Duplex Apartment Interior Design: A Case Study of Petit Gervais
This article explores the innovative Duplex Apartment Interior Design of Petit Gervais, showcasing unique material use and spatial optimization.
When considering Duplex Apartment Interior Design, the Petit Gervais Duplex by AJAR stands out as a prime example of innovative use and optimization of space within the confines of a 50 m² Parisian apartment. This case study serves as a blueprint for transforming compact living spaces into modern, functional homes.

Ground Floor - A Foundation in Concrete and Brick
The Petit Gervais project showcases an exemplary Duplex Apartment Interior Design on the ground floor, utilizing waxed concrete to anchor the living spaces. This material choice creates a solid base that defines the apartment's activity area, lending an almost sculptural quality to the staircase – a central element in the duplex's layout.

The Kitchen: An Extension of Space
Adjacent to the living area, the kitchen embodies the same waxed concrete tones, appearing as a natural extension of the flooring. This seamless design choice enhances the cohesion between the apartment's different areas, essential in duplex interior design. The incorporation of brick-colored elements alongside strategic lighting amplifies the space's warmth and depth.


Utilizing Vertical Space: The Staircase and Mezzanine
In duplex apartments, the staircase is not just a functional necessity but a significant design element. The Petit Gervais duplex uses the staircase to introduce texture and color contrast, reinforced by a full-height bookcase that merges practical storage with aesthetic appeal. This feature, typical in Duplex Apartment Interior Design, demonstrates how vertical spaces can be effectively utilized.

The Mezzanine: Maximizing Limited Space
The mezzanine level in the Petit Gervais duplex serves as a private retreat, distinct from the social areas below. This separation is a key component in duplex design, offering secluded space without sacrificing the apartment's open feel.


Bathroom Design: Privacy and Light
The bathroom's design in the Petit Gervais Duplex employs glass paving stones to create a private alcove that still allows for the passage of light. This approach to bathroom design in a duplex setting emphasizes the need for privacy while maintaining an airy and open ambiance.

The Essence of Duplex Apartment Interior Design
The Petit Gervais Duplex by AJAR exemplifies modern Duplex Apartment Interior Design through its strategic use of space, material, and light. This project illustrates how duplex apartments, often challenged by size constraints, can be transformed into bespoke, innovative homes that cater to the needs and aesthetics of their inhabitants.
Transforming a duplex apartment into a cohesive and inviting space requires a balance between functionality and style, as demonstrated by the Petit Gervais project. For those looking to redesign their duplex, this case study offers inspiration and insights into making the most of every square meter.
