Penthouse vs Duplex: What advantages do duplex apartments or houses offer over a penthouse, and vice versa?

Whether it's a growing income, a larger family, or the desire for a home that reflects your success, deciding between a duplex and a penthouse is more than just a choice about space or location. It’s about how each type of residence aligns with your lifestyle, needs, and aspirations.

A penthouse embodies exclusivity and grandeur. It offers breathtaking views, expansive terraces, and an open-plan design ideal for a social, modern lifestyle. Situated at the very top of a building, a penthouse is bathed in natural light and exudes an unmistakable sense of luxury.

On the other hand, a duplex focuses on functionality and privacy. Imagine a clear division between living and sleeping areas, connected by an elegant internal staircase. This layout is ideal for families or those who appreciate a well-organized, defined space.

At Bellemonde, you’ll experience the best of both worlds. Our luxury duplexes blend the brightness and elegance of a penthouse with the privacy and practicality of a duplex. Located in low-rise buildings surrounded by nature, away from urban noise, they feature large windows, spacious terraces, and open-plan living areas. With penthouse-inspired designs, these duplexes provide a serene and sophisticated living experience—that’s the Bellemonde promise.

In this article, we’ll explore how these homes address essential questions, analyze the advantages and trade-offs of each option, and demonstrate how Bellemonde elevates duplex living into a premium experience.

What is a Penthouse?

A penthouse is typically a top-floor apartment offering generous interior space, large terraces, and stunning panoramic views that set it apart from other units in the building. Positioned on the highest floor, a penthouse provides increased privacy and is the perfect choice for those seeking luxury, premium design, and a distinctive atmosphere.

While the layout of a penthouse depends on the available space and the building’s design, it is defined by high-end finishes and a sleek, modern style. Some penthouses are single-level for maximum fluidity, while others, less commonly, feature two levels connected by a stylish internal staircase.

A hallmark of penthouses is their expansive terraces. These outdoor spaces extend the living area, offering the perfect spot to admire the view, unwind, or host social gatherings.

Modern penthouses are highly customizable, whether through an open-plan layout for maximum light and social connectivity or through designs that clearly separate day and night areas for greater privacy.

Originally, the term “penthouse” referred to a house-like structure built atop a building, often recessed to create a large outdoor area with stunning views. Today, the definition has broadened to attract buyers and renters. For instance, some ground-floor units are marketed as penthouses if they feature exclusive amenities, premium finishes, and standout design.

Modern penthouses may include oversized windows, captivating views, expansive floor plans, private entrances, enhanced security, upgraded appliances, and large terraces.

What is a duplex?

A duplex can refer to an apartment spanning two internal levels or a duplex house consisting of two independent living units. Both types of duplexes share the benefit of functional space separation, though they cater to different lifestyles.

Designed to clearly delineate between day and night areas, a duplex strikes a balance between functionality and privacy, making it a perfect fit for modern living.

The dual-level layout significantly influences how the space is used, allowing multiple activities to occur simultaneously without interference. For example, one family member can cook or work in the living area while another rests or studies upstairs in a quiet, private environment. This setup is particularly well-suited to families with children or couples who value flexibility.

Typically, the lower level is dedicated to daytime activities, featuring the living room, an often open kitchen that encourages social interaction, and sometimes an office or playroom. These spaces are designed to facilitate daily family life and interaction.

The upper level is reserved for nighttime use, hosting bedrooms and main bathrooms. This layout fosters tranquility and privacy, even when the downstairs area is bustling with activity.

Duplexes offer more layout options compared to single-level apartments. The vertical design creates a sense of open space, while the internal staircase serves as both a functional and architectural highlight, adding elegance and dynamism.

Another notable advantage is the flexibility of the living spaces. The day area can be tailored into a modern office, a children’s playroom, or an expanded social area, while the upper floor remains a sanctuary for rest and relaxation. This smart compartmentalization makes duplexes an excellent choice for those seeking a well-organized home that meets all daily needs without compromise.

How Does Budget Influence the Choice?

Un penthouse is undoubtedly the more expensive option due to its spacious layout, luxurious finishes, and expansive terraces that offer stunning panoramic views. It’s the perfect choice for those with a generous budget seeking an exclusive residence and a refined lifestyle.

What is Your Lifestyle?

A penthouse caters to those seeking a luxurious and exclusive lifestyle. With its modern design, premium finishes, and impressive open-plan layout, it’s perfect for individuals who lead an active social life. If you enjoy hosting parties or relaxing evenings with friends in a sophisticated setting, a penthouse is a perfect match.

A duplex is better suited for families or couples who value an organized environment with a clear distinction between living and sleeping areas. It’s ideal for those who want the comfort of a house with access to green spaces, combined with the conveniences of urban living. A duplex offers more space and privacy, making it a versatile option for a balanced lifestyle.

What Are Your Individual Needs and Preferences?

If you’re looking for an exclusive space with large terraces, stunning views, and luxurious features, a penthouse might be the perfect choice. It appeals to those who value premium comfort and privacy while enjoying an active social life.

For families or those who need more living space, efficient layouts, and plenty of storage, duplex houses or apartments are ideal. They are designed for those who appreciate the separation between day and night areas and often include the bonus of a private yard or terrace.

Did you know?

Bellemonde is a residential community designed to offer its future residents a greener lifestyle, closer to nature. With 33% of its surface dedicated to green spaces, the development includes maintained common areas that relieve residents of gardening responsibilities, alongside private gardens and rooftop terraces for homes in the complex.

Located in Pipera, away from the bustling center of Bucharest, Bellemonde benefits from reduced pollution due to its proximity to Băneasa Forest. Here, you’ll enjoy cleaner air, a quieter life, and greater privacy, with just 164 residences spread across 4 hectares of land.

What Kind of Outdoor Space Do You Want?

If you prefer an elegant setting that provides a stunning backdrop for social events or moments of relaxation, the terraces of a penthouse are an excellent option. They’re perfect for those who value a sophisticated urban lifestyle. However, keep in mind the increased exposure to nature’s elements, such as strong winds or intense sunlight.

On the other hand, if your dream is to enjoy a personal oasis at ground level, duplex homes are a better fit. They offer added functionality for families or individuals who love gardening and connecting with nature. That said, a private garden does come with maintenance responsibilities.

Your choice ultimately depends on what you value more: the impressive aesthetics and low maintenance of a penthouse, or the tangible connection to nature and versatility provided by a duplex. Weighing these advantages and trade-offs will help you find the perfect home to meet your needs.

Did you know?

At Bellemonde, you can enjoy the best of both worlds. Duplexes come with private gardens that let you connect directly with nature, while the rooftop terraces of penthouse-inspired duplex apartments provide a sophisticated space for relaxation or elegant events, far from the city’s chaos.

Additionally, the Social Hub at Bellemonde adds a unique social dimension to everyday life. This communal space is perfect for hosting events, meeting friends, or even throwing small parties without worrying about logistics or limited space. Bellemonde seamlessly combines the sophistication of a penthouse with the functionality and nature-focused living of a duplex, offering you a fully adaptable and complete lifestyle.

How Important is Privacy in Your Living Space?

Do you value complete separation from neighbors, such as the exclusive access and top-floor positioning a penthouse offers? Or do you prefer the practical functionality and clear division of spaces that a duplex provides?

A penthouse offers privacy through its placement on the top floor, often with private elevators and restricted access. However, such ultra-exclusive features are less common in Romania. The open-space layouts typical of penthouses are ideal for modern, social lifestyles, combining elegant design with seamless transitions between living and sleeping areas. While panoramic views are a major advantage, urban noise can still be a challenge, even at higher altitudes.

In contrast, a duplex provides a clear separation between the day and night areas, thanks to its two-level design. At Bellemonde, this configuration offers functional privacy, ensuring that activities in the living spaces—such as cooking, working, or entertaining—don’t interfere with the quiet of upstairs bedrooms. Additionally, Bellemonde’s duplex homes feature a unique wall structure that is shared yet not directly attached to the neighboring unit. This rare design significantly reduces noise and enhances comfort.

What About Soundproofing?

Soundproofing varies depending on the type of home and its location. Penthouses, situated on the top floor, are naturally isolated from noise within the building but may be exposed to external sounds like wind or air traffic.

How Does Socializing Influence Your Choice?

A penthouse is ideal for those who frequently host events. Its spacious layouts and large terraces provide a sophisticated setting for entertaining guests.

On the other hand, duplexes, particularly those with private gardens or terraces, are better suited for families or those who value community interaction. At Bellemonde, the integrated Social Hub fosters connections among residents, offering a modern space for hosting events, meeting friends, or enjoying community activities. This creates a sense of belonging while maintaining a private living environment.

How Energy Efficient Are They?

Both penthouses and duplexes are designed with modern energy efficiency in mind. Penthouses often include advanced climate control systems and large, thermally insulated windows that maximize natural light. However, the large windows can lead to higher cooling costs during summer.

Duplexes, especially those in suburban areas, frequently feature highly efficient heating systems and optimized insulation. Many include solar panel infrastructure, further reducing energy consumption. At Bellemonde, duplexes are equipped with ventilated facades and eco-friendly solutions to enhance energy efficiency.

What Are the Associated Costs for Shared Spaces?

Penthouses typically have higher associated costs due to premium amenities, such as private elevators, rooftop terraces, or exclusive common areas. Duplexes, particularly those in suburban developments, often have lower costs for shared spaces but may include responsibilities for maintaining private gardens or green areas. At Bellemonde, residents benefit from a balanced approach: access to a Social Hub and shared green spaces while keeping costs manageable.

How Do Resale Value and Market Trends Compare?

Penthouses maintain their value in luxury urban markets due to their exclusivity and consistent demand from high-end buyers. However, market volatility can impact their appeal if urban migration trends shift.

Duplexes are increasingly popular, particularly in suburban areas, thanks to their versatility. They attract families and buyers looking for multifunctional homes, offering potential for multi-generational living or partial rental opportunities, which boosts long-term demand.
