How much does 3BHK interior design cost in Kolkata?
A full turnkey 3BHK interior in Kolkata costs ₹18 lakh to ₹42 lakh for an apartment of 1,200–1,400 sq ft. Where you land in that range depends on the package you choose:
| Package | Cost for a 1,200–1,400 sq ft 3BHK |
|---|---|
| Budget | ₹18,00,000 – ₹21,60,000 |
| Premium | ₹21,60,000 – ₹30,80,000 |
| Luxury | ₹30,80,000 – ₹42,00,000+ |
On a per-square-foot basis, interior design in Kolkata runs from ₹1,500 to ₹5,000+ per sq ft depending on finish level and how much is custom-made.
A standard 3BHK takes 45 to 60 days to execute once the design is signed off.

Three real 3BHK projects and what they cost
Ranges are useful, but completed projects tell you more. These are our own:
| Project | Location | Final cost |
|---|---|---|
| 3BHK, Uniworld City | New Town | ₹18.5 lakh |
| 3BHK, PS NVyom | New Alipore | ₹32 lakh |
| 3BHK, Merlin Waterfront | Kolkata | ₹35 lakh |
The gap between ₹18.5 lakh and ₹35 lakh on similar-sized flats comes down to three things: how much furniture is custom-built rather than bought, the finish on the kitchen and wardrobe shutters, and how much false ceiling and lighting work is involved.
What is included in a 3BHK interior package
A turnkey 3BHK scope normally covers:
- modular kitchen with hardware and accessories
- wardrobes in all three bedrooms
- TV unit and living room storage
- false ceiling and lighting
- painting
- loose furniture where specified
- electrical and plumbing modifications within the flat
Commonly excluded and worth asking about before you sign: [CONFIRM — list your actual exclusions, e.g. civil/structural work, appliances, curtains, flooring replacement, complete rewiring].
Design revisions included: [CONFIRM].
Workmanship warranty: [CONFIRM — your cost page states one year, your homepage FAQ states ten years; these need to agree].
Room-by-room: where the money goes in a 3BHK
Rather than a flat per-room figure, it helps to understand what drives cost in each space.
Living room
The biggest visual return and usually the second-largest line item. Cost is driven by the TV unit’s size and finish, the false ceiling design, the lighting plan, and whether a feature wall involves veneer, fluting or stone.
Modular kitchen
Typically the single most expensive room. What moves the number:
- Carcass material — commercial ply versus BWP (boiling water proof) ply
- Shutter finish — laminate, acrylic, or veneer
- Hardware — soft-close hinges and channels, and the brand behind them
- Countertop — granite, quartz, or engineered stone
- Accessories — pull-outs, corner units, tall units
L-shaped and parallel layouts are the most common in Kolkata apartments because of typical kitchen proportions.
Master bedroom
Wardrobe size and shutter finish dominate. A bed back panel, dressing unit and lighting make up the rest.
Second and third bedrooms
Usually simpler. The third bedroom is where most Kolkata families make a choice: home office, children’s room, study, or guest room. Deciding this before design starts saves a costly change later.

Materials that survive Kolkata’s humidity
Kolkata’s climate is the single most underrated factor in an interior budget. High humidity for much of the year is hard on the wrong materials.
| Element | Budget option | Premium option | Humidity note |
|---|---|---|---|
| Kitchen carcass | Commercial ply | BWP / marine ply | BWP resists swelling in wet zones |
| Wardrobe shutters | Laminate | Acrylic or veneer | Laminate handles moisture well and costs less |
| Hardware | Standard hinges | Soft-close, branded | Poor hardware corrodes first in humid air |
| Countertop | Granite | Quartz | Both perform well; quartz needs less sealing |
| Flooring | Vitrified tile | Engineered wood, marble | Solid wood is a risk in Kolkata |
MDF is cheaper than plywood but far less forgiving around sinks, dishwashers and external walls. In a Kolkata kitchen the saving rarely justifies the risk.
What actually changes your 3BHK budget
Apartment size. A 900 sq ft 3BHK and a 1,500 sq ft 3BHK are different projects. Per-square-foot rates make comparison easier than headline totals.
How much is custom-built. Custom carpentry uses space better and costs more than bought furniture. Most budget overruns start here.
Finish level. The same wardrobe in laminate versus acrylic can differ by a large multiple with identical internal storage.
Civil and electrical changes. Moving a wall, relocating plumbing or rewiring adds cost that furniture-focused quotes often leave out.
Hidden costs buyers miss
The cheapest quotation is usually the least complete. Before comparing two numbers, check whether each one includes:
- hardware upgrades, or only base-grade fittings
- electrical modifications and additional points
- installation and transportation
- site protection and post-work cleaning
- painting after carpentry, not before
- GST
A quote that is 20% lower but excludes four of these is not cheaper.
Four mistakes that cost Kolkata homeowners money
Choosing on price alone. Compare scope line by line, not totals.
Skipping storage planning. A beautiful 3BHK with too little storage becomes cluttered within a year, and retrofitting is expensive.
Ignoring maintenance when picking materials. See the humidity table above.
Starting without drawings. Layout, electrical and furniture drawings signed off before work begins prevent the mid-project changes that cause both delays and budget overruns.
3BHK design ideas that work in Kolkata apartments
Full-height storage. Floor-to-ceiling wardrobes and overhead units add storage without taking floor area — valuable in apartments where circulation space is tight.
A restrained living room. Neutral bases, wood tones and warm layered lighting read as premium without premium spend. The cost sits in the lighting plan, not in the finishes.
The balcony as a real room. A green corner, a reading seat or a morning coffee spot. Among the cheapest square footage you will ever improve.
A kitchen built for maintenance. Moisture-resistant carcass, easy-clean shutters, real ventilation, and storage matched to how you actually cook.
A third bedroom that does two jobs. Work-from-home by day, guest room at night — a wall bed or sofa-cum-bed with a dedicated desk makes this practical rather than a compromise.
What to ask before hiring an interior designer
On the portfolio: can you show me completed 3BHK projects at my budget, with real photographs rather than renders?
On price: what exactly is included and excluded? Is GST extra? How many revisions do I get? What happens if I change my mind after production starts?
On execution: who manages vendors and site quality? What is the timeline, and what happens if it slips? What is covered by the warranty, and for how long?
A designer who answers these precisely is usually the one who will finish on budget.

A designer handles planning, materials, services and execution. A decorator focuses mainly on furnishing and styling an existing space.

Prioritize the kitchen, master bedroom and living room storage; keep the other rooms simpler; reduce custom carpentry where standard furniture works; and finalize the design before work starts.
