3BHK · 1500–1800 sq ft
3BHK interior cost for 1500–1800 sq ft homes
A 3BHK of 1500–1800 sq ft has the room for details that smaller homes skip: a walk-in dresser, a family lounge corner, generous balconies and sometimes a study or servant room. Owners at this size are often upgrading from a previous apartment and know what they want, so the brief tends to focus on material quality, lighting and a few well-judged statement pieces.

Good to know
How we arrive at these numbers
Large 3BHKs are common in premium high-rises along OMR and ECR, and in upscale central pockets such as Adyar, Alwarpet and Nungambakkam where older buildings have big rooms.
In sea-facing or near-coast homes on ECR and in Besant Nagar or Thiruvanmiyur, salt-laden air can corrode cheaper hinges and channels, so stainless or coated hardware from partners like Hettich is a sensible choice near balconies.
Since the totals are the same as a mid-size 3BHK, the per-sq-ft rate falls to around ₹230/sq ft – ₹430/sq ft on Premium at 1650 sq ft, leaving room to upgrade finishes in key rooms.
Bigger living rooms here can take a full-wall TV and storage unit, a bar or display cabinet and a separate seating corner, which are the usual drivers toward the upper end of each range.
Many large 3BHKs include a study or extra room; planning built-in shelving and a desk there often replaces the need for a separate home office elsewhere.

Five ways to keep your budget on track
- 01
Upgrade where you touch daily
In a large home, spend on kitchen drawers, wardrobe hardware and switches that see daily use. Decorative panelling in rarely used rooms can stay simpler.
- 02
Create a walk-in dresser if space allows
Large master bedrooms or a dress area near the bathroom can become a walk-in with open shelves, drawers and a full-length mirror. Plan ventilation to keep clothes fresh in humid months.
- 03
Plan lighting as a system
With larger rooms, combine ceiling, cove, profile and accent lighting on separate circuits. Deciding this before carpentry avoids cutting finished panels later.
- 04
Protect finishes near balconies
Large balconies bring light but also rain splash and salt air in coastal areas. Choose laminates and hardware rated for moisture near balcony doors, and avoid veneer close to openings.
- 05
Keep one room flexible
Leave the study or third bedroom adaptable with modular shelving and a daybed, so it can evolve from guest room to office or hobby room over the years.

FAQ
Common cost questions
Still unsure? Our designers are happy to answer anything on a call.
Why is the cost range the same as a smaller 3BHK?
The number of rooms and units is often similar, so the base estimate stays the same while the per-sq-ft rate drops. In practice, larger homes tend to add features like walk-ins or bar units, which move the final quote within or above the range.
What hardware works best near the sea in Chennai?
Stainless or coated hinges, channels and handles resist corrosion better in salt air. Partner brands like Hettich offer options suited to humid, coastal conditions. Your designer can suggest where these are worth using.
Is a walk-in wardrobe practical in an apartment?
In a 1500–1800 sq ft 3BHK, it can be if the master bedroom has a dress area or a spare corner. It needs good lighting and ventilation to avoid mustiness in the monsoon.
Should I hire a designer for only some rooms?
You can, but designing the whole home together keeps materials and lighting consistent. Many owners finalise the full plan and then execute in phases.
How do I avoid the home feeling over-designed?
Limit feature walls to one or two areas, keep a restrained palette and let good lighting do the work. Large rooms look calm when storage is concealed and surfaces are uncluttered.
