There are three ways to buy interiors in India, and most owners choose between them without being told they are choosing at all. The distinction that matters is not who is more talented — it is who is accountable when the site does not match the drawing. This page sets out all three honestly, including the cases where the right answer is not us.
They are often described as if they were the same service at different price points. They are not. Each sells something genuinely different, and each leaves a different risk with you.

Sells drawings and decisions. Layout, spatial planning, material and finish selection, 3D visualisation, and a specification somebody else builds to. What you keep afterwards is a document. Whether it becomes a good home depends on who builds it.
Sells delivered work. Procurement, fabrication, site supervision, sequencing, snagging and handover, built to a drawing that already exists. Bring a studio's set, an architect's set, or a builder's standard layout. The risk carried is that the drawing is worth building.
Sells both under one contract. One firm draws it and one firm builds it, so there is a single point of accountability and no coordination gap. The trade is that the party checking the work is the party that did it.
The row that decides most projects is the last one. Everything above it is preference; that one is risk.

The useful question is not which model is best. It is which risk on your project is the largest, because each model is good at absorbing a different one.
Significant spatial reconfiguration. An unusual floor plate. Heritage or architectural constraints. A distinctive aesthetic you cannot brief in words. A home where the layout itself is what you are paying to improve. In these cases the drawing is where the value is created, and buying it from a firm whose entire business is producing it is the right call.
A studio that did not build the work has no incentive to sign off on its own defects. On a large, long or high-value project, paying a second party to inspect and certify against the drawing is a genuine control — and it is the one thing design-and-build structurally cannot give you.
If your architect or studio has produced a buildable set, you do not need to buy design again. What you need is procurement, sequencing and supervision, priced against an itemised BOQ. This is also the right route when a builder's layout is already sound and the real risk is finish quality rather than planning.
Conventional apartment, workable layout, and an owner who does not want to arbitrate between two suppliers — particularly an owner living in another city or country. One contract, one number, one party answering the phone. You trade the independent check for the absence of a coordination gap, and on a straightforward project that is usually the better trade.
Where a designer earns a fee is in the decisions that are hard to reverse — layout, lighting, storage planned against how you actually live, finishes that have to work together across rooms. Where a fee is wasted is buying a package of renders for a standard two-bedroom flat whose layout was never going to change. Any firm that says you always need a designer is selling rather than advising.
The fee structures create different incentives. None of them is dishonest, but knowing which you have signed changes which questions are worth asking.
Common for studios. Simple and transparent, with one property worth naming: the fee rises as your spend rises. That is not a reason to avoid it, but it is a reason to agree the basis and a cap before selections begin rather than after.
Also common for studios, and it decouples the fee from your material choices. Confirm which area basis it uses — carpet, built-up or super built-up — because the same rate against built-up area on a typical flat can be a quarter more than against carpet.
How a contractor is paid: each line has a quantity, a unit and a rate, and money follows physical progress. It is the most checkable of the structures, because the total is arithmetic you can audit rather than a figure you accept.
One number for the whole job, from any of the three. Easy to compare and easy to misread — a lump sum rewards reducing scope, so it is only safe once the scope behind it is itemised. That is the whole subject of our quote comparison guide.
This page compares three models and we are one of them, so the disclosure belongs on the page rather than in the small print.
AlcorOne is an execution-first interior contracting firm. We deliver turnkey fit-outs against an itemised Bill of Quantities, and we work both ways — building to drawings a client's own architect or studio has produced, and handling design and execution together where a client wants a single point of accountability. We are not a design-led studio. On a project whose central difficulty is architectural or aesthetic rather than one of delivery, an independent studio is the better first appointment, and we would rather say so here than have you find out three months in.
The corollary is the part we will defend: on a project where the layout is sound and the risk is execution, the money is better spent on supervision, material grade and hardware than on a second design fee. That is a position, not a neutral fact, and you should weigh it knowing who is writing it.
A studio sells drawings and decisions; a contractor sells delivered work built to a drawing that already exists. The practical difference is not skill but where accountability sits — with a studio and a separate contractor, each can blame the other and you arbitrate.
When the design problem is genuinely hard: real spatial reconfiguration, an unusual floor plate, heritage constraints, or an aesthetic you cannot brief in words. Also when you specifically want an independent party inspecting the build.
Usually — one margin instead of two, and no coordination gap. But separating design from execution buys independence, which is worth real money on a large or unusual project and is often redundant on a conventional flat.
Usually, but confirm two things in writing: that the fee includes the right to build with anyone, and that the set is detailed enough to price — joinery sections, hardware schedules and service coordination, not just renders.
It depends on the contract, which is why it must be settled before signing. Under design-and-build, one firm has nowhere to point. Under a split appointment, appoint the studio to inspect and certify the contractor's work and put that duty in writing — otherwise you have two suppliers and no referee.
The model predicts this more reliably than the brand does. Execution contractors and design-and-build firms price against a Bill of Quantities as a matter of course, because it is the document their own site work is billed from; a design-led studio more often issues a design fee plus a separate contractor's quote it does not control. But the test is not whether a firm can produce a BOQ — it is whether you sign it before work begins, and whether it names quantities, rates, hardware brands and board grade per zone. A line reading “wardrobe: 1 no.” is a lump sum with extra steps. AlcorOne works to an itemised BOQ signed off before site work starts, with grade stated per zone, and the signed grade is what the carcass warranty is conditional on. Two questions separate a real BOQ from a nominal one: is any line marked “as per site” or “to be decided”, and what is the written process when a quantity changes mid-project?
Not always. For a conventional 2 or 3BHK with a workable builder layout, a competent contractor working to an itemised BOQ and production drawings will deliver it. A designer earns the fee on the irreversible decisions — layout, lighting, storage, finish combinations.
Execution-first contracting. We build to your architect's drawings, or handle design and execution together. We are not a design-led studio, and where the problem is architectural rather than one of delivery, a studio is the better first appointment.
Yes, and you should. The studio produces the specification; the contractor prices it line by line. A studio's cost estimate is not a BOQ, and the two are frequently confused — one is a projection, the other is a priced list you can hold someone to.
A studio is normally paid a design fee against drawing stages. An execution contractor is paid against build progress: Projects start on a 20% deposit of the total contract value, adjusted against the final invoice. The balance is released against milestones tied to progress — material procurement, civil and carpentry completion, finishing and handover — and the exact milestone schedule is written into each project's payment schedule, because it moves with size, scope and site condition. Design-and-build merges both into one contract, which is what makes the line between design fee and build cost hard to read in it.
It moves work earlier rather than adding it. The build timeline is estimated at BOQ stage either way; what a settled drawing set changes is how many variations arrive mid-programme, and Anything outside the signed BOQ is a variation: costed and confirmed in writing before it is executed, with its own price and timeline impact.
In India the difference is statutory, not stylistic. “Architect” is a protected title: it requires registration with the Council of Architecture under the Architects Act, 1972, and an architect's work covers the building itself — structure, envelope, and the drawings a municipal sanction is granted against. “Interior designer” is not a protected title, carries no registration requirement, and the work sits inside a shell somebody else built and got approved. For a flat that decides itself: if you are not touching structure, the slab, the facade or anything that will be inspected against a sanctioned plan, an architect is not the appointment you need. Bring one in for a villa, a floor plate reconfiguration, or a new structural opening. AlcorOne is neither — it is an execution contractor, and where an architect or designer is already appointed it builds to their set.
Yes, and it is a legitimate way to buy independence — it is the same arrangement described above, read from the buyer's side. Settle two things in writing before paying: that the fee includes the right to build with any contractor, and that the set is detailed enough to price. The working test for the second is whether the package can be turned into a Bill of Quantities line by line — joinery sections, hardware schedules and service coordination, not renders. A drawing set that cannot be priced is not a buildable set however good it looks. Then expect the contractor to re-measure on site and price against the drawings, because a designer's cost estimate is a projection and a BOQ is a priced list you can hold someone to. AlcorOne builds to a set it did not produce, and states at BOQ stage which lines the set leaves unresolved rather than assuming them.
Share the property, the scope and whether you already hold drawings. If an independent studio is the better first appointment for what you are describing, we will say so. If not, you will get an itemised BOQ with quantities, rates, named hardware and grade stated per zone.
