Why “How Much Does It Cost?” Is a Hard Question to Answer
Before looking into cost, lets understand why this question is hard to answer:
- Everyone’s requirements are different. Like one needs a big house and one needs a compact house.
- More brands available to choose with materials. Like cement is available in brands like Ultratech, Ramco, Dalmia, Chettinadu and more
- Material prices and quality vary for the same products. Like you can select a bath shower with 500 rupees or even 10,000 rupees.
- Labour charges vary across cities and villages.
- There is a difference between standard and luxury finishes.
- Hidden costs like water tank, EB connection, sump, and approvals.
So instead of giving you a number right away, lets take it step by step.
🧭 Step 1: Know Your Real Requirements
If you are planning your dream home, don’t start by copying your neighbors house or a YouTube plan.
Instead, ask yourself:
🏡 What do you really need in your 3BHK?
- How many people will live there?
- Do you need a pooja room?
- Do you want attached bathrooms or common ones?
- Is parking space important to you?
- Do you want a future ready first floor?
- Should there be space for utility, washing machine, storage?
These answers directly connect to the built-up area, and that decides your budget.
👉 For this example, lets assume your home is 1350 sq ft of built-up area.
This size usually fits:
- 3 bedrooms (3 attached bathrooms)
- 1 hall
- 1 kitchen + utility area
- 1 common bathroom
- 1 sit-out or balcony
- Staircase space (internal or external)
This is perfect for a family looking 3BHK house.
💸 Step 2: Set the Right Construction Rate (Not Just Cheap or Costly)
Now comes the most important part: cost per sq ft.
Lets assume you are planning to build a strong, good quality home and not luxury, not too basic.
That means:
- High-quality bricks or solid blocks
- Strong RCC structure
- Proper waterproofing
- Branded electricals (like Finolex or Anchor)
- Branded plumbing (like Ashirvad or Supreme)
- Good tiles and paint (Kajaria, Asian Paints, etc.)
✅ In Trichy, Tamil Nadu (2025), the cost for this standard quality is around:
👉 ₹2,300 per sq ft (all inclusive of labour + material)
🧮 Step 3: Lets Calculate 3BHK House Construction Cost for 1350 Sq Ft Home
Here is the simple formula:
Construction Cost = Built-up Area × Rate per Sq Ft
Build up area is 1350 square feet and Cost per square feet is ₹ 2300.
So, construction cost is
1350 sq ft × ₹2,300 = ₹31,05,000
✅ House Construction Cost = ₹31.05 Lakhs
This is only the construction cost of your house. But for budgeting you need to check what is included in this house construction cost and whats not included. You can also calculate the total 3bhk house construction cost using the House Construction Budget Calculator.
🔍 Step 4: What’s Included in ₹31.05 Lakhs?
As we are considering a standard package. This price typically includes:
| Work Type | Included? | Notes |
| Earthwork & Foundation | ✅ | Excavation, PCC, Footing, Backfilling |
| RCC Structure (Slab, Beam) | ✅ | Good quality concrete mix |
| Brick/Block Masonry | ✅ | External and internal walls |

| Painting (interior + exterior) | ✅ | Asian Paints, two coats |
| Doors, Windows | ✅ | Flush doors + UPVC/Aluminum windows |

❌ What’s NOT Included?
These are important costs people usually forget:
| Item | Estimated Cost |
| Compound wall | ₹1 – ₹3.5 Lakhs |
| Borewell or Water Source | ₹80,000 – ₹1.2 Lakhs |
| Sump & Overhead Tank | ₹1 Lakh – ₹2 Lakh |
| EB Connection | ₹15,000 – ₹30,000 |

| Architect or Engineer Fees | ₹30,000 – ₹1 Lakh |
| Modular Kitchen & Wardrobes | ₹1.5 – ₹3 Lakhs |

| Furniture & Interiors | Optional |
💡 So even if your base construction is ₹31 Lakhs, you should keep at least ₹35–₹38 Lakhs in hand for a complete, livable house.
