4 BHK (4 bedrooms, 1 hall and 1 kitchen) houses are a common residential typology, especially in urban areas. The demand for such houses is rapidly increasing with a rise in the general economic status in cities, and they are popular among growing families and young professionals alike. However, navigating the 4 BHK house price ranges can be a tricky task. Therefore, Brick & Bolt presents a comprehensive guide to calculating a 4 BHK house construction cost in India. Read on to learn more.
Factors That Affect 4 BHK House Construction Cost
The cost of building a 4 BHK house in India is dependent on several factors such as:
- Site location: Construction is generally more expensive in cities than in rural areas.
- Design complexity: A simple 4 BHK house design will cost less than an intricately designed 4 BHK bungalow.
- Site and soil conditions: Sites with steep slopes and/or weak soil require higher expenditure.
- Carpet area, built-up area and super built-up area and number of floors: The higher the built-up area, the higher the cost. For example, a 4 BHK house plan in 2000 sq ft will cost more than one in 800 sq ft.
Calculating the Area of a 4 BHK House Plan
Generally, building project costs are calculated on the basis of construction cost per square foot, which is multiplied by the total built-up area to obtain overall construction cost. Thus, we must first estimate the built-up area of a typical 4 BHK home design before being able to calculate the construction cost. A 4 BHK villa can be built on any plot size, ranging from 300 sq ft to thousands of sq ft.

As witnessed from the above two floor plans, 4 BHK houses have very wide-ranging built-up areas. Explore more 4 BHK floor plans by Brick & Bolt and discover inspiring 4 BHK house elevation design ideas.
We can consider three different examples for estimating the area of a 4 BHK house in order to calculate its construction cost:
- Single Floor 4 BHK House With Minimal Room Sizes
The room sizes and areas for such a house can be assumed to be:
- Living room (hall): 10’0” x 12’0”= 120 sq ft
- Kitchen: 8’0” x 9’0”= 72 sq ft
- Bedroom 1: 10’0” x 10’0”= 100 sq ft
- Bathroom 1 (common WC): 4’0” x 5’0”= 20 sq ft
- Bedroom 2: 10’0” x 10’0”= 100 sq ft
- Bathroom 2: 4’0” x 7’0”= 28 sq ft
- Bedroom 3: 10’0” x 10’0”= 100 sq ft
- Bedroom 4 (master bedroom): 10’0” x 12’0”= 120 sq ft
- Bathroom 3: 5’0” x 8’0”= 40 sq ft
Carpet area= 700 sq ft
- Area of walls in plan (assuming a minimum of 15% of the carpet area)= 105 sq ft
Total built-up area= 805 sq ft
- Duplex 4 BHK House With Comfortable Room Sizes and 1 Car Parking
The room sizes and areas for such a house can be assumed to be:
- Living room (hall): 14’0” x 12’0”= 168 sq ft
- Kitchen: 12’0” x 9’0”= 108 sq ft
- Bedroom 1: 10’0” x 12’0”= 120 sq ft
- Bathroom 1 (common WC): 4’0” x 5’0”= 20 sq ft
- Bedroom 2: 12’0” x 12’0”= 144 sq ft
- Bathroom 2: 4’0” x 8’0”= 32 sq ft
- Bedroom 3: 12’0” x 12’0”= 144 sq ft
- Bedroom 4 (master bedroom): 14’0” x 12’0”= 168 sq ft
- Bathroom 3: 5’0” x 8’0”= 40 sq ft
- Staircases, landings and other circulation spaces= 200 sq ft
Carpet area= 1144 sq ft
Area of walls in plan (assuming a minimum of 15% of the carpet area)= 171 sq ft
Built-up area= 1144+171 sq ft= 1315 sq ft
- Car parking: 150 sq ft
- Utility and 2 balconies: 100 sq ft
Area of semi-enclosed spaces= 250 sq ft
- Duplex 4 BHK House With Spacious Room Sizes and 2 Car Parking
The room sizes and areas for such a house can be assumed to be:
- Living room (hall): 14’0” x 16’0”= 224 sq ft
- Kitchen: 14’0” x 10’0”= 140 sq ft
- Bedroom 1: 12’0” x 12’0”= 144 sq ft
- Bathroom 1 (common WC): 4’0” x 6’0”= 24 sq ft
- Bedroom 2: 14’0” x 12’0”= 168 sq ft
- Bathroom 2: 5’0” x 9’0”= 45 sq ft
- Bedroom 3: 14’0” x 12’0”= 168 sq ft
- Bathroom 3: 5’0” x 9’0”= 45 sq ft
- Bedroom 4 (master bedroom): 14’0” x 14’0”= 196 sq ft
- Bathroom 4: 6’0” x 9’0”= 54 sq ft
- Staircases, landings and other circulation spaces= 400 sq ft
Carpet area= 1608 sq ft
Area of walls in plan (assuming a minimum of 15% of the carpet area)= 241 sq ft

- 2 Car parking: 300 sq ft
- Utility and 3 balconies: 200 sq ft
Area of semi-enclosed spaces= 500 sq ft
