Duplex House in Nigeria: Definition

In Nigeria, a duplex house refers to a residential building comprising two floors. Unlike the global definition of a duplex as a structure housing two separate families, Nigerian duplexes are typically occupied by a single family. The ground floor commonly hosts the kitchen and main living room, while the upper floor accommodates private rooms, including the master bedroom, connected by a staircase.

Pros and Cons of Building a Duplex in Nigeria

Pros:

1. More space within: Duplexes offer ample interior space, allowing for spacious living rooms, kitchens, and large rooms.
2. Larger compound: The vertical structure frees up surrounding space, reducing roofing costs and providing a more expansive compound.
3. Class: Duplexes are often associated with prestige, making them a popular choice among high-profile individuals in Nigeria.
4. Good view: Balconies on the top floor provide an excellent vantage point for observing the surroundings.
5. Security: The vertical layout enhances security by making it challenging for intruders to access upper-floor windows.

Cons:

1. More expensive: Duplex construction is costlier due to additional elements like decking, pillars, beams, and staircases, requiring substantial concrete and steel reinforcements.
2. Inconvenience: Frequent movement between the top and ground floors may pose challenges in daily activities.

Conclusion
