A 3BHK is usually the family house — the one built to live in for decades — and that changes how the budget behaves. The structure costs roughly the same per sq ft as a smaller house; what pushes 3BHK budgets up is the third bathroom, the larger tiled areas and the finishes. This guide separates the two.
How Big Is a 3BHK?
| Layout | Typical built-up area |
|---|---|
| Single-floor 3BHK | 1,300 – 1,600 sq ft |
| Duplex 3BHK (two floors) | 1,600 – 2,000 sq ft including staircase |
| 3BHK on a 200 sq yard plot (one floor) | about 1,200 – 1,300 sq ft after setbacks |
A comfortable single-floor 3BHK has three bedrooms of 10–12 ft by 11–13 ft, a hall, a kitchen, dining, three toilets (two attached) and a utility area.
What Does It Cost?
| Built-up area | Basic (₹1,700–2,000) | Standard (₹2,000–2,500) | Premium (₹2,500–3,500) |
|---|---|---|---|
| 1,300 sq ft | ₹22 – 26 lakh | ₹26 – 32.5 lakh | ₹32.5 – 45.5 lakh |
| 1,500 sq ft | ₹25.5 – 30 lakh | ₹30 – 37.5 lakh | ₹37.5 – 52.5 lakh |
| 1,600 sq ft | ₹27 – 32 lakh | ₹32 – 40 lakh | ₹40 – 56 lakh |
These cover the building on built-up area. Add 10–20 percent for approvals, design fees, sump, septic tank, compound wall, borewell and connections, and budget interiors separately.
Single Floor or Duplex?
| Single floor | Duplex | |
|---|---|---|
| Plot needed | Larger | Smaller (half the footprint) |
| Foundation and roof area | Full plan | Half the plan |
| Staircase | None internal | Internal stair adds area and cost |
| Total built-up | Lower | Higher for the same rooms |
| Cost per sq ft | Slightly higher | Slightly lower |
| Daily living | No stairs | Stairs between bedrooms and living |
On Hyderabad's common 150–200 sq yard plots, a 3BHK usually has to go duplex or G+1 to fit, after setbacks.
What Materials Does a 1,500 sq ft 3BHK Need?
| Material | Thumb rule | Approx. quantity |
|---|---|---|
| Cement | 0.4 bags / sq ft | about 600 bags |
| Steel | 3.5 – 4.5 kg / sq ft | 5.3 – 6.8 tonnes |
| Sand | 1.8 cft / sq ft | about 2,700 cft |
| Aggregate | 1.35 cft / sq ft | about 2,000 cft |
At these quantities, a difference of ₹2 a kg on steel is ₹10,000 to ₹14,000, and ₹10 a bag on cement is ₹6,000. Getting suppliers to compete for each stage's order is worth the effort.
Where Do 3BHK Budgets Overrun?
The frame of a 3BHK is engineered and its material quantities are predictable. Overruns usually come from:
- Bathrooms. Three bathrooms with premium sanitaryware, fittings and wall tiles to the ceiling can add several lakh.
- Flooring upgrades across a larger area.
- False ceilings and lighting added room by room.
- Woodwork — wardrobes in every bedroom, kitchen cabinets, TV units.
- Elevation changes after the structure is designed.
Fixing a finishes specification before you sign with a contractor, and pricing interiors separately, keeps these visible.
The Short Version
Budget ₹30–37.5 lakh for a 1,500 sq ft 3BHK at standard finishes in 2026, plus extras. Decide single floor or duplex from your plot after setbacks, buy cement and steel at stage volume, and watch the bathrooms and woodwork — that is where 3BHK budgets drift.
