What does a 3BHK interior design actually cost in Delhi NCR? A room-by-room breakdown for 2026

"What does a 3BHK interior cost?" is the most asked question on any studio's first call. The honest answer is that it depends on seven variables — carpet area, level of customisation, scope (full-home or partial), material tier, hardware choices, whether you're starting from bare-shell or a builder fit-out, and how much structural or civil work the apartment needs. Two identical 3BHK floor plans in the same tower can finish ₹18 lakh apart, and both numbers can be defensible.

This guide is a room-by-room breakdown of what a 3BHK interior project actually costs in Delhi NCR in 2026, across three delivery tiers. All numbers below are ranges reflecting current market pricing — treat them as planning assumptions, not fixed quotes. The final number is always the one that comes out of a locked Bill of Quantities (BOQ), not a brochure.

A 3BHK cost range isn't a price — it's a planning envelope. Your actual number falls out of material specifications, hardware selections and scope. The job of the designer is to get you to a locked BOQ before civil work starts, not to hit a magic number at the first meeting.

The three tiers: Essential, Signature, Bespoke

Most Delhi NCR studios organise residential work into delivery tiers. The names vary; the structure doesn't. Here's how Re Room frames it, with indicative all-in ranges for a typical 1,500–1,800 sqft 3BHK:

The tier isn't just a budget label. It's a set of decisions: which rooms get custom joinery vs. standard units, which hardware brands, which finishes, how much lighting is designed vs. stock. Moving up a tier in one room — say, a Bespoke kitchen inside a Signature home — is normal and often the right call. Our packages page maps the three tiers to specific inclusions.

Room-by-room breakdown for a 1,500–1,800 sqft 3BHK

The table below is how a Signature-tier 3BHK project typically breaks out. Ranges assume a bare-shell to semi-finished starting point and exclude the cost of white goods, furniture you're buying from retail, and any structural civil work beyond minor modifications.

Add the midpoints and a Signature 3BHK lands around ₹22–24 lakh all-in. Strip the kitchen down to Essential and drop one bedroom's wardrobe to a stock unit and you're at ₹16–18 lakh. Move the kitchen up to Bespoke with veneer shutters and imported hardware and add a designed lighting scheme and you're at ₹30–34 lakh.

Our dedicated 3BHK Interior Design service page has a fuller breakdown of inclusions per tier and how we lock BOQ before execution.

What pushes cost up

The variables that consistently move a 3BHK project north of the mid-range:

• Imported veneers and stone. Walnut, Italian marble, bookmatched surfaces — can add ₹1.5–4 lakh per room where used.
• High-end hardware. Hafele premium, Blum Aventos lift systems, motorised blinds — budget a 20–35% premium over mid-range Hettich/Hafele.
• Designed lighting schemes. Layered lighting (ambient, task, accent, decorative) with specified fixtures typically adds ₹1.5–3.5 lakh over a stock fit-out.
• False ceiling across the whole home. Full-home gypsum with cove, profile and spot lighting: ₹3–5 lakh vs. ₹1.8–3 lakh for living + master only.
• Civil modifications. Wall removal, toilet relocation, new electrical runs — ₹80k–3 lakh depending on scope, plus society NOC timelines.
• Designer furniture, specified. Specifying dining tables, sofas, beds and chairs rather than buying from retail: 25–80% premium, plus 6–10 week lead times.

What brings cost down — sensibly

Not all cost reduction is equal. Some choices shave budget without hurting the outcome. Others create regret within 18 months:

• Retain existing flooring if it's in good condition. Saves ₹2–4.5 lakh on a 3BHK and has no design-life impact if the tile or vitrified finish is sound.
• Split tiers by room. Bespoke kitchen + Signature bedrooms + Essential utility areas is a more defensible spend than spreading Signature evenly.
• Stock wardrobes for the kids' room. A ₹45–70k stock wardrobe behaves indistinguishably from a ₹1.8 lakh custom one for a 9-year-old. Revisit in five years.
• Retail furniture for the dining set. Unless you want a specified piece, retail 6-seater dining sets at ₹55k–1.1 lakh cover most Signature-tier homes well.
• Phase the bathrooms. If two of the three bathrooms are recent-builder-standard and functional, refresh one now, revisit in 3 years.

What we don't recommend cutting: hardware grade in the kitchen, false-ceiling work in the master bedroom once it's planned, or the project-management fee. Those three are the places shortcuts show up inside 12 months.

The hidden costs most quotes don't show

The gap between "studio A's quote" and "studio B's quote" for the same 3BHK is often not what it appears. Before comparing headline numbers, check whether each quote includes:

• GST. 18% on most line items. A ₹18 lakh ex-GST quote is ₹21.2 lakh paid.
• Electrical rewiring / additional points. New lighting schemes often need 20–40 new points at ₹350–650 each.
• Plumbing upgrades. Shifting a washing machine line or adding a hot-water outlet isn't free.
• Hardware specifications, named. "Soft-close hardware" means nothing. "Hettich Sensys hinges, Blum Movento drawers" is a specification.
• White goods and appliances. Hob, chimney, oven, dishwasher — check whether they're in the quote or "to be procured by client."
• Society charges and loading/unloading. Some societies in Gurugram and Noida charge ₹15k–40k for move-in and shift work.
• Project management fee structure. Is it bundled into line items, shown separately, or absent entirely (which usually means it's hidden in marked-up materials)?
• Defect liability period and warranty. Post-handover fixes — what's covered, for how long, at whose cost.

How to compare two 3BHK quotes fairly

When you have two or three studio quotes in front of you, the headline number is almost always misleading. Here's a method that works:

1. Normalise to scope. Make a single spreadsheet with every room on rows and inclusions on columns. Fill in what's in each quote. The gap is usually in what one quote excludes, not in what both include.
2. Match hardware and material specs. Ask both studios to specify brand + series for hinges, sliders, laminates, plywood grade, countertops. "Standard plywood" is not a spec; "Century Ply Architect Ply" is.
3. Check the design + PM fee explicitly. Either it's a line item or it's embedded in markups. Embedded is fine — but ask the studio to tell you, in writing, what percentage it is.
4. Add GST uniformly. If one quote is ex-GST and the other inclusive, you're not comparing like-for-like.
5. Ask each studio to commit the quote as a BOQ. If one says "this is a BOQ we'll lock before civil work starts" and the other says "this is an estimate, final numbers during execution" — the BOQ quote is almost always the cheaper real outcome even if it's higher on paper.

Our companion post on 8 questions to ask an interior designer in Delhi goes deeper on the BOQ question — it's the single most important one in this whole framework.

BOQ lock and budget certainty

Re Room's model on every residential project is the same: we brief, concept, design-develop, then issue a line-item BOQ. Sign-off on the BOQ is the start of execution. Nothing changes after that without a written change order, with cost and timeline impact noted. The BOQ is the number we deliver on.

This is why our Signature-tier 3BHK projects typically finish within 3% of the BOQ number even on six-month timelines. It isn't magic — it's the discipline of not quoting a number we don't believe we'll hit.

If you're working through 3BHK budgets and want a written view on where yours realistically lands before you commit to any studio, book a Home Brief. One hour, one senior designer, written summary back in 48 hours, no obligation.

All costs in this post are planning ranges based on current Delhi NCR market pricing as of April 2026. Actual quotes will vary based on your specific scope, specifications, site conditions and timing. Treat these numbers as planning assumptions, not fixed prices.
