Quick Answer:
What is the 30x50 house construction cost in Bangalore? A 30x50 plot measures 1,500 sq.ft. According to BBMP guidelines, the permissible built-up area per floor is roughly 1,100 sq.ft. For a standard Ground + 1 (G+1) house (2,200 sq.ft total built-up area), the civil construction cost will range from ₹41 Lakhs to ₹46 Lakhs (at ₹1,900 to ₹2,100 per sq.ft). A Ground + 2 (G+2) house (3,300 sq.ft) will cost approximately ₹62 Lakhs to ₹69 Lakhs. This covers turnkey construction but excludes interiors, compound walls, and statutory approvals.
A 30x50 site (1,500 square feet) is considered one of the best plot sizes in Bangalore. Unlike a standard 30x40 site, a 30x50 gives you an extra 10 feet of depth. That extra space means you can have larger bedrooms, a bigger car park, and proper ventilation on all sides.
However, that extra space also means a higher overall house construction cost in Bangalore. If you are planning to build your dream home on a 30x50 plot this year, this guide will provide a highly accurate, floor-by-floor budget breakdown.

1. Calculating Built-Up Area for a 30x50 Plot
The total plot area is 30 ft x 50 ft = 1,500 sq.ft.
However, BBMP byelaws mandate that you leave setbacks (empty space) around the house for ventilation and fire safety. Typically, you must leave:
- 3 to 4 feet on the sides and rear
- 5 to 6 feet in the front for parking and landscaping
After leaving these setbacks, the ground coverage you can actually build on is around 1,100 sq.ft per floor.
Your final budget depends entirely on how many floors you build. We will calculate the costs below using our premium turnkey construction package rate of ₹2,100/sq.ft.
2. Cost for a G+1 (Duplex) House
This is the most popular configuration for homeowners who want a spacious, private residence. The entire G+1 structure is usually designed as a luxurious 3BHK or 4BHK duplex.
- Ground Floor Area: ~1,100 sq.ft (Living, Kitchen, Dining, 1 Guest Bedroom, Car Park)
- First Floor Area: ~1,100 sq.ft (Master Bedroom, Kids Bedroom, Family Lounge, Balcony)
- Total Built-Up Area: ~2,200 sq.ft
3. Cost for a G+2 (Rental + Duplex) House
To generate passive income while still living in a large home, many Bangaloreans build a G+2 structure. The ground floor is designed as a 2BHK rental unit (or two 1BHKs) plus parking, while the owner occupies a 3BHK duplex on the 1st and 2nd floors.
- Ground Floor Area: ~1,100 sq.ft
- First Floor Area: ~1,100 sq.ft
- Second Floor Area: ~1,100 sq.ft
- Total Built-Up Area: ~3,300 sq.ft
4. Cost for a G+3 (Multi-Unit Rental) House
For pure investment purposes, a G+3 layout maximizes rental yield. The ground floor is primarily parking with a small 1BHK or security room. The upper three floors contain 2BHK units.
- Total Built-Up Area: ~4,400 sq.ft (1,100 sq.ft x 4 floors)
Note: If you plan to build G+3 or above, you may need a commercial lift, which costs an additional ₹5 to ₹8 Lakhs. Furthermore, foundation costs will increase as the structure must support more weight.
