A duplex house is a two-story residential unit connected by an internal staircase, built on a single plot. Unlike independent floors that have separate entrances, a duplex functions as one unified home spread across two levels — typically with living areas and kitchen on the ground floor, and bedrooms on the upper floor.

Our duplex designs account for Delhi's building bylaws, FAR regulations, and seismic zone IV requirements.

Frequently Asked Questions About Duplex House Construction in Delhi

What is a duplex house and how is it different from a builder floor?
A duplex house is a single residential unit spread across two floors connected by an internal staircase, functioning as one home. A builder floor is a single floor that forms a complete independent unit with its own entrance — multiple builder floors can exist on the same plot as separate units.
How much does duplex house construction cost in Delhi?
Duplex construction cost in Delhi ranges from ₹2,200 per sqft for standard specifications to ₹4,500 per sqft for luxury builds. A 2,400 sqft duplex costs approximately ₹53 lakhs to ₹1.08 crore depending on material quality and finishing grade.
What is the minimum plot size for a duplex house in Delhi?
A duplex house in Delhi requires a minimum plot size of 100 sq yards (900 sqft) to meet setback requirements and provide adequate built-up area. However, 150 sq yards or above is recommended for a comfortable 3 BHK duplex layout.
Can I build a duplex with a double-height living room?
Yes, Nirman Ved designs duplex homes with double-height living rooms of up to 18 feet. This requires careful structural planning for the first-floor slab opening and additional steel reinforcement, which adds approximately ₹150–200 per sqft to the affected area.
How long does duplex construction take in Delhi?
Duplex house construction in Delhi takes 18–26 weeks depending on size and specifications. The internal staircase and double-height areas require additional structural work compared to standard single-floor construction.
Does a duplex house require separate MCD approval?
A duplex house requires standard MCD building approval like any residential construction in Delhi. Since both floors are part of a single unit, you need one set of approved plans. Nirman Ved handles all MCD/NDMC approvals as part of the construction process.
