Turnkey vs Design-Only Interiors: Choosing the Right Model

Turnkey vs design-only interiors: what is the difference?

In a turnkey interiors project, one company designs, procures, builds and hands over the finished home, taking single-point responsibility. In a design-only project, the designer provides drawings, 3D views and specifications, and you (or your contractor) hire vendors, buy materials and manage execution. Turnkey trades a higher single contract for convenience and accountability; design-only trades your time for more direct control over spending.

There is also a middle path, often called design plus supervision, where the designer creates the design and visits the site at key stages while you contract the vendors directly. Understanding all three helps you pick the model that fits your budget, schedule and appetite for coordination.

Side-by-side comparison of the three models

Turnkey offers the least effort and clearest accountability, design-only offers the most control and the most work for you, and design plus supervision sits in between.

How do costs compare between the two models?

Design-only looks cheaper on paper because you pay only a design fee and buy materials yourself, but coordination gaps, rework and wastage often narrow the difference. Turnkey pricing includes design, project management and a margin, but gives you a fixed, itemised scope.

• Turnkey: full home interiors in Delhi NCR typically range from about ₹1,500 to ₹4,500+ per sq ft of carpet area depending on specification; a 2BHK is often around ₹6 to ₹15 lakh and a 3BHK around ₹9 to ₹25 lakh, with luxury homes higher. These are indicative ranges only.
• Design-only: you pay a design fee plus all material, labour and vendor costs separately. Savings depend on your negotiating ability, time and how well the trades are coordinated.
• Hidden costs in design-only: material wastage, wrong orders, labour idle time, repeated site visits, transport, and fixing mismatched work between trades.
• Hidden costs in turnkey: vague specifications (such as "plywood" with no grade) and change requests after sign-off. Insist on a detailed bill of quantities.

When should you choose turnkey interiors?

Choose turnkey when you have limited time, are doing a full home or major renovation, live away from the site, or want one team accountable for design, quality and timelines.

• You are moving into a new flat or kothi with a fixed possession or move-in date.
• You are an NRI or live in another city and cannot visit the site often.
• The project involves many trades: civil, electrical, plumbing, false ceiling, carpentry, painting and furnishings.
• You want the finished home to match the 3D design closely.
• You prefer a single contract, payment schedule and point of contact.

Turnkey works best when the scope is detailed at the start. Asaya Interiors offers turnkey interior solutions covering floor plans, 3D design, construction and complete interiors for homes and commercial spaces.

When does design-only make more sense?

Design-only makes sense when you have a trusted contractor, enough time to supervise, and a smaller or phased scope, or when you simply want expert layouts and 3D views before deciding how to execute.

• You are renovating one or two rooms and already know reliable carpenters.
• You enjoy sourcing materials and have time for regular site visits.
• You want to phase the work over months as budget allows.
• Your builder or a family contractor is already handling civil work.
• You want a professional layout, 3D designs and floor plans to guide your own execution.

If you choose design-only, ask for complete working drawings, not just 3D views: dimensioned elevations, electrical and lighting layouts, false ceiling sections, joinery details and a material schedule. Without these, contractors improvise, and the result drifts from the design.

What a turnkey project looks like, stage by stage

A turnkey home interior project usually moves through six stages, from the first consultation to handover. For a typical 2BHK or 3BHK apartment, the build phase commonly takes around 8 to 14 weeks after design approval, depending on scope, material lead times and site conditions.

1. Consultation and site visit: understanding the family, lifestyle, budget and must-haves; measuring the site and noting existing conditions such as damp walls or old wiring.
2. Space planning: furniture layouts and floor plans, including any vastu preferences, reviewed until the flow works.
3. 3D design and material selection: realistic views of each room, followed by selection of laminates, veneers, stone, fabrics and fittings from physical samples.
4. Detailed quotation and agreement: an itemised bill of quantities, payment milestones and a written schedule.
5. Execution: civil changes, electrical and plumbing, false ceiling, carpentry (often factory-made modules plus on-site work), painting, lighting, and soft furnishings, coordinated by one site team.
6. Quality check and handover: a snag list walk-through, corrections, deep cleaning and a handover of warranties and care instructions supplied by manufacturers.

In a design-only project, you manage stages five and six yourself, which is where most of the time and stress lies. That is also where the brand philosophy of detail-obsessed execution matters most: every detail is intentional only if someone is on site making sure it is built that way.

Risks to watch for in each model

The main turnkey risk is an under-specified quotation; the main design-only risk is coordination failure between trades. Both are manageable with the right paperwork.

Turnkey risks and safeguards

• Ask for brand, grade and thickness for boards, hardware and finishes in the quotation.
• Link payments to clear milestones rather than time.
• Agree on a change-request process with written approvals and costs.
• Get a written project schedule and a handover checklist.
• Ask what after-sales support is provided and for how long, in writing.

Design-only risks and safeguards

• Sequence trades carefully: electrical before false ceiling, false ceiling before carpentry installation, painting after most carpentry.
• Keep one person responsible for measurements.
• Budget a contingency of around 10% to 15% for rework and price changes.
• Book the designer for a few paid site visits at critical stages.
• Check material deliveries against the specification.

Choosing the right firm matters as much as the model; our guide on how to choose the best interior designer lists the questions to ask.

Questions to ask before you decide

Ask these questions of any interior design company before signing, whichever model you choose.

1. What exactly is included, and what is excluded?
2. Will I get a detailed bill of quantities with brands and specifications?
3. How many design revisions are included?
4. Who will be my single point of contact on site?
5. What is the payment schedule and how is it linked to progress?
6. What is the realistic timeline, and what could delay it?
7. How are changes and extra work priced?
8. Can I see completed projects or visit an ongoing site?
9. What after-sales support is provided?

Good design starts long before move-in day, and so does good planning.
