Diwali Interior Offer in Chennai: 25% Off Plus a Free Upgrade

Somewhere between scrubbing the pooja room and hunting for the good diyas, most of us do the same thing every Diwali: we actually look at our homes. The wardrobe door that never shuts properly. The TV wall with a tangle of wires behind it. A kitchen that made sense ten years ago and doesn't now.

Interiors by DeX is running a Diwali offer from 29 October to 16 November 2026 for exactly that moment. This blog lays out what it includes, how to choose the free upgrade, and what to check before you say yes to any festive offer, ours included.

The Diwali offer at a glance

Terms and conditions apply. Your written quote is the final word on what is included, so read it line by line.

What 25% off modular interiors means in practice

Modular interiors are units built in a factory and fitted at your home: the kitchen, the wardrobes, the TV unit, the storage. That is different from carpentry cut and assembled on site. Our pricing guide explains the trade-off. Factory production means less wastage, while on-site work needs more specialised labour and usually costs slightly more.

So the 25% applies to that modular scope. On every ₹1 lakh of modular work in your quote, that is ₹25,000 off. Anything that is not modular, such as civil changes or items outside the proposal, is quoted as usual.

For context, the same pricing guide gives indicative starting points of ₹9 lakh for a 2BHK and ₹12 lakh for a 3BHK, both plus GST. The offer is for home interiors of ₹13.5 lakh and above. If you are not sure whether your project clears that mark, ask during the free consultation and site measurement. We will tell you where you stand before you decide anything.

Which free upgrade should you pick?

You get one. Here is how we would think about it.

The wardrobe (worth ₹1,29,999)

Pick this if storage is the thing your household argues about. It is the largest value on the list, and bedrooms in Chennai flats often do not get enough of it. Before you decide, count the wardrobes in your plan and ask three questions. What will the inside hold: shelves, drawers, a loft? Do the doors slide or swing in that particular room? And what board is the body made of? In a humid city that last one matters, and our piece on particle board vs MDF explains the difference.

Lighting (up to ₹1 lakh)

Lighting changes how a home feels more than most furniture does, and you notice it every single evening. A good plan layers it: soft ambient light, brighter light where you cook or read, and small accents on shelves or the TV wall. Warm white, around 2,700 to 3,000 K, suits living spaces at night. Dimmable circuits earn their keep during Diwali, when diyas and string lights are doing half the work. Our guide to house lighting design goes room by room.

Home automation (up to ₹1 lakh)

The poster shows a wall panel, so let us be practical about it. Automation is easiest when it is planned together with the electrical layout, before the false ceiling and panelling go up. Spare conduits and switch positions are cheap to decide early and expensive to reopen later. Legrand India's guide to wired and wireless systems makes the same point, and suggests wireless setups for apartments. Start with lighting scenes, one touch for "guests" and another for "movie night", and add curtains or locks only if you will really use them. Ask what the ₹1 lakh covers, room by room and device by device, and get it in writing.

Not sure? Ask yourself which of the three you would cut first if the budget got tight. Pick that one.

Diwali Week at the Experience Centre: 1 to 8 November

During Diwali Week, the Experience Centre carries an extra layer on top of the main offer: complimentary products worth up to ₹1,29,999 and a 22k, 1 gram gold coin to take home, along with the flat 25% off on home interiors.

The Experience Centre is on the first floor of MOTI Towers, 131/9, Rajiv Gandhi Salai, Perungudi, Chennai, 600096.

It is open Tuesday to Sunday, 11 am to 8 pm, for walk-ins and appointments.

Walking in helps because you can see finishes, modular formats, kitchen layouts and storage ideas in person instead of squinting at a screen.

Bring your floor plan, a few photos of the rooms, and a short list of what you cannot live without. Deepavali falls on Sunday, 8 November, so if you want to come during Diwali Week, earlier in the week is easier than the last day.

Before you say yes to any festive offer

A discount is only as good as the quote behind it. Whoever you buy from, check these.

1. What is discounted. The whole project, or only the modular work?

2. What the free item is and what it is worth. Which one do you get, and can you choose?

3. The warranty, on paper. Ours is 15 years on modular products, with free replacement in the first 5 years. Ask any other company for its terms in writing.

4. The payment schedule. Ours is 10% at confirmation, 50% on design completion and 40% on material delivery.

5. The dates and eligibility. When does the offer end, and what minimum project value does it need?

6. An itemised quote. Without one, you cannot compare two offers fairly.

What booking this month means for your handover

Our published timelines are 35 days for a modular kitchen and wardrobes, and for a full home, 45 days for a 2BHK, 60 for a 3BHK, 75 for a 4BHK and 90 for a villa. The first three days are consultation and site measurement, and days 4 to 10 are design and approval.

Do the sums from your own start date. A 60-day 3BHK that starts on 16 November finishes in mid-January, around Pongal. If a festival is your deadline, say so in the first meeting and ask for a dated schedule.

One Chennai note. The India Meteorological Department says the northeast monsoon rainfall began over Tamil Nadu on 15 October 2026. It is a good season to ask how materials are stored on site and how boards are protected from moisture.
