Interior Renovation Cost Guide for Delhi NCR Flats (3BHK–5BHK)
Published 10 June 2026 · 7 min read
One of the first questions any homeowner asks before starting an interior renovation is simple: what will it actually cost? The honest answer is "it depends" — but it depends on a specific, predictable set of factors. Here's how those factors played out across our own completed projects in Ghaziabad, Noida and Gurugram.
What Actually Drives the Number
- Unit size and layout — a 3BHK and a 5BHK aren't just "more of the same"; larger units usually mean more custom carpentry, more electrical points, and more finish area.
- Scope: renovation vs. full turnkey — renovating an existing flat's finishes costs less than a full turnkey fit-out of a bare independent floor, which includes civil, MEP and interior from scratch.
- Material grade — laminate vs. veneer vs. solid wood; vitrified tile vs. natural stone; these choices alone can shift a budget by 30–50%.
- Furniture type — modular vs. loose wooden/steel furniture changes both cost and lead time.
- Society access rules — work-hour restrictions and material-movement rules in gated societies can extend timelines, which indirectly affects labour cost.
Real Numbers From Completed Projects
| Project | Unit Type | Location | Value | Duration |
|---|---|---|---|---|
| Apex The Kremlin | 3BHK | Ghaziabad | ₹20 lakh | ~3 months |
| T&T Society | 4BHK | Ghaziabad | ₹32 lakh | ~4 months |
| Gaurs Siddhartham | 4BHK | Ghaziabad | ₹40 lakh | — |
| Samridhi Grand Avenue | 4BHK | Noida | ₹50 lakh | ~4 months |
| Civitech Stadia | 5BHK | Noida | ₹65 lakh | ~6 months |
| Independent Floor (Advocate) | Independent Floor | New Delhi | ₹80 lakh | ~6 months |
| Independent Floor (Business Owner) | Independent Floor | Gurugram | ₹1.2 crore | ~12 months |
Notice the pattern: cost tracks unit size and scope far more than it tracks location. A 4BHK renovation in Ghaziabad and a 4BHK renovation in Noida landed in a similar band once you account for material choices.
How to Get an Accurate Estimate for Your Flat
- Have a contractor visit and measure the actual space — carpet area alone doesn't tell the full story.
- Decide renovation vs. full turnkey scope upfront.
- Pick a material grade band (economy / mid / premium) before asking for quotes, so estimates are comparable.
- Ask for a written scope-of-work with the quote, not just a lump sum.
