Complete Turnkey Interior: What Is Included?
What does turnkey interior design actually include? A transparent breakdown for West Bengal homeowners — design, civil, modular, MEP, finishes, and what is usually extra.

"Turnkey interior" appears on every hoarding from Rajarhat to Haldia — but scope varies wildly between firms. One quote includes painting and false ceiling; another stops at modular installation and leaves you hunting electricians during move-in week.
Royal Decor Interior Designer publishes detailed scope documents because clarity prevents disputes. This guide explains what our complete turnkey package typically includes for residential flats and villas in West Bengal — and what items remain client-supplied or optional upgrades — so you budget the full picture before signing.
Turnkey means one team, one schedule, one accountable handover — not a vague promise.
Design and project management
Turnkey starts with site measurement, layout planning, 3D visualisation, material selection support, and consolidated quotation. A dedicated project manager coordinates trades, weekly updates, and snag closure — you are not WhatsApping five different contractors.
Design revisions are included within agreed rounds before production freeze. Changes after freeze are documented as variations with cost and timeline impact — never sneaked in silently.
- 3D renders for kitchen, wardrobes, key living zones
- Electrical and lighting layout drawing
- Material board with approved laminates, tiles, paint codes
Civil and wet-area work
Typical turnkey scope covers demolition of existing finishes where needed, electrical chasing and conduit, plumbing modifications, bathroom waterproofing and tiling, kitchen tiling, false ceiling with gypsum, and wall preparation plus painting.
Structural wall removal requires separate structural engineer approval — not silently bundled. We flag load-bearing constraints during first site visit.
Modular and built-in furniture
Kitchen base and wall units, tall pantry, wardrobes, TV units, study tables, and entry shoe storage are factory-built to approved drawings. Soft-close hardware, branded hinges, and specified board grades are part of scope — not surprise upgrades.
Loose furniture — sofas, beds, dining tables — may be included in premium turnkey packages or procured separately. Royal Decor itemises which category your quote falls into.
MEP, fixtures, and finishing trades
Electrical fitting of lights, fans, switches, and major appliances as per drawing. Plumbing installation of sinks, WC, basins, and shower fixtures supplied under contract. Chimney ducting, AC copper line concealment coordination, and door hardware installation typically included.
Glass shower panels, mirrors, curtain rods, and decorative-only items are often optional lines — we mark them clearly on quotations.
Final cleaning, handover walkthrough, and snag-list closure within agreed days are part of professional turnkey — not "we left keys at security" handovers that leave touch-up paint and loose handles for you to chase.
Exclusions and client responsibilities
Common exclusions: major structural civil, society liaison fees, appliance purchases (fridge, washing machine), movable décor, and deep cleaning beyond standard handover wipe-down. Government taxes, parking permissions, and lift protection deposits vary by building.
Client timely decisions and milestone payments keep turnkey on schedule. Delayed tile selection stalls tiler, plumber, and painter alike — turnkey is a partnership, not magic.
Warranty terms should be written: typically 5–10 years on modular carcass and hardware from reputable firms, shorter on paint and civil depending on scope. Royal Decor provides handover folders with product codes, contact numbers, and care instructions — turnkey means documented aftercare, not just keys.
How turnkey differs from modular-only packages
Modular-only quotes cover factory furniture installation — kitchen, wardrobes, TV unit — on a finished site you prepared elsewhere. Turnkey assumes responsibility for everything needed before modules land: chased wiring, levelled walls, painted surfaces, and tiled wet areas.
Homeowners choosing modular-only often underestimate civil coordination — five contractors with no single schedule frequently costs more in calendar time than turnkey savings on paper. Compare total weeks to possession, not just carpentry line items.
