Turnkey Interior Design in Mumbai: What Is Included From Design to Final Handover? — Tachi India

The phrase 'turnkey interior design' is used widely in Mumbai's interior design market — and understood very differently by different people. For some, it means a firm that handles the design and the carpentry and leaves the client to manage everything else. For others, it means a firm that manages every single aspect of the project from the first consultation to the day they hand over the keys to a completely finished, ready-to-live-in home. The difference between these two interpretations — in terms of client experience, project quality, and final outcome — is enormous.

At Tachi India, one of Mumbai's most trusted interior design firms, turnkey means exactly what it should mean: you hand us the keys to your empty flat, and we hand them back to you when it is completely finished. Every trade, every material, every vendor, every quality check — from concept design to civil work to carpentry to furniture to final styling — is managed by our team. In this comprehensive guide, we explain exactly what a genuine turnkey interior design project includes in Mumbai, why it is the most effective approach for most homeowners, and what to look for when choosing a turnkey interior design company in Mumbai.

What Does Turnkey Interior Design Actually Include?

A genuine turnkey interior design service in Mumbai covers every stage and every trade involved in transforming an empty apartment into a fully finished home. At Tachi India, our turnkey service is structured across eight distinct phases — each with its own team, its own quality standards, and its own client checkpoint.

Phase 1: Concept Design and Space Planning

Every Tachi India turnkey project begins with a thorough discovery process. We conduct a detailed lifestyle brief with the client — understanding how the household lives, works, cooks, entertains, and rests. We complete a detailed site measurement and assessment, identifying the existing infrastructure, any civil deficiencies, and the opportunities and constraints of the specific floor plan. From this foundation, our senior designers develop a complete concept — including layout plans, 3D visualisations for every major room, a material mood board, and a colour palette — presented to the client for review and approval.

This phase typically takes three to five weeks and is the most valuable investment in the entire project. A well-resolved design concept is the blueprint that makes every subsequent phase faster, smoother, and more likely to produce the result the client envisioned.

Phase 2: Detailed Design and Full Material Sign-Off

Once the concept is approved, Tachi India develops the detailed design — producing precise construction drawings for every piece of custom carpentry, electrical layout plans showing the position of every switch, socket, light point, and circuit, plumbing layout and sanitary fitting specifications, false ceiling design with lighting placement, and a complete furniture schedule. Simultaneously, we prepare a full material specification board with physical samples of every laminate, tile, stone, fabric, and finish to be used in the project. The client reviews and signs off on every material before any order is placed.

This sign-off process is what distinguishes professional turnkey firms from those that simply begin work and make decisions as they go. Every decision made here prevents a costly, time-consuming change later.

Phase 3: Itemised Quotation and Contract

Tachi India provides a fully itemised quotation covering every category of work — civil, electrical, carpentry, loose furniture, soft furnishings, lighting, décor, and project management — before any contract is signed. Every line item specifies the material, the quantity, the finish, and the unit rate. GST is shown separately. The payment schedule is tied to project milestones — not to calendar dates — so the client retains financial leverage throughout the project. The contract specifies the timeline, the scope, the change management process, and the warranty terms.

Phase 4: Material Procurement and Fabrication

Once the contract is signed and the first payment milestone is cleared, Tachi India initiates simultaneous procurement and fabrication. All tiles, laminates, hardware, sanitary ware, and loose furniture are ordered. Custom carpentry — modular kitchen, wardrobes, TV unit, and all other built-in furniture — goes into fabrication at our trusted workshops. This phase runs in parallel with the early civil work on site, compressing the overall timeline significantly.

Tachi India's procurement network in the Wadala and central Mumbai area — built over years of project delivery — gives our clients access to quality materials at competitive prices and reliable lead times. We track every order and flag any supply chain issues proactively rather than discovering them when they cause delays on site.

Phase 5: Civil Work Execution

Civil work is the foundational layer of any interior project — and the one that most directly determines the quality and longevity of everything that follows. Tachi India's civil scope covers demolition where required, waterproofing in all wet areas, floor levelling and sub-floor preparation, flooring and tiling installation, false ceiling construction, partition walls and modifications, painting with appropriate primers and finishes, and bathroom fit-out including all plumbing connections. Civil work in Mumbai must be executed with particular attention to waterproofing quality — the cost of waterproofing failures in the city's monsoon climate is consistently underestimated by firms that cut corners here.

A dedicated Tachi India site supervisor is present on site during all civil work phases — conducting daily quality checks and ensuring that every trade performs to the specifications in the design drawings.

Phase 6: Electrical Work

Tachi India manages all electrical work as part of the turnkey scope — from the distribution board through to every switch, socket, light point, AC power point, and kitchen appliance circuit. Electrical work is executed in coordination with the civil phase, with all conduit and wiring installed before plastering and before false ceilings are closed. The lighting plan is implemented exactly as designed — with every fitting placed at the specified position, every circuit allocated to the correct zone, and every dimmer and smart switch installed and tested before wall painting begins.

Phase 7: Carpentry and Modular Unit Installation

The installation of all fabricated carpentry — modular kitchen, wardrobes, TV unit, crockery units, study tables, and all other custom built-ins — is one of the most complex and most visible phases of any turnkey project. Tachi India's carpentry installation team works from the detailed drawings produced in Phase 2, installing every unit to the specified dimensions and positions, fitting all hardware, and conducting a thorough quality inspection before any unit is signed off. The fit and finish of installed carpentry — the evenness of gaps between doors, the smooth operation of every drawer, the precision of every corner joint — is one of the most telling indicators of a firm's execution quality.

Phase 8: Furniture, Soft Furnishings, Styling, and Handover

The final phase of a Tachi India turnkey project is the one that most people think of when they imagine interior design — and the one that most firms either rush or skip. Loose furniture is delivered and positioned. Curtains and blinds are installed. Rugs are laid. Artwork is hung. Plants are positioned. Every decorative accessory is placed with intention. The lighting scenes are set and tested. And the space is photographed for the Tachi India portfolio — a moment that only happens when the team is satisfied that the space looks exactly as it was designed to look.

A thorough snagging walkthrough is conducted with the client — every observation is documented and addressed before the project is formally closed. All warranties on materials and workmanship are provided in writing. And Tachi India remains available for after-handover support because our relationship with our clients does not end at the door.

Why Turnkey Interior Design Is the Right Choice for Most Mumbai Homeowners

The alternative to a turnkey approach — managing multiple vendors, contractors, and suppliers independently — sounds appealing in theory and is almost always a painful experience in practice. Coordinating a civil contractor, an electrician, a plumber, a carpenter, a modular kitchen supplier, a flooring company, a painter, a furniture store, and a curtain shop simultaneously — while maintaining a full-time job and a family — is a genuinely demanding undertaking. Every interface between trades is a potential point of delay, error, and cost blowout. Every vendor has an incentive to blame another when things go wrong.

A genuine turnkey firm takes all of this off the client's plate. One point of contact. One accountable party. One integrated team that coordinates every trade. For Mumbai's busy professionals — who have demanding careers, families, and lives that cannot be put on hold for months — this is not a luxury. It is the only way to get a great interior delivered without sacrificing your sanity.

What Turnkey Interior Design Costs in Mumbai in 2026

A complete turnkey interior for a 2BHK apartment in Mumbai ranges from Rs 12 lakhs to Rs 35 lakhs in 2026 depending on specification level. A 3BHK complete turnkey interior ranges from Rs 25 lakhs to Rs 55 lakhs. Tachi India's turnkey service is priced to include design, project management, all trade coordination, quality supervision, and the final styling — not just the cost of materials and labour. The project management and coordination provided by a genuine turnkey firm is a significant and quantifiable service, and it is priced transparently in every Tachi India quotation.

Frequently Asked Questions: Turnkey Interior Design in Mumbai

What is the difference between turnkey interior design and partial interior design services in Mumbai?

Turnkey interior design covers the complete scope of work from concept to handover — all trades, all materials, all coordination managed by one firm. Partial interior design services cover a specific subset of the work — typically design and carpentry, or design only — leaving the client to manage other trades independently. For most Mumbai homeowners, turnkey is significantly less stressful and often more cost-effective in total, because the coordination efficiency of a single accountable firm reduces errors, rework, and delays that inflate the total cost of a self-managed project.

How long does a turnkey interior design project take in Mumbai?

A complete turnkey interior for a 2BHK apartment in Mumbai typically takes 12 to 16 weeks from design sign-off to handover with Tachi India. A 3BHK takes 16 to 22 weeks. The design phase takes three to five weeks before execution begins. Total time from initial consultation to handover is typically 15 to 22 weeks for a 2BHK and 20 to 28 weeks for a 3BHK. These are realistic timelines based on actual project delivery — not the optimistic estimates that many Mumbai firms provide to win the brief.

Does Tachi India handle appliance installation as part of the turnkey service?

Tachi India designs and prepares all appliance niches, power points, and plumbing connections as part of the turnkey scope. Appliance procurement — refrigerator, washing machine, microwave, chimney and hob, water purifier, and ACs — is typically managed by the client directly. However, we advise on appliance specifications that integrate with the kitchen and home design, review appliance choices for size and technical compatibility before purchase, and coordinate the installation of client-purchased appliances with our trades during the appropriate project phase.

How does Tachi India handle quality control in a turnkey project?

Quality control is embedded into every phase of a Tachi India turnkey project — not conducted as a single inspection at the end. A dedicated site supervisor conducts daily checks during civil and electrical work. Carpentry is inspected at the workshop before it leaves for site installation. Every installed element is checked against the design drawings before the next phase begins. And a formal snagging inspection with the client is conducted before handover — with every observation addressed before the project is closed. This multi-stage quality process is what consistently produces the finish quality that Tachi India is known for across Mumbai.

Can I make changes during a Tachi India turnkey project?

Yes — but through a formal process. Tachi India has a documented change management system: every change to the original approved scope is submitted as a written change request, assessed for cost and timeline impact, and communicated to the client in writing before any work proceeds. This protects the client from unexpected costs and protects the project timeline from the cascading delays that unmanaged changes cause. The most important thing any client can do to keep a turnkey project on track is to invest the time in the design sign-off phase to make all decisions before execution begins.
