Quick answer: A turnkey interior project for a new 2–3BHK apartment usually takes about 4 to 6 months from first meeting to handover — roughly 4–6 weeks for design and approvals, and 3–4 months for execution. At COZ Design Studio, the handover date is fixed in writing before work starts.
Why "how long will it take?" is the right first question
Most families doing interiors have a date in mind — a griha pravesh, a lease ending, children's school starting. A beautiful home delivered four months late still costs you rent, EMI and a lot of stress. That's why fixed timelines are the first thing we promise.
The six stages of a COZ Turnkey Solutions project
- Discovery — we learn how you actually live before we draw anything: light, habits, family, taste.
- Onboarding — layouts for every room, then 3D visualisation, so you see your home before anything is built.
- Design locking — material selections and a detailed BOQ (Bill of Quantities — every item, brand and rate), signed off together so the design and the budget are fixed.
- Pre-execution — the final team for your home is lined up and materials are ordered, all with proper paperwork and agreements in place.
- Execution — site supervision, with weekly site progress reports and photo updates, even when you can't be on site.
- Handover — quality check, snag list, final cleaning and a handover walkthrough, on the date we committed to.
What actually causes delays
In our experience, delays rarely come from the carpentry itself. They come from:
- Design changes after execution starts — one changed wardrobe can push three other trades.
- Slow decisions on materials, colours or appliances.
- Payment milestones missed, which hold up material orders.
- Builder-side issues — seepage, uneven floors or incomplete electrical lines discovered on site.
- Material lead times for imported or custom items.
How a fixed timeline works with COZ
We finalise the full design in 3D and lock the BOQ before execution starts. That's the single biggest reason timelines hold — there's no designing on site.
Your handover date is written into the agreement. To be fair to both sides, the timeline shifts if payments or client decisions are delayed — that's stated clearly upfront so there are no surprises later.
How you can keep your project on track
- Spend your thinking time in the 3D stage, not on site.
- Choose appliances early — the kitchen is built around them.
- Keep one family decision-maker for quick approvals.
- Plan payments around the agreed milestones.
