There's a decision that quietly shapes your entire studio, and most owners make it by accident rather than on purpose, which is whether you're a design-only practice or a turnkey one. The two look similar from the outside, both end with a beautiful home, but they're priced in completely different ways, they earn money from completely different places, and they carry completely different risk, so getting this wrong means you're either leaving margin on the table or taking on execution headaches you never charged for. Let me lay out both honestly, with real rupee logic, so you can decide which one you're actually running and price it properly.
What each model really means
Design-only means you sell your intelligence and stop there. Drawings, 3D views, material palettes, the specification, maybe some site supervision, and then the client executes it with their own contractor or a vendor you recommend. You're paid a professional fee and you never touch the client's material money.
Turnkey means you carry the whole thing. You design it, you procure it, you build it, and you hand over keys. The client pays you one number and you're responsible for everything from the false ceiling to the last drawer handle. Your fee is now buried inside a much bigger figure, and your margin comes not just from design but from the markup on supply and execution.
Neither is better in the abstract. The catch here is that a lot of studios say "design-only" on their website and then quietly do turnkey work without ever pricing in the execution risk, and that's the version that kills studios. If you want to see how a full project actually breaks into layers, I laid that out in how to quote for a full home interior, and this post is the model-level decision that sits above it.
How the fee is built in each model
This is where the two diverge sharply, so here's the plain comparison.
| Factor | Design-only | Turnkey |
|---|---|---|
| What you sell | Drawings, 3D, specs, selection | The finished, built home |
| How you're paid | Fee per sq ft or % of project | One all-in figure per sq ft |
| Rough fee basis | ₹75 to ₹250 per sq ft, or 8 to 12% | ₹1,200 to ₹3,500+ per sq ft all-in |
| Where margin comes from | The design fee itself | Design fee plus markup on supply and execution |
| Cash you handle | Only your fee | The client's entire project budget |
| Your risk | Low, you don't own execution | High, you own quality, delays, and rates |
| Team you need | Designers and drafters | Designers plus procurement and site staff |
Notice the cashflow line, because it matters more than people expect. In design-only you handle only your fee, which is clean and low-risk but caps how much you can earn from a single project. In turnkey you're routing the client's entire budget through your studio, which is where the real money is, and also where a single procurement mistake can wipe out the profit from three projects.
Where the money actually comes from
Let me be blunt about margin, because this is the part nobody says out loud. In design-only, your profit is your fee minus your team's time, and that's it, so your job is to be efficient and not over-service. In turnkey, your fee is often a smaller slice, and the bigger contribution comes from the disciplined markup you hold on materials, modular units, and labour.
That turnkey markup is only real if you actually hold it, and holding it is a procurement discipline, not a hope. The gap between the rate you quoted the client and the rate you paid the vendor is your margin, and if that chain is running on WhatsApp and memory, it leaks. This is exactly why running procurement cleanly from PO to delivery is the make-or-break skill for a turnkey studio, and why protecting your margin on every project is a system, not a personality trait.
Real rupee ranges to price against
Here's how the two shake out in practice for a metro or large tier-2 city in 2026, framed roughly because finish level swings everything.
A design-only mandate for a 1,200 sq ft flat might be ₹1.2 to ₹3 lakh in fee, and your only cost is your team's hours, so a well-run design-only project can hold a very healthy margin percentage precisely because you're not carrying material risk. A turnkey version of the same flat might be ₹18 to ₹30 lakh all-in, of which your genuine profit might be 12 to 20% if your procurement is tight, and closer to nothing if it isn't.
So the counterintuitive truth is that turnkey has a bigger absolute rupee opportunity and a bigger absolute risk, while design-only has a smaller ceiling but a cleaner, more defensible margin. Which one suits you depends less on ambition and more on whether you've built the operational muscle to handle other people's money without leaking it.
When to choose which
Here's the honest guidance I give younger studios. Start design-only if you're small, if your systems aren't tight yet, or if you're in a city where good execution partners are easy to find, because it keeps your risk low while you build a reputation. Move toward turnkey when you have the procurement and site discipline to hold your markup, and when clients are actively asking you to "just handle everything", which they will, because most Indian homeowners would rather pay one team than manage five vendors.
Key takeaways
- Design-only sells intelligence at low risk with a capped ceiling
- Turnkey routes the client's whole budget through you, with bigger upside and bigger risk
- Turnkey margin is real only if your procurement discipline holds the markup
- Pick the model your systems can actually support, then price it honestly
Plenty of studios also run a hybrid, design-only for clients who want to execute themselves and turnkey for those who want it all handled, and that's completely fine as long as you price each mandate as what it truly is and never accidentally do turnkey work on a design-only fee.
The system decides whether the model works
Whichever model you land on, the thing that makes or breaks it is whether the numbers are connected. In design-only you still need clean fee invoicing and GST compliance, and in turnkey you need the quote, the purchase orders, the deliveries, the client approvals, and the invoices all tied together, because the moment they live in separate tools the margin you priced in evaporates in reconciliation.
That's the whole reason we built Designa as one connected system instead of five disconnected tools. Your quote becomes the client-approved board, the board drives your purchase orders, the PO tracks to delivery, and the milestone becomes a compliant GST invoice with a Razorpay link, all in one workspace that also keeps your studio bookkeeping tidy and syncs to Tally or Zoho Books so your accountant isn't chasing you. And before any of that, the very first client touchpoint, charging properly for that first site visit or consultation, sets the tone for whether they treat you as a professional or a free quote machine.
On the business-setup side, whichever model you run, it pays to formalise the studio, because turnkey especially means signing contracts worth tens of lakhs and clients want to see a real registered entity. A quick Udyam MSME registration costs nothing, incorporation runs through the MCA portal, and if you're building something ambitious the Startup India resources are worth a read.
The bottom line
Turnkey versus design-only isn't a branding choice, it's a pricing and risk choice, so decide which one your studio can actually operate, price the fee honestly in that model, and never let a turnkey project run on a design-only fee. Get the model right and the margin follows.
Frequently asked questions
What's the difference between turnkey and design-only pricing?
Design-only charges a professional fee, roughly ₹75 to ₹250 per sq ft or 8 to 12% of project value, and you don't handle the client's material money. Turnkey charges one all-in figure, roughly ₹1,200 to ₹3,500+ per sq ft, and your margin comes from both the design fee and the markup on supply and execution.
Which is more profitable, turnkey or design-only?
Turnkey has a bigger absolute rupee opportunity because you route the whole project budget, but that profit is only real if your procurement discipline holds the markup. Design-only has a lower ceiling but a cleaner, lower-risk margin.
Can I offer both models in the same studio?
Yes, many studios run a hybrid. The key is to price each mandate honestly as what it is, and never do turnkey execution on a design-only fee.
How do I stop turnkey projects from leaking margin?
Keep the quote, purchase orders, deliveries, approvals, and invoices in one connected system so the rate you quoted and the rate you paid never silently drift apart.
