However, what is a duplex house and does it suit your needs? In this article, we will discuss everything that you should know about duplex houses in India, such as the definition, Types, pros, cons, cost of building them, and some valuable recommendations.

What is a Duplex House?

In simple terms a duplex is basically a single-family building consisting of two floors connected by an internal staircase. In the Indian subcontinent, a duplex means a house built on two floors to serve a single family. The structure of such a house is very effective because on the ground floor there is usually a living room and kitchen, and a dining room, whereas upstairs there are bedrooms and toilets.

Misunderstandings About The Duplex House

Is it any 2-storey home? Well, not exactly. The house will be considered a two-story multi-family house, rather than a traditional duplex, if there is a separate external entry and kitchen for a second family in the upper story.

Does It Belong To An Apartment Building? The duplex can be constructed as an independent house or within a multi-story apartment building, which is often referred to as a duplex apartment.

Types of Duplex House

There are several types of duplex houses available depending on the type of layout of the two units, geographical location, and requirements of the buyers.

1. Standard Duplex: This is the most common style of a house in the real estate sector. The bottom section of the house contains all rooms, including the sitting room, kitchen, and dining area. The second level of the house contains all the master bedrooms.

2. Ground Floor Duplex: There are houses called ground-floor duplexes which many people like. These types of houses contain two floors. In some cases, these houses contain a garden or a patio in the backyard.

3. Low Rise Or Penthouse Duplex: These kinds of duplexes are found in the floors of skyscraper apartments. These duplexes have different floors and have views of the city.

4. Side-by-Side Duplex: Side-by-side duplexes are commonly found in international or suburban architectural designs, where two living spaces are placed next to each other on one piece of land with a common wall. In Indian architecture, vertical duplexes continue to be the preferred option.

Duplex House vs Apartment vs Villa

Choosing the most appropriate housing option will depend on the need to find a balance between your monetary needs and practical living requirements. Apartments suit those who do not want to put any effort into community living; villas offer maximum luxury independently, while duplexes are somewhere in the Middle. These are the following comparisons between the three housing options.

Key Features of a Duplex House

Today's duplex houses use vertical space effectively to combine luxury and practicality. Compared to regular apartments, such two-storey architecture not only allows for dividing functional spaces but also increases the presence of daylight and proper ventilation. Utilising high-end construction materials, duplex houses provide bright social places combined with intimate private spaces. The following features will highlight how duplexes are designed nowadays.

1. Internal Staircase

The interior staircase is the heart of the entire structure of the duplex and connects the ground floor and upper floor from the inside of the house. In the modern era, not only does its functionality matter, but it is also used as a key element in the whole design of the house. People nowadays use floating stairs or even glass railings to save space.

2. Separated Living Zones

Naturally, there are two functional areas in a duplex to maintain a balance between having guests over and being comfortable at home. The ground floor becomes the place where you meet your guests, which contains the living room, the kitchen, the dining area and even the bathrooms for guests. The top floor is used as your sanctuary.

3. Double-Height Ceilings

One important characteristic that luxury duplexes have is the presence of double-high ceilings, which are normally found above the living space. By removing some portions of the second floor, the living space. By removing some portions of the second floor, the living space becomes vertically connected to the roof of the building. Such an architectural feature makes small spaces look big and gives the house great ventilation through large windows.

4. Multiple Balconies

A duplex differs from a regular flat because it gives you a chance to experience the outdoors from several levels of the building. Usually, the first level’s balcony comes off the living room or the dining room and serves as an outdoor reception area or mini garden. The second floor’s balconies are linked directly to your bedrooms.

Things To Check Before Buying A Duplex House
