Most people building or renovating a home or office in Delhi NCR run into this question early: do I hire an architect and a contractor separately, or find someone who does both? There's a third option too — labour-rate contracting, where you buy materials and the contractor charges only for work done. Each model has a different shape, a different risk profile, and a different answer to the question that matters most when something goes wrong: who's responsible.
The three models, side by side
Architect + contractor, hired separately
You hire an architect (or interior designer) to draw up the design, and a separate contractor to execute it. The architect isn't on site every day. The contractor isn't bound by the design intent beyond what's on paper. When the site deviates from the drawing — and it usually does, because drawings never anticipate every real-world constraint — you're the one standing between two parties, each pointing at the other.
This model works when you have the time to project-manage, or you hire a third party to do it for you. It can also produce excellent results when the architect and contractor have worked together before and trust each other. But that trust isn't something you can verify in advance. You're betting on a relationship you didn't build.
Labour-rate contracting
Here, you buy the materials — tiles, plywood, laminate, hardware, paint — and the contractor quotes only for labour: cutting, fixing, finishing. This is the cheapest model on paper because you're avoiding contractor margins on material. It's also the most demanding on your time. You're now a procurement manager, sourcing from multiple vendors, tracking deliveries, matching material lead times to the site schedule, and absorbing the cost of any material that's wrong, short, or delayed.
Labour-rate contracting suits people who know the trade — either professionally or through prior renovation experience — and who have the bandwidth to spend weekends at Kirti Nagar or Naraina chasing suppliers. For a first-time client with a full-time job, it's usually a false economy: the savings on margin get eaten by mistakes, rework, and time.
Turnkey design-build
One contract. One point of contact. The same company designs the space, quotes it as a single itemised number, procures every material, executes every trade, and hands over a finished, usable space. There's no design-side entity blaming the execution side, and no execution side blaming an absent designer. If the built space doesn't match what was quoted, there's exactly one party accountable — not two parties each holding half the story.
This is the model Interiovation operates on.
Who each model suits
- Architect + contractor separately suits clients with an existing, trusted relationship with an architect, or those willing to actively manage the coordination gap themselves.
- Labour-rate contracting suits clients with trade knowledge, spare time, and appetite for procurement legwork — typically smaller jobs or clients who've renovated before.
- Turnkey suits clients who want one itemised quote, one execution timeline, and one company to hold accountable — home owners with full-time jobs, and businesses that need an office or clinic fit out without diverting internal staff to manage it.
If your primary constraint is time rather than money, turnkey is built for exactly that trade-off.
How the 5-step process works
A design-build engagement moves through five stages. Each one exists to remove a specific kind of ambiguity before it becomes a site problem.
1. Listen & Measure
The process starts with a site visit and a conversation, not a sales pitch. Measurements are taken, existing conditions are documented — electrical points, plumbing lines, structural columns, natural light, external constraints like society rules or building bylaws. This stage also surfaces budget range, timeline, and how the space actually gets used day to day, which matters more than how it looks in a mood board.
2. Design & Quote
Design intent gets translated into drawings and a layout that respects the measured constraints from step one. Alongside the design, an itemised quote is prepared — line by line, not a lump sum. This is where the turnkey model earns its keep: the quote reflects everything from civil work to the last cabinet handle, so there's no scope creep hiding behind vague line items later.
3. Plan & Procure
Once the design and quote are approved, execution planning starts. Materials get procured against the approved specification — the exact laminate, the exact tile batch, the exact hardware brand — so there's no last-minute substitution because something wasn't ordered in time. An execution sequence is set: what happens first, what depends on what, and how long each phase should take.
4. Build & Report
Site execution happens against the plan, with progress reported back so the client isn't left guessing what's happening between site visits. This is the stage where a single accountable contractor matters most — if plumbing work reveals an issue that affects the false ceiling design, the same team that's responsible for both can resolve it on the spot, instead of triggering a blame cycle between separate vendors.
5. Handover & Care
Handover isn't just keys and a broom-clean site. It includes a walkthrough against the original quote and design, a snag list closed out before sign-off, and a point of contact for anything that needs attention after move-in.
Where the cost accountability sits
This is the question that actually separates the models. In a turnkey contract, cost accountability sits with one entity, for the whole scope, against one itemised quote. If a line item was quoted and not delivered, or delivered to a lower spec than quoted, there's no second party to blame — the accountability doesn't split.
In the separated model, cost accountability is split between design and execution, and disputes over what caused a cost overrun — bad drawings or bad execution — are common precisely because both parties have plausible deniability. In labour-rate contracting, cost accountability for materials sits entirely with the client, since the contractor never touched procurement.
Turnkey doesn't make a project cheaper by definition — see the indicative band below — but it does make cost accountability legible. You know, before work starts, what number to hold the contractor to.
As an indicative reference, turnkey interior fit-outs in Delhi NCR typically run in the ₹1,500–2,500 per sq ft band, depending on scope and finish level. This is indicative only — actual numbers depend on the brief.
Frequently asked questions
Is turnkey more expensive than hiring separately?
Not necessarily. Turnkey pricing includes contractor margin on materials and coordination, which the separated model avoids on paper — but the separated model often costs more in practice once you account for delays, rework from miscommunication between architect and contractor, and the value of your own time spent coordinating.
Can I still have design input in a turnkey model?
Yes. The Design & Quote stage is where design intent gets set, and it's a collaborative stage, not a handed-down one. The difference from the separated model is that the same company that designs it is also accountable for building it, so there's no incentive to hand off an impractical design and let someone else deal with executing it.
What happens if I want changes mid-project?
Changes are normal on any real project. In a turnkey contract, a change request gets priced and scheduled against the same itemised quote structure, so you see the cost and timeline impact before agreeing to it — rather than discovering it later as an unexplained overrun.
How long does a typical turnkey fit-out take?
Timelines depend heavily on scope — a single room differs enormously from a full office floor. The Plan & Procure stage is where a realistic timeline gets fixed, based on the actual design and material lead times, rather than a generic estimate given before the scope is known.
