Frequently Asked Questions about 20x20 Plans
Yes, a 20x20 plot (400 sq. ft.) is ideal for a "Nano Duplex." You can have a living room and kitchen on the ground floor and a large master bedroom with an attached bath on the first floor. This gives the feel of a larger home on a tiny footprint.
While all directions can be Vastu compliant, North and East facing plots are easiest to design for in this size range because they allow for the placement of the main door in the positive zones (Ishanya/Kubera) without wasting space on long corridors.
For a standard quality finish, the construction cost in India is approximately ₹1,600 to ₹2,000 per sq. ft. For a 25x25 (625 sq. ft.) single floor, the cost would range between ₹10 Lakhs to ₹12.5 Lakhs.
For plots narrower than 25 feet (like 20x25), car parking is difficult without sacrificing the living room. However, for sizes like 25x25 or 20x29, a small hatchback parking space (8'x12') can be integrated into the ground floor layout.
