3BHK Interior Design Cost in Chennai | Complete Turnkey Pricing Guide
Planning the interior budget for a 3BHK flat in Chennai requires understanding scope, material grades, and execution standards. At Interiors by DeX, our complete turnkey 3BHK apartment interiors start from ₹12 Lakhs. This comprehensive package covers end-to-end execution—modular kitchen with quartz countertop, multiple bedroom wardrobes with lofts, living TV entertainment panelling, false ceiling, architectural cove lighting, electrical works, and selected civil modifications with our signature 5-year replacement guarantee.
Understanding 3BHK Interior Cost Factors in Chennai
A typical 3BHK flat in Chennai ranges between 1,200 sq ft and 1,800 sq ft. The cost of execution depends primarily on three factors:
Core Board Specifications: We exclusively use certified 100% Boiling Waterproof (IS 710 BWP) marine plywood for wet zones (kitchen and vanity) and calibrated moisture-resistant boards for dry areas.
Shutter & Surface Finishes: Anti-scratch acrylic, seamless high-gloss PU lacquer, and anti-fingerprint laminates.
Architectural Lighting & Hardware: Soft-close Blum/Hafele runners and integrated cove LED false ceilings that define living zones.
What is Included in DeX's 3BHK Turnkey Interior Scope
Our ₹12 Lakh starting turnkey package delivers a fully finished, move-in-ready 3BHK residence:
Modular Kitchen: Factory-machined base and overhead cabinets in IS 710 BWP marine ply, quartz countertop, SS sink integration, soft-close tandem boxes, and bottle pullouts.
Master Bedroom Suite: Full-height 3-door or 4-door wardrobe with integrated loft storage, internal organizers, and sleek dressing mirror console.
Second & Third Bedrooms: Custom wardrobes with lofts, soft-close hinges, and integrated work-from-home study desks with bookshelves.
Living & Foyer Areas: Floating TV entertainment wall unit with fluted or acoustic paneling, concealed shoe rack, and foyer divider.
Electrical & False Ceiling: Complete gypsum false ceiling across hall and dining with concealed LED strip lighting and electrical point shifting.


Why Low-Cost Estimates End Up Costing More
Many Chennai contractors quote deceptively low rates (₹4L to ₹6L for a 3BHK) to win projects, only to introduce cost escalation later:
Material Substitution: Using cheap Commercial MR plywood that swells and rots during Chennai monsoons.
Excluded Scope: Omitting quartz countertops, kitchen accessories, false ceilings, electricals, and post-work cleaning.
Hand-Glued Edge Banding: Manual tape application that peels within 12 months, compared to DeX's factory PUR edge-bonding.
Zero Post-Handover Warranty: Independent carpenters vanish after final payment. DeX provides a written 5-year replacement guarantee.
