The Workplace Designed for Someone Else

Open plan offices became the dominant workplace design around the same time that neuroscience was quietly documenting everything wrong with them. The logic was straightforward: remove barriers, increase collaboration, share ideas. The reality for tens of millions of workers — particularly those with ADHD — is a daily exposure to conditions that are functionally hostile to how their brains process information. This is not a complaint. It is a description of a measurable mismatch between architectural choice and neurological need.

What Open Plans Actually Do to Attention

The human brain does not filter background noise passively. It actively suppresses irrelevant input, which requires executive resources. For neurotypical workers, this suppression is largely automatic. For people with ADHD, the suppression mechanism is impaired. Every nearby conversation, keyboard sound, and passing footstep competes on roughly equal footing with the task at hand. The result is not just distraction — it is cognitive depletion. The ADHD brain working in an open plan office is doing double duty: trying to complete a task while also running an explicit, effortful suppression process that other brains run for free. By midday, the executive reserves that make sustained work possible are significantly diminished. A study from the University of Sydney found that workers in open plan offices reported significantly higher levels of noise dissatisfaction, concentration difficulty, and privacy concerns than those in private offices or shared rooms. The study controlled for job type and found the effects were consistent across industries.

The Specific Problems

Hot-desking — the practice of assigning no fixed workspace so that employees find a new seat each day — adds a second layer of difficulty. For someone with ADHD, environmental consistency is a compensatory resource. Knowing where things are, having a predictable arrangement of monitors and reference materials, and building associative memory between physical location and task type all reduce the cognitive overhead of getting started. Hot-desking eliminates those anchors. Visual openness presents its own challenge. The ADHD brain is drawn toward novelty and movement. An open floor plan provides a constant supply of both. A colleague standing up, someone laughing three rows over, a delivery arriving at the front desk — each is a small but real attentional pull that requires active redirection.

Accommodation Is Not a Favor

The legal framing around workplace accommodation for ADHD varies by country, but the underlying logic is consistent: if a condition substantially limits a major life activity — and concentration is a major life activity — then reasonable adjustments are appropriate. In practice, people with ADHD often do not request accommodation because they do not want to disclose a diagnosis, do not believe accommodation will be granted, or have internalized the cultural narrative that struggling with focus is a character issue rather than a neurological one. The result is that workers manage quietly, produce less than they are capable of, and eventually leave or are let go for performance problems that a different work environment might have prevented. Research from the Canadian ADHD Resource Alliance found that adults with ADHD who had access to even one workplace accommodation — noise-canceling headphones, a private desk, or flexible hours — reported substantially higher job satisfaction and significantly lower rates of job loss than those without any accommodation.

The Tangent About Remote Work

The pandemic produced an accidental natural experiment. Adults with ADHD, when surveyed in 2021 and 2022, reported disproportionately high levels of improved work performance during remote work periods. This is counterintuitive only if you assume that the problem is discipline. If you understand that the problem is environment, it makes perfect sense: working from a controlled home environment, in silence, with self-managed breaks and no visual noise from colleagues, removed the primary obstacle for many ADHD workers. The push to return to office has reversed many of those gains.

What Managers Can Actually Do

None of this requires rebuilding the physical office. It requires treating workspace as a variable rather than a fixed constant. For workers with ADHD, access to quiet rooms for focused work, flexibility in where they sit, tolerance for headphone use, and meeting times that do not fragment the workday into unusable chunks can produce substantial improvements in output without costing the employer anything significant. The cost of not doing it — turnover, underperformance, and the slow exit of capable people — is considerably higher.
