Section 2: Duplex House in Nigeria – Definition and Layout

In Nigeria, a duplex house is commonly referred to as a “detached house,” comprising two floors. The ground floor typically houses the kitchen, dining room, and main living room, while the upper floor accommodates the master bedroom and other private rooms, connected by a staircase. Unlike Western countries where duplexes may house two separate families, Nigerian duplexes are usually inhabited by a single family.

Section 3: Pros and Cons of Building a Duplex in Nigeria

Duplex House 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 of a duplex frees up surrounding space, reducing the cost of roofing and providing a larger compound compared to bungalows.
3. Class and Aesthetics: Duplexes are often associated with prestige and class, making them a popular choice among high-profile individuals in Nigeria.
4. Good View: Balconies in duplexes provide a clear view of the surroundings, both within and outside the property.
5. Enhanced Security: Duplexes can be more secure than bungalows as upper-floor windows are less accessible to burglars, offering added security to the residents.

Duplex House Cons

1. Higher Cost: Building a duplex is more expensive than a bungalow due to additional structural elements like decking, pillars, beams, and staircases.
2. Inconvenience: Multiple floor levels can be inconvenient for daily activities, requiring residents to move between the top and ground floors regularly.
