Duplex vs. Apartment / Flat
Housing Structure
Apartment/Flat: In apartments or flats, everything is on one level. Your kitchen, bedroom, and bathroom are all accessible without stairs. In the US, “apartment” is the standard term, while in the UK, people always say “flat.”
Duplex: In the urban context, a duplex is simply an apartment with a second story. The primary advantage here is the separation of living zones (e.g., bedrooms upstairs, social areas downstairs).
Ownership
- Duplex: usually owned by one person. The owner can live in one unit and rent out the other, or rent out both units. Many new landlords like duplexes because the rent from one unit can help pay the mortgage.
Apartment: Most apartment buildings are owned by one landlord or one company. All units in the building are usually rented to tenants.
Duplex vs. Penthouse
Penthouse: This strictly refers to the top floor unit of a building. Penthouses are often luxurious and can be duplexes (two floors), but they can also be single-story.
Duplex: A duplex can be on the top floor (making it a duplex penthouse), but it can also be on the ground floor and basement. “Duplex” refers to the layout, while “Penthouse” refers to the location.
Duplex vs Maisonette
Maisonette: Derived from the French for “little house,” a maisonette is a two-floor flat that usually has its own front door opening directly to the street. You do not pass through a communal lobby or corridor.
Duplex (UK): A two-floor flat where you typically enter through a communal building lobby or shared hallway before reaching your unit’s door.
Tips: If you want zero interaction with neighbors in a hallway, choose a maisonette. If you want the security of a concierge or building lobby, choose a duplex.
Are Duplex Apartments Popular in the UK or the US?
Duplexes are in demand and popular in both the UK and the US. Most of the younger generation in the UK do not have the habit of saving money, so it may be difficult for them to buy a house. Besides, they prefer the low-cost and flexible renting life. There is still a high demand for long-term rental apartments, including duplex houses.
In the US, more than 50% of residential building lessors are apartment lessors, and they represent over 90% of operating income. This shows that apartment rental is the dominant force in the American residential rental market. In some large cities, such as New York, affordable duplexes may be more popular due to limited land resources and high population density.
Pros of Living in a Duplex Apartment
- Affordability:
Duplexes are generally more affordable than single-family apartments, making them a great option for budget-conscious families or individuals, especially in large cities like New York and Boston. This is particularly beneficial for recent graduates who may struggle to afford traditional student apartments or standalone houses. Renting a duplex offers a practical way to save money.
- Utilization:
Duplex apartments are designed to maximize land utilization. It can provide two relatively separate living environments by sharing a common wall. Besides, each unit in a duplex apartment offers more amenities, such as a kitchen, bathroom and bedroom, ensuring personal privacy and independence for occupants.
- Flexibility:
There are several ways to deal with duplex apartments. Occupants can adapt the use of the units to suit their needs, such as using one of the units as a home office or storage. Additionally, they can rent out one of the apartments, as there is always someone searching for “duplex apartments near me.” This indicates a strong demand for this type of housing.
- Low maintenance costs:
Maintenance costs can be lower in a Duplex compared to a single-family home because both units share some common facilities and systems. This helps reduce the occupants’ daily expenses.
- Convenience:
Duplexes are typically located near major transportation, shopping centers, schools, and parks. It’s very convenient to go out. For those working or studying in large cities, living in a duplex can save commuting time and improve overall well-being.
Cons of Living in a Duplex Apartment
- Noise:
One of the biggest problems of living in a duplex is noise and neighbors. The daily habits of neighbors can have a significant impact on your living experience. Because the two units of duplex apartments share a common wall, residents may be disturbed by noise from neighbors.
The “Pivot!” Problem (Stairs)
If you have ever seen that episode of Friends, you know the struggle. Moving furniture up a narrow, winding internal staircase in a duplex apartment can be a nightmare. Getting a queen-size mattress or a heavy desk to the second floor often requires professional help or disassemblable furniture. Furthermore, if you or a roommate has mobility issues or even a temporary injury (like a sprained ankle from sports), the stairs become a major daily obstacle.
- Utilities and Climate Control
Heat rises. In a duplex apartment, the upper floor (bedrooms) is often significantly hotter than the lower floor. In summer, you might need extra AC power to keep the bedrooms cool. In winter, all the heat from the living room rises to the bedroom, leaving your downstairs hangout area chilly. This can lead to higher utility bills compared to a single-level flat, where temperature is easier to regulate.
- Limited outdoor space:
Duplex homes typically have a smaller footprint, which may limit residents’ access to larger outdoor spaces or gardens. This can be a disadvantage for families who like outdoor activities.
- Privacy:
Even though living in a high-rise duplex apartment, personal privacy is still a concern. Besides, sharing a common wall with your neighbors means you may be unable to design or remodel your interior precisely as you would like. Therefore, residents need to take extra steps to protect their privacy, such as installing soundproofing materials or curtains.
- Maintenance responsibilities:
The two units at Duplex share some common facilities and systems, so defining the maintenance responsibilities is more complicated. Residents need to negotiate and share maintenance costs and responsibilities with their neighbors, which may lead to some disputes.
What to Consider When Renting a Duplex Apartment
1. Location: Check out the amenities near a duplex flat, such as grocery stores and public transportation. A suitable location can bring great convenience to your life.
2. Maintenance Responsibilities: Different duplexes have various age ranges. Generally, the older the buildings are, the more maintenance they require. Clarify your maintenance responsibility with the owner or your neighbor. Make sure that any necessary renovations or fixes are addressed before you sign the lease.
3. Housing structure: The housing structure of each duplex may differ. For example, the bedrooms in some duplexes are on the upper level, which is more private for renters. If you have more stuff, you can choose a housing duplex with more space for storage.
4. WiFi Connectivity: This is a modern problem specific to duplexes. A standard router placed downstairs often cannot push a strong signal through the concrete or timber ceiling to the rooms upstairs. Check if the landlord provides internet. If you are setting it up yourself, be prepared to buy a WiFi Extender or a Mesh System to ensure you can submit assignments from your bed upstairs.
5. Budget: When negotiating rent and deposits with your landlord, ensure the rent fits your budget and that the deposit terms are clear. Clarify which utilities are included in the rent and which you’ll pay separately to help plan your budget effectively.
6. Neighbors: Living in a nice and safe community is also important to people’s lives. Try as much as possible to find a friendly neighbor. You can also visit the duplex apartment in advance and get to know the real community directly.
7. Pet Policy: If you want to have a pet, you can consult in advance to ensure pets are allowed in the duplex for sale or rent. Figure out if there are any associated fees or restrictions, and find a suitable duplex apartment.
