A duplex is one of the most sought-after types of home or, at the very least, one of the most appealing to many buyers, thanks to the advantages it offers as a place to live.
Below, we explain everything you need to know about what a duplex is and what it can offer, so that if you come across one in a property listing, you will understand the possibilities it offers compared with other properties.
What is a duplex?
A duplex is a type of home arranged over two levels connected by an internal staircase, making it possible to separate day and night areas and optimise the use of space. It may also be associated with a single-family home such as a detached house, or with a multi-family residential property.
In the latter cases, this type of home is quite often located on the top floor and marketed as a “duplex penthouse", which is particularly attractive as it combines the height and views of a penthouse with the distinctive layout of a duplex.
Main features of a duplex
Every duplex is unique, but that does not prevent us from identifying some general features that define what a duplex flat is:
- Two floors: clearly, the split-level layout is the most important feature of a duplex, which will always have an internal staircase and, in some cases, a private lift as well.
- Natural light: a duplex places particular emphasis on natural light and usually has large windows on both floors.
- Spaciousness: the presence of internal stairs encourages architects to design duplexes with a strong sense of space, in order to guarantee maximum comfort for residents.
- Privacy: the division into two floors provides greater opportunities for privacy for occupants who do not wish to remain in the communal areas.
- Outdoor space: in general, every duplex has access to outdoor areas, whether a garden, terraces or balconies.
Advantages and disadvantages of duplexes
Buying a duplex offers many advantages, although it also has certain disadvantages that should be taken into account.
Advantages of duplexes
- Properties with more space than traditional homes.
- Excellent natural light in virtually every room.
- Better views, especially in the case of a penthouse.
- A highly attractive contemporary design, thanks to the internal staircase.
- A greater sense of independence within a residents’ community.
- Greater scope for personalising the internal layout.
- Capital appreciation: they tend to perform better on the resale market.
Disadvantages of duplexes
- A higher price than other housing alternatives.
- Internal staircases, although aesthetically attractive, can be a limitation for people with reduced mobility or families with young children.
Differences between a duplex and a terraced house
A duplex is a home with two floors connected by an internal staircase, which may be located within a building, for example on the third and fourth floors.
A terraced house, by contrast, has direct access from the street, usually includes a garden, garage and several storeys, and shares side walls with adjoining properties.
Likewise, a terraced house does not necessarily have to be a duplex; it may also be arranged on a single floor (simplex).
Frequently asked questions about duplexes
Is a duplex more expensive to maintain than a single-family home?
A duplex has more space than most homes, but if we compare it with a single-family home such as a detached house, its characteristics are fairly similar.
It therefore does require more maintenance than a standard flat because, for example, there are internal stairs to look after, which are not usually found in other properties.
However, compared with a single-family home, it is more similar and may even be easier to maintain, as it does not include features such as a porch, swimming pool and other spaces that those properties may have.
What should I consider when buying a duplex?
If you are thinking about buying a duplex, there are certain points you should bear in mind:
- The investment required is higher than for other properties, so it should be a type of home that genuinely appeals to you.
- Most of these homes are fairly spacious, which is why they are often recommended for families.
- It is ideal if you want to enjoy spectacular views, especially in the case of a duplex penthouse.
- Stairs are very attractive and help keep you active, but they can also be a drawback in certain circumstances.
- If you are looking for a bright home, you will find that this feature is usually very well achieved in any duplex.
