensory framework recognizes that cognitive performance depends on the integrated management of multiple environmental dimensions rather than optimization of single variables in isolation.

The Activity-Based Working 2.0 Model

Research by Appel-Meulenbroek et al. (2022) supports an evolved understanding of activity-based working that incorporates cognitive diversity considerations:

• Beyond activity to cognition: Traditional activity-based working focuses on task categories, while the evolved model addresses underlying cognitive processes and styles.
• Setting diversity principle: Environments should provide a minimum 1:5 ratio of distinct setting types to employees, with each setting optimized for specific cognitive modes rather than generic activities.
• Cognitive ergonomics: Beyond physical ergonomics, environments should support cognitive workflow through transition spaces, cognitive tools, and setting-appropriate technology.
• Protocol clarity: Successful cognitively-diverse environments require explicit protocols about setting usage, boundaries, and interaction norms that prevent cognitive interference.
• Transition support: The model emphasizes transition zones and practices that support cognitive mode-switching between different types of work settings.

Research by Leesman (2022) demonstrates that organizations implementing this evolved activity-based approach show 24% higher cognitive performance scores and 31% greater employee satisfaction compared to traditional open plans or first-generation activity-based implementations.

Case Studies: Cognitive Environment Excellence in Action

Technology Sector Implementation

A global technology company implemented a comprehensive cognitive diversity approach to workplace design:

• Cognitive zoning strategy: Rather than standard neighborhoods, the organization created distinct cognitive zones—deep focus areas with high acoustic and visual protection, collaborative areas with appropriate tools and containment, and transitional spaces supporting cognitive mode switching.
• Personal control systems: Implemented an environmental control app allowing individuals to locate appropriate settings based on their current cognitive needs, check real-time conditions (noise levels, occupancy, light levels), and reserve spaces matching their cognitive preferences.
• Sensory management approach: Developed comprehensive acoustic strategy with sound masking, absorption, and containment creating a 30 dB gradient between focus and collaborative zones, plus visual management tactics minimizing unnecessary disruption.

Results: The company reported 34% reduction in cognitive complaints, 28% improvement in self-reported productivity, and significant improvements in talent retention particularly among technical roles requiring deep concentration (Microsoft, 2021).

Professional Services Transformation

A consulting organization redesigned their office environment around cognitive performance principles:

• “Focus first” prioritization: Inverted the typical approach by designing primarily for concentrated work with exceptional acoustic and visual protection, supplemented by well-contained collaborative settings, recognizing that focus is their scarcest cognitive resource.
• Client co-creation spaces: Developed specialized environments supporting client collaboration with appropriate tools, technology integration, and sensory management, spatially separated from internal work areas.
• Cognitive diversity support: Created explicit “cognitive profiles” describing different environmental needs and providing corresponding settings, coupled with awareness training that normalized diverse sensory preferences.

Results: The firm documented 26% improvement in work quality measures, 31% increase in employee-reported ability to perform complex cognitive tasks, and 38% enhancement in client ratings of innovation quality (Deloitte, 2020).

Financial Services Implementation

A financial institution implemented a cognitive-based environment design:

• Analysis suite development: Created specialized environments supporting financial analysis with exceptional acoustic protection, ergonomic optimization for long-duration focus, and technology integration supporting complex information processing.
• Temporal zoning strategy: Implemented time-based protocols for different spaces, with mornings prioritized for deep cognitive work (with corresponding expectations about interruption and noise levels) and afternoons designated for collaborative activities.
• Recovery space integration: Developed dedicated cognitive restoration spaces incorporating nature elements, sensory calming, and psychological separation from work environments, explicitly positioned as performance support rather than perks.

Results: The organization achieved 23% improvement in analysis accuracy measures, 29% reduction in reported cognitive fatigue, and significant gains in talent attraction specifically citing the cognitive-supportive environment as a differentiating factor (Morgan Stanley, 2021).

Conclusion: From Open Plan to Cognitive Ecology

The evidence presented in this paper demonstrates that effective workplace design must move beyond the false binary of “open versus closed” to address the fundamental question of cognitive support. Neither fully open nor fully enclosed environments represent the answer; rather, organizations need to create diverse “cognitive ecologies” that support the full spectrum of thinking styles and work modes essential for knowledge work effectiveness.

The most forward-thinking organizations now recognize that cognitive diversity—including different sensory processing needs, attention management styles, social energy patterns, and environmental preferences—represents a valuable organizational asset rather than a problem to be solved through standardization. These organizations design environments offering genuine choice, control, and appropriate conditions for different cognitive activities rather than generic compromises that fail to fully support any mode of work.

By implementing the evidence-based approaches outlined in this paper, organizations can transform their workplaces from cognitive battlegrounds to genuine performance enablers. This approach requires moving beyond simplistic design ideologies toward research-grounded understanding of human cognitive functioning in all its diversity. In a business landscape where competitive advantage increasingly derives from complex cognitive work—analysis, creativity, strategy, and innovation—organizations that master cognitive environment design gain a significant edge: not by forcing adaptation to inappropriate conditions but by creating environments where diverse cognitive styles can perform at their natural best.
