Planning interiors for a 3BHK flat in Delhi NCR is exciting—but it can also feel confusing when it comes to budgeting. Homeowners often ask:
“How much will interiors really cost?”
“Where is my money going?”
“What can I save on without compromising quality?”
In this 2026 guide, we break down the actual interior design costs for a 3BHK flat—room by room—so you can plan smartly, avoid surprises, and make informed decisions.
At Rethink Designing, transparency is core to how we work. Let’s break it down.
Average Interior Cost for a 3BHK Flat (Delhi NCR – 2026)
For a standard 3BHK flat (1200–1600 sq. ft.), interior costs typically fall into three ranges:
Basic Interiors: ₹8–12 lakhs
Mid-Range Interiors: ₹13–18 lakhs
Premium Interiors: ₹20–30+ lakhs
The final cost depends on scope of work, material choices, finishes, and level of customization.
Detailed Cost Breakdown (Room-Wise)
1. Modular Kitchen (₹2.5 – ₹6 lakhs)
The kitchen is one of the most investment-heavy spaces.
Cost depends on:
Layout (L-shape / Parallel / U-shape / Island)
Cabinet material (BWP plywood recommended)
Finish (Laminate / Acrylic / PU)
Hardware & accessories (soft-close, pull-outs, tall units)
Countertop (Granite / Quartz)
Smart Tip:
A factory-finished modular kitchen costs more upfront but saves money long-term due to durability and minimal maintenance.
2. Wardrobes (₹2 – ₹4 lakhs)
Typically includes wardrobes for 3 bedrooms.
Cost varies based on:
Sliding vs hinged shutters
Internal fittings (drawers, pull-downs, organizers)
Finish (laminate, glass, mirror panels)
Smart Tip:
Avoid over-customisation inside wardrobes. Functional layouts reduce cost without affecting usability.
3. Living Room Interiors (₹1.5 – ₹3 lakhs)
Includes:
TV unit
Decorative wall paneling
False ceiling with lighting
Storage or display units
This is where design aesthetics matter most.
4. Bedrooms (₹2 – ₹4 lakhs total)
For 3 bedrooms combined:
Bed back panels or headboards
Side tables
False ceiling & lighting
Study or dresser units
Master bedroom usually consumes the highest budget due to premium finishes.
5. False Ceiling & Lighting (₹1 – ₹2.5 lakhs)
Includes:
Gypsum false ceiling
Cove lighting, spotlights, profiles
Drivers and wiring
Lighting design has a huge impact on how premium your home feels—even with moderate finishes.
6. Electrical, Plumbing & Civil Work (₹1 – ₹2 lakhs)
Often overlooked but critical:
Electrical rewiring as per design
Additional plug points
Minor civil changes
Poor planning here leads to rework—one of the biggest hidden costs.
7. Paint, Wallpaper & Finishes (₹80,000 – ₹1.5 lakhs)
Interior wall paint
Texture walls or wallpapers
Polish or accent finishes

Why Costs Vary So Much Between Homes
