3BHK Interior Cost in Chennai
Planning interiors for a 3BHK in Chennai? We explain the costs involved in premium modular kitchens, wardrobes, and false ceilings.
1. What a 3BHK interior actually costs in Chennai
A 3BHK budget moves with carpet area far more than with taste. The table below splits a standard-specification fit-out across the three apartment sizes most common in Chennai. Chennai runs about 5% above Hyderabad on the same specification, and coastal humidity makes BWP/IS 710 and SS 304 hardware non-optional rather than an upgrade.
| Work category | 1,400 sq ft | 1,800 sq ft | 2,400 sq ft |
|---|---|---|---|
| Modular kitchen (carcase, shutters, basic accessories) | ₹2.9–3.4 lakh | ₹3.6–4.2 lakh | ₹4.7–5.8 lakh |
| Bedroom wardrobes (3 rooms, lofts included) | ₹3.7–4.4 lakh | ₹4.7–5.5 lakh | ₹6.3–7.9 lakh |
| Pooja, foyer & TV units (living & family rooms) | ₹1.3–1.6 lakh | ₹1.9–2.3 lakh | ₹2.9–3.7 lakh |
| False ceiling & cove lighting (gypsum board) | ₹1.1–1.4 lakh | ₹1.5–1.9 lakh | ₹2.1–2.7 lakh |
| Electrical & plumbing (extensions, point shifts) | ₹0.5–0.7 lakh | ₹0.8–1.2 lakh | ₹1.3–1.7 lakh |
| Wall finishes (premium painting, wallpaper accents) | ₹0.9–1.3 lakh | ₹1.3–1.6 lakh | ₹1.7–2.3 lakh |
| Miscellaneous & contingency (GST, transport, snags) | ₹1.6–2.1 lakh | ₹2.2–2.8 lakh | ₹3.2–4.2 lakh |
| Estimated total | ₹12.0–14.9 lakh | ₹16.0–19.5 lakh | ₹22.2–28.3 lakh |
Basis: AlcorOne execution rates as of , exclusive of GST. Derived from our Hyderabad execution rates at the Chennai differential of about +5% described above. Indicative range for planning; the binding figure comes from an itemised BOQ against the actual site measurements and specification.
The ₹16–26 lakh headline band quoted at the top of this guide describes the typical 1,800–2,400 sq ft Chennai 3BHK. A compact 1,400 sq ft unit lands below that band, and a 2,400 sq ft flat specified to the top of every line above can run past it. Read the column that matches your actual carpet area rather than the headline.
Which line moves most
Wardrobes and kitchen together account for roughly half the budget at every area, and they are also the two categories where hardware grade — not appearance — drives the spread inside each range. The low end of each cell assumes BWR ply with soft-close hardware; the high end assumes BWP/IS 710 carcase in wet zones with tandem drawer systems.
2. What Chennai quotes commonly exclude
A 3BHK has more rooms for an exclusion to hide in. Contractor A quotes ₹16 lakh, Contractor B quotes ₹20 lakh, and A looks like the better deal — until you request a detailed Bill of Quantities and find the two are not comparable documents.
What gets left out of an attractive quote
| Often excluded | Typical additional cost if added later |
|---|---|
| Electrical modifications (new points, rewiring) | ₹26,000–₹63,000 |
| Civil work (wall breaking, plumbing shifts) | ₹16,000–₹53,000 |
| False ceiling changes/additions | ₹42,000–₹1,26,000 |
| Quartz/granite countertops (vs. laminate) | ₹32,000–₹84,000 |
| Kitchen appliances (chimney, hob) | ₹42,000–₹1,58,000 |
| Premium hardware upgrade | ₹21,000–₹74,000 |
| GST (18% on services) | Often 10–18% of contract value |
| Transportation and logistics | ₹5,000–₹16,000 |
| Site protection during work | ₹5,000–₹11,000 |
Add even half of these to a low base quote and it quietly reaches the figure the higher quote named at the outset — except now you are negotiating extras mid-project, with far less leverage than you had before signing.
How to actually compare two Chennai quotes:
- Request a line-item BOQ from every contractor, not a lump-sum figure.
- Check whether GST is included or added separately.
- Confirm whether electrical and civil work are in scope or excluded.
- Ask what hardware brand and grade is specified — “hardware included” can mean a ₹200 hinge or a ₹1,200 hinge.
- Confirm the area basis in writing: carpet area and built-up area on the same flat can differ by 20–25%.
3. The Cost of Coastal Engineering
When budgeting for 3BHK Interior Cost in Chennai, standard pricing models don't always apply. The city's intense heat and coastal humidity mean that cutting corners on core materials will cost you heavily in repairs within a few years. We strongly advise allocating your budget toward IS 710 Boiling Water Proof (BWP) marine plywood and strictly SS 304 grade stainless steel hardware.
4. Where to Spend vs. Where to Save
Invest your money in the structural skeleton of your home. High-suction chimneys, waterproof base cabinets, and insulated false ceilings (to combat Chennai summers) are non-negotiable. You can save money by opting for high-quality laminates in dry areas instead of expensive PU or acrylic finishes.
5. Transparent BOQ
Often, initial low quotes in Chennai exclude essential protective treatments, like anti-termite bases and SS hardware upgrades. At AlcorOne, our Bill of Quantities (BOQ) is 100% transparent. You will see exactly what grade of plywood and hardware is going into your 3BHK Interior Cost project before any work begins.

What the warranty actually covers
A cost figure is only half the question; the other half is what happens after handover. AlcorOne's warranty on interior work in Chennai runs in three tiers, stated separately because they cover different things and expire at different times — a single headline figure would misrepresent all three.
| Tier | Term | What it covers |
|---|---|---|
| Carcass — plywood | 10 years | Delamination, borer attack and manufacturing defect in the board of modular kitchens, wardrobes and fixed joinery built by AlcorOne. Conditional on the board grade specified in the signed BOQ being the grade supplied and installed — BWP to IS 710 in wet zones, BWR to IS 303 above splash lines. This tier covers the board itself and nothing else. |
| Installation and workmanship | 1 year | Defects attributable to how the work was built and fitted — alignment, levelling, fixing, edge-banding and similar. |
| Hardware, fittings and appliances | Manufacturer's own term | Hinges, channels, drawer systems, electricals, sanitaryware and appliances carry the vendor's own warranty — Hettich, Blum, Häfele and Ebco each publish their own mechanism terms. AlcorOne registers that documentation in the client's name at handover and facilitates the claim. |
Not covered under any tier: water ingress originating from base-building or plumbing defects outside AlcorOne's scope; damage from misuse, unauthorised modification, or third-party work carried out after handover; and normal wear to finishes. The full terms are on the Terms of Service page.
Read a headline warranty number in this category the same way. A ten-year figure quoted on its own is almost always the carcass tier alone, with installation sitting at one to two years beneath it. Ask any contractor which of those years are theirs and which are the brands'.
Frequently asked questions.
Does the cost include SS 304 hardware?
Yes, in Chennai, we consider SS 304 rust-proof hardware mandatory. It is included in our standard premium pricing.
Why is interior work more expensive in coastal areas?
The constant salt air requires specialized materials like BWP marine plywood and stainless steel hinges, which have a slightly higher initial cost but prevent premature rotting and rust.
Who produces the design and 3D visualisation?
AlcorOne is an execution-first contractor, so design is produced by our partner architects, designers and consultants rather than an in-house studio. If you already have drawings from your own architect we build to them and there is no design charge at all. If you need drawings, we introduce a partner and their fee appears as its own line in the BOQ, so you can see exactly what is design and what is execution.
What warranty does AlcorOne give on its interior work?
Three tiers, stated separately because they cover different things and expire at different times. Ten years on the plywood carcass from the date of handover, against delamination, borer attack and manufacturing defect in the board — conditional on the grade specified in the signed BOQ being the grade supplied and installed. One year on installation and workmanship: alignment, levelling, fixing, edge-banding and similar. Hardware, fittings and appliances carry the manufacturer's own term, and AlcorOne registers that documentation in the client's name at handover and facilitates the claim. Not covered under any tier: water ingress originating from base-building or plumbing defects outside AlcorOne's scope; damage from misuse, unauthorised modification, or third-party work carried out after handover; and normal wear to finishes.
