Although they have become quite common in Indian real estate, a lot of confusion still persists, with regard to duplex house meaning. As they are often confused with two-storey homes, let us find out what a duplex is and how it is different from two-storey homes.
What is a duplex house?
A duplex house is a residential building constructed on two floors. It has a single dining room and a single kitchen. It has a common central wall and consists of two living units, either side-by-side or on two floors, with separate entries. While there are two floors, it is sold together and owned by an individual. It may have separate entry points for both floors.
In India, duplexes generally have a kitchen, hall and bedrooms on the lower floor while the upper floor houses the master bedroom. A duplex always has two floors and never three or four floors, in which case it would be called a multiplex.

In western countries, duplex homes may even house two families, where each floor is a separate dwelling altogether. Duplexes can provide healthy rental returns, because the owner family can always rent out one section of their property to tenants. In such cases, the entrance will be separate and a common wall will divide the large house into two.


Difference between two-storey house and duplex
A duplex house is always a two-storeyed structure but all two-storeyed buildings may not be categorised as duplexes. In duplexes, the floors are connected through a staircase, while two-storeyed properties may be independent of each other and may or may not be connected.

Difference between duplex and villa
A villa may or may not be a two-storeyed property and is usually larger than a duplex house. Both are used for residential purposes but a villa is considered as a plush purchase, when compared to a duplex. A villa is generally the first choice for those who want total privacy. In fact, the villa concept dates back to the Roman era, when the rich and the famous moved to the countryside during the summers. Today, villas may be independently owned homes in a plot of land but yet are within a gated community. Villas also offer amenities such as a clubhouse, gym, pool, etc., unlike a duplex.

Difference between duplex and penthouse
Unlike a duplex that is a two-storeyed property, a penthouse is always located in the top floor of a multi-storey building or apartment. These units are expensive, as they offer a good view and are generally the only unit on that particular floor design. All the units that were supposed to be on this floor, are consolidated into one.


Difference between duplex and independent house
The term ‘independent home’ is used interchangeably to refer to villas, duplexes and the like. An independent house may have as many floors as desired but a duplex essentially has two floors.
What is the cost of building a duplex house in India?
Depending on the exact location and city, a duplex construction may cost anywhere above Rs 1,500 per sq ft if you go in for basic finishing materials.
