Open Plan, Cellular & In Between

Picture the two pure extremes. At one end is the fully open plan: a single large room, rows or clusters of desks, no internal walls, everyone in sight of everyone. At the other is the fully cellular office: a corridor of closed rooms, one or a few people behind each door, privacy and quiet by default. Every real office is a blend of these, but it helps to understand why each pure type was believed in, because the beliefs still drive decisions today.

The open plan was, and is, championed for good reasons. It is cheaper and denser - more people per square metre, less spent on walls and doors - which matters enormously to the people paying for space. It is flexible: with no fixed walls you can rearrange teams, add desks, reconfigure as the organisation changes, which suits fast-moving companies. It spreads daylight and views across the floor rather than trapping them behind private offices. And it carries a powerful cultural promise: that openness breeds communication, collaboration, equality and a flat, transparent culture - no corner offices, everyone visible, ideas flowing freely. That promise, as much as the cost saving, is why so many organisations, from Silicon Valley to Indian start-ups and GCCs, embraced it.

The cellular office has its own real virtues, which the open-plan enthusiasm often dismissed too quickly. It offers quiet, privacy and control: a door you can close, freedom from the constant low noise and visual movement of an open floor, the ability to concentrate, take a confidential call or have a private conversation. It suits work that is focused, sensitive or confidential - legal, financial, HR, deep individual knowledge work. And it carries its own cultural signals, of status, seniority and respect. Its costs are the mirror of the open plan's virtues: it is expensive and low-density, it can isolate people and reduce the casual contact that builds teams, and its fixed walls make it rigid and hard to change. Hold both honest pictures in mind: each extreme buys something real and pays for it with something equally real.

Here is where honesty matters most, because the debate is soaked in selective citation. The careful research on open-plan offices does not support the simple story that openness reliably boosts collaboration and productivity. What it broadly and repeatedly finds instead is that open-plan layouts, compared with more enclosed ones, tend to increase noise, interruption and distraction, reduce perceived privacy, and are often associated with lower satisfaction and, in some studies, more stress and even more sick leave. The very thing that makes the open plan cheap - packing people together without barriers - is also what makes it hard to concentrate in.

The most striking and widely discussed finding goes further and undercuts the open plan's central promise directly. A prominent study of organisations that removed walls and moved to open plan found that, contrary to the expectation that openness would increase face-to-face interaction, face-to-face contact actually fell substantially, while electronic messaging rose. The interpretation is intuitive once stated: when everyone is exposed and audible, people retreat - they put on headphones, avoid conversations that the whole floor would overhear, and message the person two desks away rather than speak. Openness, pushed too far, can produce the opposite of the connection it promised.

But honesty cuts both ways, and this is not a vindication of the cellular office either. The research does not say walls make people productive and collaborative; isolation has real costs too, and much good work genuinely benefits from easy contact and shared awareness. Nor are the studies unanimous or free of the difficulty that 'open plan' covers wildly different realities - a cramped call-centre floor and a spacious, well-zoned studio are both 'open plan' and nothing alike. The sober reading is this: pure open plan, imposed as a blanket solution, reliably damages focus and privacy and does not reliably deliver the collaboration it promises; and pure cellular sacrifices contact, cost and flexibility. Which is precisely why the answer lies between them, and why the open-plan backlash should lead not to a rush back to walls but to smarter, more varied design.

Once you accept that neither extreme wins, the interesting territory opens up: the spectrum between them, where almost every good modern office actually lives. The design question stops being the binary 'open or cellular?' and becomes a set of richer ones: how much of this floor should be open, how much enclosed; what kinds of enclosure (a closed meeting room, a phone booth, a team room, a focus pod); where the boundaries fall; and how to get the openness's contact and flexibility without its noise and exposure.

Several well-worn points on the spectrum are worth knowing. The mostly-open floor with support rooms keeps open desks for the bulk of people but adds enclosed focus rooms, phone booths and meeting rooms so that privacy and quiet are available on demand - this is the dominant contemporary model and the foundation of the next two lessons. Team or group offices give a whole team a shared enclosed room - more private than open plan, more collaborative than individual cells - a middle form common in many European and professional-services settings. Zoned open plan keeps the floor open but breaks it acoustically and visually into smaller neighbourhoods with lower density, planting, screens and varied ceilings, so it never becomes one undifferentiated noisy hall. And activity-based layouts abandon the idea of one owned desk altogether in favour of a variety of settings people choose from by task - the subject of Module 7.

The craft, then, is calibration, not ideology. A law firm or a therapy practice, full of confidential and deeply focused work, sits far toward the enclosed end; a design studio thriving on constant interaction sits more open but still needs quiet retreats; a typical mixed organisation lands in the broad middle - a well-zoned open floor generously equipped with enclosed settings for the work that open plan does badly. The mistake to avoid is the blanket decision: imposing a single layout on everyone because it is cheap, or fashionable, or because the last office had walls. Read the work, read the people, and design the specific mix they need - which is exactly what the palette of settings in the next lesson lets you build.

So how do you actually choose where on the spectrum a given office, or a given part of it, should sit? Start from the work and the people, not from cost or fashion. The more focused, confidential or sensitive the work, the more enclosure it needs; the more collaborative, fast-moving and contact-dependent, the more openness serves it - but always with quiet retreats available, because even the most collaborative team has people who need to concentrate and calls that need privacy. Different teams on the same floor legitimately sit at different points, which is why a single blanket layout so often fails someone. Culture matters too: the signal a layout sends - flat and open, or hierarchical and private - should fit the organisation honestly rather than impose a culture it does not have.

Two practical cautions temper any enthusiasm for the open end. First, openness without acoustic and visual design is the trap that created the backlash: an open floor only works if noise, speech privacy and interruption are actively managed with zoning, sound absorption, masking, screens and enough enclosed settings to absorb the work open plan does badly. That acoustic reconciliation is important enough to get its own lesson in Module 4; for now, the rule is simple - never specify open plan without designing how focus and privacy will survive in it.

Second, as ever in this course, defer the binding specifics. How many enclosed rooms you can fit, how dense the open floor can be, how far people sit from an exit and from daylight - these run straight into fire egress and occupant-load limits, accessibility clearances, ventilation and daylight provisions that are set by the current codes and verified with the fire, services and accessibility specialists, not decided by the layout debate. And the density and sharing figures that tempt people toward the open, cheap end are illustrative benchmarks to calibrate with real occupancy data, not rules. Choose the mix from the work and the people, manage its acoustics deliberately, and let the codes and specialists set the binding numbers.
