What “turnkey” means in interiors
Turnkey interior work is a single-contract delivery model in which one firm takes responsibility for design, procurement, execution and handover, so the client receives a finished space ready for use. It differs from hiring a designer and separate contractors, where responsibility is split and coordination falls on the owner.

Stage-wise process

- Concept and layout. Furniture plans, ceilings and lighting layout.
- 3D and material selection. You approve the visual direction and finishes.
- BOQ and contract. Itemised quantities, rates, inclusions, exclusions, payment milestones.
- Civil and services. Demolition, masonry, electrical and plumbing.

- Snagging and handover. Defects list, rectification and handover documents.
Typical inclusions and exclusions
Published Delhi guides commonly list the following as included in a turnkey package: modular furniture, carpentry, kitchen and wardrobe installation, false ceiling and lighting, and basic electrical and plumbing work. Items frequently excluded are appliances, electrical upgrades, civil modifications, changes after design approval, and GST or service charges. The exact split varies by firm, so ask for it in writing.
Indicative costs (estimates)
DesignCafe’s 2026 Delhi guide lists turnkey 2BHK interiors at roughly ₹4.5-6.5 lakh (budget), ₹7-10 lakh (mid-range) and ₹11-15+ lakh (luxury). InteriorAtoZ lists turnkey project budgets of ₹5-15 lakh for a 2BHK and ₹8-25 lakh for a 3BHK, with design-only fees running separately at about 5-10% of project value or a per sq ft rate. Sources overlap but do not match, so use them to frame questions, not to judge a quote. See also our cost per sq ft guide.
How to compare two turnkey quotes
- Match each BOQ line: area, material, brand and grade.
- Check whether civil, electrical and painting are included.
- Compare hardware brands for hinges, channels and handles.
- Look at warranty terms and service response commitments.
- Ask what happens if you change something after approval.

Red flags
- A lump-sum quote with no itemisation.
- Pressure to pay a large advance before design approval.
- Unclear subcontracting and no named supervisor.
- Material descriptions like “branded plywood” with no brand or grade.
Payment schedule
Payments should be linked to completed milestones such as design approval, material delivery, carpentry completion and handover. Review our contract and payment schedule guide before signing.

Contract documents to request from a turnkey contractor
- Scope of work: Rooms, items and quantities covered.
- BOQ with rates: Per-line material, brand and grade.
- Drawings: Layouts, elevations and electrical and ceiling plans.
- Schedule: Milestones with dates.
- Payment plan: Linked to milestones.
- Variation clause: How extra work is approved and priced.
- Warranty terms: Duration and coverage for joinery, finishes and workmanship.
Site management signals to look for
A well-run turnkey site has a daily work plan, protected finished surfaces, material storage, safe temporary electrical arrangements and a supervisor who can answer questions on the spot. Ask to see a live site and observe whether it looks organised. Cleanliness and discipline often predict final quality.
How South Delhi conditions affect execution
- Society rules: Working hours, lift usage and debris disposal differ between societies and colonies.
- Older buildings: More hidden issues in wiring, plumbing and waterproofing.
- Access: Narrow lanes can affect material delivery timing and cost.
Discuss these in your first meeting so the schedule reflects real conditions.
When turnkey is not the right model
If you only need a repaint, a small repair or one piece of furniture, a turnkey contract adds overhead. If you enjoy managing vendors and have time on site, design-only may give you more control. Read renovation contractors in Delhi for lighter scopes.
