Every term you will meet in a brief, a tender or a fit-out proposal, defined in plain English with the context that tells you why it matters.
Written for business owners and facilities teams in Bangalore and across India who are commissioning a corporate fit-out, design and build or office interior project and want to read a quote without a translator.
Part of the full corporate fit-out and office interior design guide.
Quick answer
The corporate fit-out vocabulary matters because it is how a brief, a quote and a tender are written. When you can tell a Cat A shell from a Cat B fit-out, read a BOQ line, and ask about the defects liability period, you compare proposals on real terms, spot what a price leaves out, and hold a firm to the right scope. This glossary defines the terms so you negotiate from knowledge, not guesswork.
How a fit-out is bought and who carries which risk. These terms decide accountability before a single wall goes up.
The work of turning a bare or stripped commercial space into a finished, working office, clinic, shop or restaurant: partitions, ceilings, flooring, services, joinery, furniture and finishes. It sits at the heart of every project term on this page. Why it matters: the word "fit-out" alone says nothing about scope, so when a firm quotes a corporate fit-out, ask exactly which trades, finishes and furniture the number covers and which are excluded.
A delivery model where one firm owns both the design and the construction under a single contract, giving the client one point of accountability instead of a separate designer and builder. It usually runs faster because design and procurement overlap. Why it matters: it removes the gap where a designer and a contractor blame each other. What to ask a firm: do you carry the design in house or sub-contract it, and who signs off the final cost.
An arrangement where you hand over a brief and a budget and receive a finished, ready-to-occupy space, with one firm handling design, approvals, procurement, construction and handover end to end. Why it matters: it is the lowest-effort route for a client with no in-house project team, but the single price can hide trade-offs. What to ask: what brand and grade of materials sit behind the headline rate, and what counts as a variation you will be charged extra for.
The same idea as turnkey interiors applied specifically to the fit-out works: a finished, ready-to-occupy space delivered end to end by one firm under one contract, so the client effectively turns a key and moves in. Why it matters: it bundles design and construction risk into one quote. What to ask a firm: is furniture, AV and IT cabling inside the turnkey number, and is the handover date a contractual commitment or an estimate.
The physical works that finish a space: partitions, ceilings, services, flooring, joinery and furniture. It is the construction half of an interior project, as opposed to the design and drawings. Why it matters: most fit-out budget is spent here, so this is where value engineering and quality control bite hardest. What to ask: who is the actual site contractor doing the interior fit-out, and have they delivered a similar size and use of space before.
The landlord's base finish handed to a tenant: raised access floor, suspended ceiling, basic mechanical and electrical services, painted walls and finished common areas, but no layout, branding or furniture. Why it matters: it sets the starting line for your own works and changes how much you must spend. What to ask: is the unit being offered as a bare shell, a Cat A space, or a managed fit-out, because that single answer can shift your budget by a wide margin per sq ft.
The tenant's layer on top of Cat A: the actual layout, cabins, meeting rooms, reception, branding, lighting design, joinery and furniture that make the space yours. Why it matters: this is the work most owners picture when they say "fit-out" and where the brand and the way you work get built in. What to ask a firm: does the quote cover Cat B in full, including furniture and AV, or only the construction trades.
An informal extension of Cat B used for further tenant customisation, often a later phase or a deeper level of bespoke work beyond the standard tenant layer. The term is used loosely in the India market, so it can mean different things to different firms. Why it matters: it can quietly expand scope. What to ask: when a quote mentions Cat C, get a written line-by-line list of exactly what it adds over Cat B.
The phases, paperwork and sign-offs that move a project from brief to a handed-over, working space.
Reworking an occupied or recently vacated office rather than fitting out a fresh shell: new layout, finishes, services or furniture inside walls that already exist. Why it matters: refurbishment carries constraints a new fit-out does not, such as working around live operations, older services and the existing structure. What to ask a firm: can the office refurbishment run in phases or out of hours so the business keeps trading while work goes on.
The general term for upgrading an existing space instead of fitting out a fresh shell, whether an office, a shop or a clinic. A refit may be light, new paint, carpet and furniture, or deep, stripping back to the slab. Why it matters: condition surveys, asbestos or old wiring and structural limits all affect cost and timeline. What to ask: has the firm surveyed what is behind the walls before pricing the refurbishment.
The bill of quantities: the line-by-line priced schedule of a project, listing every item, its quantity, rate and total, from partition runs to light fittings. Why it matters: the BOQ is the document you actually compare between firms, and a vague one hides cost. What to ask a firm: give me an itemised BOQ rather than a lump sum, so I can see the rate per item and judge where the money goes and what is provisional.
Reducing the cost of a project by swapping materials, details or methods for cheaper equivalents without gutting the design intent, usually done when a first BOQ comes in over budget. Why it matters: done well it protects the look while trimming cost; done badly it quietly downgrades quality. What to ask a firm: when you value engineer, show me exactly what changes and what I lose, so I approve each swap rather than discover it on handover.
The structured walk-through near the end of a project that lists every defect, unfinished item and blemish, the snag list, that the firm must fix before the space is signed off. Why it matters: snagging is your leverage to get the job finished to standard. What to ask a firm: who attends the snagging walk-through, how is the snag list tracked, and how long do you have to clear it before handover is accepted.
Testing and formally signing off the building systems, power, HVAC and air conditioning, fire detection and suppression, data and access control, so they work as designed before anyone occupies the space. Why it matters: a space can look finished while its systems are not safe or certified to run. What to ask a firm: which third-party tests and certificates come with commissioning, and are they handed to me as part of the closeout documents.
The window after handover, usually six months to a year, during which the firm returns to fix failures and defects that show up in normal use, at no extra cost. Why it matters: it is your safety net once the team has left site. What to ask a firm: how long is the defects liability period, what does it cover and exclude, and is any payment retained until it ends so there is an incentive to come back.
How square footage becomes desks, cabins and zones, and the planning decisions behind a working floor.
Working out how many people, cabins, meeting rooms and support zones fit into a floor and where each goes, before any design styling begins. Why it matters: it sets the headcount the office can hold and how it will feel to work in, and a poor plan is expensive to undo once built. What to ask a firm: how many seats can this floor take comfortably, and can you show two or three space-planning options before we commit to a layout.
A single desk position, the basic counting unit of an open-plan office, including the desk, chair, power and data point and any screen between neighbours. Why it matters: cost and capacity are often quoted per workstation, so it is the number you budget and plan headcount against. What to ask a firm: what is the all-in cost per workstation including furniture, power and data, and how much floor area does each one need.
An enclosed room for a manager, director or private work, walled off from the open floor for confidentiality and quiet. Why it matters: cabins use far more floor area per person than open desks and shape the open-plan versus cabin balance. What to ask a firm: how many cabins do we really need versus bookable meeting rooms, given that every cabin removes several workstations worth of space from the floor.
The wall behind a cabin desk, the surface a visitor faces across the table, which usually carries the brand, the logo, a finish or a feature treatment. Why it matters: it is the most photographed and most brand-defining surface in a private office. What to ask a firm: what finish do you propose for the office cabin wall, and can we see a 3D visual of how the brand sits on it before it is built.
A glass or solid divider that separates areas, gives focus and contains sound without permanently sealing people in, ranging from full-height glazed walls to low desk screens. Why it matters: partitions decide how open or private the floor feels and carry acoustic and fire ratings that affect cost. What to ask a firm: are the office partitions demountable so we can reconfigure later, and what acoustic rating do the glazed ones offer.
The front-of-house area that sets a visitor's first impression: the reception desk, waiting seating, branding wall and the route into the office. Why it matters: it is the highest-visibility space in the fit-out and where brand spend earns the most return. What to ask a firm: how do you make the reception and lobby reflect our brand within budget, and what lead time does a bespoke reception desk add to the programme.
A shared, largely unpartitioned floor of workstations where teams sit together in the open rather than in separate rooms. Why it matters: it fits more people per sq ft and aids collaboration, but raises noise and privacy issues that need design answers. What to ask a firm: how will you handle acoustics, focus space and meeting demand in an open-plan office so the saving on cabins does not cost us in concentration.
The split between shared open desks and enclosed cabins in a layout, often expressed as a percentage, that captures how open or cellular an office is. Why it matters: this single ratio drives capacity, cost and culture more than almost any other layout decision. What to ask a firm: what open-plan vs cabin ratio do you recommend for our headcount and the way our teams actually work, and how does changing it move the seat count and the budget.
Matching space, layout and settings to how a team really works: how many people are in on a given day, how much focus versus collaboration they need, and which settings, desks, rooms, quiet zones, support that. Why it matters: it stops you building for a pattern of work you no longer follow, such as full daily attendance. What to ask a firm: do you start with a workplace strategy and occupancy study before drawing a layout, or do you jump straight to a floor plan.
Flexible space shared by members from different companies, designed to flex as they come and go, with hot desks, private cabins, meeting rooms and shared amenities under one operator. Why it matters: it has its own fit-out logic built around churn, branding and member experience rather than one tenant's needs. What to ask a firm: have you fitted out coworking or shared workspace before, and how do you design for constant reconfiguration and heavy daily use.
A multi-unit commercial building that houses offices, shops, clinics or showrooms for several occupiers, with shared services, parking and common areas. Why it matters: fitting out a unit inside a commercial complex means working within the building's rules, base services and approval process, not just your own four walls. What to ask a firm: what landlord and building-management approvals does a fit-out in this commercial complex need, and how long do they take.
The design discipline, the bespoke and standard elements, and the visuals that show a space before it is built.
Interior design for any space a business trades from, offices, clinics, shops, showrooms, restaurants and coworking spaces, balancing brand, budget, the way the business operates and the rules of the sector. It covers space planning, the concept, materials, lighting, acoustics and furniture. Why it matters: it is the brain of the project that the fit-out then builds. What to ask a firm: does the same team carry the commercial interior design through to a finished space, or hand it to a separate contractor.
A single styled wall, often the office back wall or a reception wall, treated differently from the rest of the room to anchor it and carry brand or material interest. Why it matters: it is a high-impact, contained spend that lifts a space without redoing every surface. What to ask a firm: which one or two feature walls give us the most impact for the budget, and what finish keeps them looking good with daily wear.
Bespoke woodwork made for the space: storage units, wall paneling, reception desks, cabin fronts, pantry counters and built-in seating. Why it matters: joinery is where much of the bespoke cost and the longest lead times sit, and where finish quality is most visible. What to ask a firm: is the joinery made in your own workshop or bought in, and what is the lead time so it does not hold up handover.
A rendered 3D view of the office interior, produced from the design before anything is built, showing layout, materials, lighting and brand in a near-photographic image. Why it matters: it lets you approve the look and catch problems on screen, where changes are free, rather than on site, where they are costly. What to ask a firm: how many 3D visualisation views and revisions are included, and are the final materials shown the ones that will actually be installed.
Standardised, reconfigurable furniture systems for offices, desks, storage and partitions, built from interchangeable parts that can be rearranged or extended as the team changes. Why it matters: it lowers cost, shortens lead times and lets you reconfigure later without a refit. What to ask a firm: is the modular furniture from a system we can buy more of in future, and how does its cost and warranty compare with bespoke joinery for the same use.
The services behind the walls, the people who manage delivery, and the modelling tools that de-risk a build.
Mechanical, electrical and plumbing: the systems behind every wall and ceiling, including air conditioning and ventilation, power and lighting, water and drainage, and increasingly data and fire services. Why it matters: MEP is a large, hidden share of fit-out cost and the part most likely to cause delays or clashes if it is coordinated late. What to ask a firm: who designs and coordinates the MEP, and is it modelled against the architecture before site work starts.
Project management consultancy: an independent firm or person appointed to oversee delivery on the client's behalf, managing programme, cost, quality and the contractor so the client does not have to police the job themselves. Why it matters: on a larger or higher-risk fit-out a PMC protects the client's interest separately from the contractor. What to ask: do we need a PMC for this size of project, and if the same firm designs, builds and manages, who checks their work.
Building Information Modelling: a coordinated 3D model of the space and its services used to catch clashes, between ducts, pipes, cabling and structure, before they reach site, and to hold accurate quantities and specifications. Why it matters: on a complex or services-heavy fit-out, BIM cuts costly on-site surprises and rework. What to ask a firm: do you model the project in BIM, and will the architecture and MEP be clash-checked in the model before construction begins.
