A 3BHK in Coimbatore is typically 10-14 windows plus 1-2 balcony doors. Project value usually lands between ₹1.5 lakh and ₹4 lakh depending on spec. It's a meaningful renovation — not trivial like a one-room job, not overwhelming like a villa. Plan it for the long weekend you'll be willing to dedicate to it.
3BHK projects break down as: master suite (2 windows + sometimes a small balcony), two more bedrooms (1-2 windows each), living-dining (2-3 windows + main balcony slider), kitchen (1 window), 2-3 bathrooms (1 ventilator each), sometimes a utility window. Total: 10-15 openings. Replacement work is the default. Manufacturing 10-14 days, installation 3-5 working days. Total project: 18-24 days from order to last window installed.
" 3BHK is the project size where premium spec starts to make sense. You can afford to put double-glazing where it matters without compromising other rooms.
In a 3BHK, the master bedroom (and its attached balcony if there is one) is the room where comfort upgrades pay off most directly. You spend 6-8 hours a day there. Double-glazing for noise, tilt-and-turn for upper-floor convenience, premium hardware for quiet operation — these earn their cost in the master suite in a way they don't in a guest bedroom that gets used twice a year.
If one of the three bedrooms is for a child, the safety considerations are real. Lockable handles that the child can't accidentally open, position of any opening sashes (children pull on whatever's accessible), grill design where it doesn't feel prison-like. These are details we discuss at measurement. The default safety spec is usually a casement window with restricted opening angle or a sliding window with a child-lock catch.
Many 3BHK floor plans nominally have three bedrooms but the third is used as a study, home office, or guest room. The windows for this room should be spec'd for its actual use, not for theoretical bedroom use. Home offices benefit from good natural light (larger glazing) and quiet (double-glazing if there's road noise). Guest rooms can be spec'd minimum because they're rarely used.
3BHK customers often ask whether to do it in two phases — bedrooms first, common areas second. Both approaches work, but doing it in one phase usually costs 8-12% less because the mobilisation overhead spreads across more windows. The reason to phase is cash flow, not project quality. If you can afford to do it all at once, do it all at once. The unified look across all rooms is meaningful.
Another common conversation is around colour choices. In a 3BHK, the temptation is to vary the colour — modern grey in one bedroom, classic white in another, woodgrain in the living area. Resist. The visible windows from outside the building should match each other for the building elevation to read cleanly. Interior face colours can vary if you really want, but exterior colour consistency is the default best practice.
The third common question is about budget allocation across rooms. Rough guide: master suite 30-35%, living-dining and balcony 30-35%, second and third bedrooms 15-20%, kitchen and bathrooms 10-15%. This reflects where the value really lands. If you're under budget pressure, the right cuts are second-bedroom premium features and bathroom ventilator spec upgrades — not master-suite quality.
3BHK measurements typically take 2-3 hours including room-by-room discussion. We document each opening and your specific concerns per room.
We often send two quote versions: 'standard spec' (typical mid-range across all rooms) and 'priority spec' (premium for master suite and living, standard elsewhere). Choose between them or mix.
10-14 days. We typically batch the manufacturing by room so installation can be done in a logical sequence.
Bedrooms first (so you can sleep in them through the rest of the work), then living-dining, then balcony door, then bathrooms last (least disruption).
