How Long Does a Full Home Interior Take?

"How long will it take?" is the first question every homeowner in Haldia, Kolkata, and Purba Medinipur asks after "How much will it cost?" The answer depends on scope, site readiness, material lead times, and whether you are refreshing one flat or executing full turnkey interiors from bare shell.

Royal Decor Interior Designer publishes realistic schedules — not optimistic ones that collapse under monsoon delays or pending builder handovers. This guide walks through each phase of a typical full-home project so you can plan move-in dates, rental overlap, and festival housewarmings with eyes open.

Timelines differ between a freshly handed-over New Town 3BHK and a occupied renovation in an older Haldia cooperative — we cover both patterns so you can map this guide to your own possession letter and society work-hour rules.

A honest timeline protects your lease, your housewarming date, and your sanity.

Phase 1: Design and approvals (2–5 weeks)

Site measurement, layout discussion, 3D visualisation, material selection, and quotation finalisation typically take two to five weeks for a 3BHK, depending on how quickly decisions are made. Delays here — flip-flopping on kitchen layout or wardrobe internals — push everything downstream.

We recommend a single decision-maker per room or a weekly sign-off meeting. Parallel approvals (you choose tiles while we finalise modular drawings) compress this phase without rushing quality.

• 2BHK: often 2–3 weeks to design freeze
• 3BHK: 3–5 weeks with multiple revision rounds
• Villa or duplex: 5–8 weeks for coordinated floors

Phase 2: Production and procurement (3–6 weeks)

Modular kitchen, wardrobes, and TV units are factory-produced after design freeze. Standard laminates and hardware ship in three to four weeks; imported finishes, custom glass, or special-order veneers add two to four weeks.

Civil materials — tiles, sanitaryware, doors — are procured in parallel. Royal Decor does not start demolition until critical items are on site or confirmed in transit, avoiding half-tiled bathrooms waiting for a back-ordered basin.

Phase 3: Civil and MEP on site (4–8 weeks)

Electrical rewiring, plumbing shifts, false ceiling, waterproofing, tiling, and painting form the longest variable phase. A 2BHK with moderate civil work often needs four to six weeks; heavy structural changes or builder-delayed handovers extend this.

Monsoon months in West Bengal add buffer — exterior painting and certain adhesives need dry windows. We schedule wet-area work and interior painting with weather contingencies built into contracts.

Phase 4: Modular installation and finishing (2–4 weeks)

Kitchen and wardrobe installation follows completed civil and paint. Sequential trades — electricians fitting appliances, glass shower panels, final hardware — typically need two to four weeks for a full flat.

Snag lists and touch-up painting happen in the final week. We walk every room with you before handover, documenting minor fixes with committed completion dates.

Realistic totals and what speeds things up

A typical 3BHK turnkey interior from design freeze to handover runs 12–18 weeks in favourable conditions. Bare-shell villas or extensive civil rework can run 20–28 weeks. Flats needing only modular plus soft furnishing may finish in 8–10 weeks.

Speed without chaos requires: frozen designs, timely payments per agreed milestones, site access without other contractors conflicting, and builder-provided power and water. Royal Decor shares Gantt-style schedules at contract signing so everyone sees the same dates.

Festival deadlines — Poila Boishakh housewarming, pre-Puja move-in — are achievable when design starts eight to twelve weeks before your target date, not four. Rush fees and quality compromise are the hidden tax of late starts.
