30x40 to 39x49 Ft House Plans: 1BHK to 6BHK Designs With Vastu
Unlocking the Full Potential of a 30x40 Site
The "Gold Standard" of Indian Real Estate If you own a plot sized 30x40 ft (1200 sq. ft.) up to 39x49 ft, you own the most versatile piece of land in the market. It is often called the "King of Plots" because it is perfectly sized. You don't need a massive estate to build a palace; you just need smart planning. At Apzok, we have pushed the boundaries of what a 30x40 site can do. From a modest 1BHK rental unit to a massive 6BHK joint-family Triplex, our collection covers every need, strictly following the ancient laws of Vastu Shastra. And yes, every single plan comes with a 100% Free 3D Walkthrough so you can see it to believe it.
From 1BHK to 6BHK: The Magic of Vertical Building Many people think a 30x40 plot is only good for a small 2-bedroom house. That is a myth. By utilizing vertical space (G+1 or G+2 floors), we transform 1200 sq. ft. into a mansion.
-
The Rental Earner (1BHK & 2BHK): We often design the ground floor with parking and a compact 1BHK unit. This is perfect for tenants or an elderly couple.
-
The Family Home (3BHK & 4BHK): A standard Duplex (G+1) on a 30x40 site easily accommodates a spacious 4BHK. You get a grand living hall and kitchen below, and private bedrooms above.
-
The Joint Family Mansion (5BHK & 6BHK): Yes, it is possible! By building a Triplex (G+2), we can fit 6 spacious bedrooms. We place the grandparents' room on the ground floor Nairuthi corner, creating a multi-generational home that feels massive inside.
Vastu Shastra: Balancing the Energies In a compact 30x40 rectangle, placement is everything. We use specific Vastu zones to ensure prosperity:
-
Nairuthi (South-West): The Master Bedroom is strictly placed here. This zone provides stability and commands the house. We never place a toilet or borewell here.
-
Agni Moola (South-East): The Kitchen acts as the "fire engine" of the home. Placing it here ensures health for the family.
-
Ishanya (North-East): This is the "God Corner." We keep this zone light and open, often designing a beautiful Puja room or the main water sump here.
-
Brahmasthan (Center): In our 30x40 plans, we avoid putting walls in the exact center. We create a "Hall-Dining" flow to keep the Brahmasthan breathing.
Why the 3D Walkthrough is Essential When you pack a 6BHK into a 30x40 footprint, the design becomes complex. A simple blueprint can look cluttered. Our Free 3D Walkthrough allows you to virtually "walk" up the stairs, check the headroom, see the balcony views, and understand how the house flows from the Agni corner to the Nairuthi corner. It removes all the guesswork.

Frequently Asked Questions about 30x40 Plans
Yes, but not on a single floor! To get 6 bedrooms on a 30x40 plot, you need to build a Triplex (Ground + 2 Floors). We typically design 1 bedroom on the Ground floor (for elders), 3 bedrooms on the 1st floor, and 2 bedrooms on the 2nd floor. This gives you a massive joint family home on a standard plot.
Without a doubt, it is the Nairuthi (South-West) corner. In all our layouts, the head of the family sleeps here to ensure stability and leadership. If you are building a Duplex, the Master Bedroom on the upper floor should also be in the South-West, directly above the lower one.
Absolutely. This is a very popular "Rental + Owner" design. We use the front 15 feet for a large Car Parking porch and a staircase. Behind that, we fit a comfortable 1BHK unit (approx 600 sq. ft.) which can be rented out or used as a guest suite.
The Puja room belongs in the Ishanya (North-East) corner. Since 30x40 is a compact size, we often integrate a 4'x5' Puja niche in the Hall or Dining area facing East, ensuring it captures the morning sunlight.
