Open Office vs Cabins: How to Decide

Almost every office brief in India begins with the same argument. The owner wants a cabin — often several — because that is how an Indian office has traditionally signalled seniority and how confidential conversations have always been held. The younger team wants an open floor, because that is what modern offices look like and because it is easier to work together. The landlord's floor plate, the rent and the budget sit quietly in the background and usually decide the matter without anyone saying so.

The decision deserves more care than that. An office that is all cabins uses twice the floor area per person, blocks daylight from most of its staff and costs more to build and to cool; an office that is all open plan can be noisy, distracting and impossible for confidential work. The right answer depends on what the people in the office actually do all day — how much of their work needs concentration, how much needs collaboration, how many calls they take, how often clients visit and how much of what they discuss must stay private.

This guide sets out the options, the numbers behind them, and a method for deciding. It is written for business owners, managers and young designers planning offices from a 500 sq ft practice to a 10,000 sq ft floor, and it draws on the space standards used in Aaditya Interior's office design and workstation guides.

A short history of cabins and open floors

The private office is old: clerks, managers and partners in nineteenth- and early-twentieth-century firms worked in rooms off corridors, with typing pools and general offices in larger halls. In India, the traditional trading office — the gaddi, with the proprietor seated on a raised mattress and staff around him — was open in form but hierarchical in arrangement; as offices moved into modern buildings, that hierarchy turned into the owner's cabin, which remains a near-universal feature of Indian small and medium businesses.

The modern open office has two well-documented roots. In Germany in the late 1950s, the Quickborner team developed Bürolandschaft, or office landscape — desks arranged in organic groups according to workflow, with screens and plants rather than walls. In the United States in the 1960s, Robert Propst designed the Action Office system for Herman Miller, intended to give workers flexible, partly enclosed workspaces; in later, cheaper copies it became the cubicle. From the 1990s, benching — long, shared desks without high screens — spread with laptops and IT companies, and India's technology parks adopted it at scale. More recently, activity-based working and post-2020 hybrid attendance have shifted the question again: from where each person sits to what range of spaces a team needs.

The four layouts, with numbers

It helps to strip the argument down to floor area. Every layout has a typical density — the carpet area per person once desks, aisles, meeting rooms, reception, pantry and storage are included. The figures below are consistent with the benchmarks in Aaditya Interior's office design guide; they are planning ranges, not rules.

The numbers explain the cost of cabins more clearly than any opinion. On the same 2,100 sq ft floor, an all-cabin plan seats about 14 people, an open cluster plan about 26 and a hybrid about 20. If rent and maintenance in a commercial building cost, say, ₹100 per sq ft per month, the space cost per seat is roughly ₹15,000 a month in the all-cabin plan and about ₹8,000 in the open plan — before any fit-out. That gap has to be justified by the work the cabins make possible.

What the work needs: a decision matrix

The most reliable way to decide is to look at the work, not at the organisation chart. For each role in the office, ask five questions. How much of the day is spent on concentrated solo work? How much on collaboration with people at nearby desks? How many phone and video calls, and are they confidential? How often do clients or outsiders visit, and what do they need to see or hear? And are there documents, cash or data that must physically be kept secure? The answers point clearly towards open or enclosed space, and they often show that what a role needs is not a cabin but access to an enclosed room when the need arises.

Working through the matrix usually produces a pattern. A chartered accountant's practice ends up with cabins for partners and a meeting room for clients, but an open floor for articles and accounts staff. A design studio needs an open studio for its team, a quiet review table and one or two rooms for client presentations. An IT team needs mostly open clusters, generous phone booths and two or three small meeting rooms. Very few businesses genuinely need everyone enclosed, and very few can work well with no enclosed space at all.

The percentages in this table are Aaditya Interior's working guidance from planning offices of these types; they are a starting point for the brief, not a standard. The useful habit is to count enclosed rooms by function — focus, call, meeting, confidential — rather than by job title.

Standard sizes: cabins, desks and rooms

Once the mix is decided, standard dimensions turn it into a plan. The sizes below match Aaditya Interior's office design and workstation dimension guides: a 1200 × 600 mm desk at 750 mm height, a 900 mm chair zone behind it, main aisles of 1200 mm, and cabins sized around the desk, two visitor chairs and storage.

Acoustics: the real problem with open offices

Complaints about open offices are mostly complaints about sound. Speech is the most distracting noise there is, because the brain cannot ignore words it can understand. A conversation two desks away is far more disruptive than a louder air-conditioner hum. The problem is worst in hard-surfaced Indian offices — vitrified tile floors, gypsum ceilings, glass partitions, painted walls — where sound reflects instead of being absorbed.

The cure has three parts, often summarised in acoustic practice as absorb, block and cover. Absorb with an acoustic ceiling (mineral-fibre tiles or acoustic panels), carpet tiles or vinyl, and fabric or felt panels on walls. Block with screens between desks and by keeping noisy functions — pantry, printers, reception — away from focus areas. Cover with steady background sound from the air-conditioning or, in larger offices, a sound-masking system. An open office designed with all three is a very different place from one that simply removes walls.

Cabins have their own acoustic trap. A partition that stops at the false ceiling leaves the space above open, and sound travels over it from cabin to cabin and from cabin to open floor. A cabin is only private if its partition runs to the slab, or if a sound barrier is built in the ceiling void above the partition line, and if the door seals. Glass fronts also matter: a single glazed panel is much less private than a well-built gypsum wall, and confidential rooms need either double glazing or a solid wall with only a vision panel.

Partition prices are indicative October 2026 ranges, per square foot of partition face, including framing, glass or boards and basic finishing; doors, hardware, films and blinds are extra. They vary widely with system, height and city, and should always be confirmed with a local vendor.

Daylight and air: why cabins should not own the windows

The second big difference between layouts is daylight. In a typical office, useful daylight from side windows reaches roughly two to two-and-a-half times the window head height into the room — a common rule of thumb in daylighting practice. With a window head at 2700 mm, that is about 5.5–6.5 m. When cabins line the window wall, they consume most of that zone for a handful of people and leave everyone else under artificial light all day. Placing cabins on the inner side of the floor, with glass fronts, reverses this: the open floor gets the window, the cabins borrow light through their glass and the floor plate feels larger.

Air-conditioning follows the same logic. An open floor can be served by a few large zones; every cabin needs its own diffuser and return path, and ideally its own control, because a closed room with one or two people and a sunny window overheats quickly while the open floor stays cool. Cabins also need fresh air: a sealed room with three or four people in a long meeting builds up carbon dioxide fast, which NBC 2016 Part 8 addresses through ventilation requirements. Each enclosed room therefore adds cost and complexity to the HVAC design, which is a reason to have fewer, well-used rooms rather than many.

What each option costs to build

Cabins cost more per square foot of office because they add partitions, doors, more lighting circuits, more AC diffusers and more glazing, and because each room needs its own finishes. Open plan spends more on workstations per square foot simply because there are more of them, and should spend more on acoustic ceilings and flooring. Using the national office bands from Aaditya Interior's office cost guide, the two approaches typically land as shown below. Rates are indicative October 2026 figures per sq ft of office carpet area, excluding AC equipment, IT hardware and GST.

The cost of the fit-out is usually smaller than the cost of the space over a lease. A cabin-heavy plan that houses 14 people on a floor where an open plan houses 26 carries its higher rent per person every month for the whole lease. That is why the decision should start with the work matrix, then the floor area, and only then the fit-out budget.

Planning the hybrid office

For most Indian businesses the answer is a hybrid, and the quality of a hybrid depends on a few planning moves. First, keep the window wall for the open floor and put enclosed rooms on the inner side, near the core, with glass fronts and a frosted band at eye level for privacy. Second, give enclosed rooms by function rather than by rank: a ratio of roughly one phone booth per 8–12 open seats, one small meeting room per 10–15 people and a quiet zone or focus room for heads-down work. Third, separate noisy and quiet zones — reception, pantry and printers on one side, focus areas on the other — with storage walls or meeting rooms between them.

Fourth, design for change. Teams grow and shrink faster than leases end. Benching systems, demountable glass partitions, raised or surface power and data tracks and a grid ceiling that does not care where the walls go make it cheap to turn two cabins into a meeting room or a meeting room into four desks. Finally, write down the rules: who can book which room, whether cabins are used for client calls by others when the owner is out, and where people take personal calls. Hybrid offices that work have clear etiquette; those that fail usually have the right rooms but no agreement on how to use them.

Where office layouts are heading

The direction across Indian cities is towards fewer personal cabins and more shared enclosed rooms. Partial attendance means a fixed desk for everyone is often wasted, while the number of video calls has made phone booths and small meeting rooms the most demanded spaces in many offices. Leaders increasingly sit on the open floor with access to a bookable room, and the traditional owner's cabin, where it remains, is smaller, glass-fronted and doubles as a meeting space. Acoustic products — felt panels, ceiling baffles, booths — have become standard items rather than luxuries. At the same time, confidentiality requirements in legal, financial and health work, and data-protection obligations generally, keep a firm place for genuinely private rooms. The future office is neither open nor cellular; it is a range of settings, chosen for the work.

Rules for deciding between open plan and cabins

• Start with the work, not the hierarchy: list focus, collaboration, call, confidentiality and client needs for each role.
• Count enclosed rooms by function — booths, focus rooms, meeting rooms, cabins — rather than by job title.
• Keep the window wall for the open floor; place cabins and meeting rooms on the inner side with glass fronts.
• Budget by space as well as fit-out: compare rent per seat at 80–110 sq ft (open) and 130–200 sq ft (cabins).
• Make open floors acoustically treated from day one: absorbent ceiling, soft flooring and wall panels.
• Take confidential room partitions to the slab or close the ceiling void, and seal the doors.
• Provide about one phone booth per 8–12 open seats and one small meeting room per 10–15 people.
• Choose demountable partitions, benching and flexible power and data so the plan can change with the team.

Frequently asked questions

Is an open office better than cabins?

Neither is better in general. Open offices use space more efficiently, share daylight and make collaboration easy, but they need acoustic treatment and quiet rooms. Cabins give privacy and focus but use about twice the area per person and cost more to build and cool. Most offices need a mix chosen by the type of work.

What is the standard size of an office cabin in India?

A compact cabin is about 2400 × 3000 mm, a typical manager cabin 3000 × 3000 to 3000 × 3600 mm, and a director's cabin 3600 × 4200 mm or more. The size follows from a desk of 1500 × 750 mm, two visitor chairs, a credenza and comfortable circulation.

How much space is needed per person in an open office?

Typical open or cluster offices plan about 80–110 sq ft of carpet area per person, including desks, aisles, meeting rooms, pantry and storage. Dense operations can go to 60–75 sq ft; generous layouts with many shared rooms go to 110–130 sq ft.

Are glass cabins soundproof?

No. A single toughened glass partition gives limited speech privacy, and sound also travels over partitions through the ceiling void and around doors. For confidential rooms, use double glazing or an insulated gypsum wall taken to the slab, with sealed doors.

How many meeting rooms does an office need?

As a starting point, plan about one small meeting room for every 10–15 people and one phone booth for every 8–12 open seats, then adjust for how many calls and client meetings the team actually has. Offices with heavy video-call use usually need more small rooms and booths, not more large boardrooms.
