In Prague, the capital of the Czech Republic, the architectural firm ra15 has completed the expansion of the Duhovka Montessori Primary School. Prioritizing functionality, the project strives to create spaces that stimulate concentration, a sense of comfort, and overall well-being, increasing the building's spatial capacity and significantly improving the comfort of students and teaching staff.

The intervention consists of an increase in the number of classrooms, an extension of the existing gymnasium, and the addition of new specialized spaces, including an art studio with a science lab and a multimedia room, which allow for flexible learning with an individualized approach that paves the way for an inspiring educational experience.

Considering the load-bearing capacity of the original building, the ra15 team opted to execute the vertical extension with a wooden structure. Wood, a key feature of the building's interior, used for both furniture and cladding, creates a warm atmosphere that encourages a sense of comfort and concentration. Additionally, the spacious openings allow natural light to enter while simultaneously connecting with the surroundings. On the exterior, both facades are clad with a framework of resistant metal sheets.

The Montessori method is based on the philosophy: "Help me do it myself," which encourages children's autonomy in the learning process. To respond to this philosophy, the project required a spatial layout different from that of traditional classrooms. Through open, flexible, and adaptable spaces, bathed in natural light, this project created an inspiring environment where learning positively impacts children's learning.

Project description by ra15 

Our environment significantly impacts our quality of life, and this is even more true for the spaces where we learn. Students at the Czech-English Montessori Elementary School Duhovka have now gained an improved learning environment with the expansion of a middle school and the enhancement of the service standards and comfort for students and staff. Throughout the project, functionality, and quality of space were key considerations.

The Montessori approach to education is based on the philosophy: “Help me do it myself,” which encourages children’s autonomy in the learning process. To fulfill this philosophy, a stimulating environment that meets children’s mental developmental needs during their sensitive periods is essential. However, this also places higher demands on space and its use.

Thoughtful Integration with the Surroundings
The new classrooms and the gymnasium extension were designed in response to spatial and urban planning constraints while minimizing the impact on nearby buildings. The third-floor extension was conceived as a single-story, recessed structure compared to the existing building footprint. The avant-corps and the gymnasium extension were adapted to be used as outdoor terraces connected to the corridor, an art studio, and a science lab.

A Space That Adapts to Children
The Montessori method requires a different spatial arrangement than traditional classrooms. Each pair of core classrooms is interconnected, allowing students to move seamlessly between them. This setup supports flexible teaching methods and an individualized approach to learning. The layout also aligns with the existing sanitary facilities, positioned between the core classrooms. Each classroom is equipped with personal lockers for students, a kitchenette for food preparation, and a relaxation zone for downtime. The rest of the space is kept open to allow for a variety of teaching approaches.

Wood, Metal, and Glass
Considering the load-bearing capacity of the original structure, the vertical extension was built using a wooden framework, which remains exposed in the interior. Wood is also featured in the built-in furniture and gymnasium cladding. In combination with glass, it plays a dominant role in the classrooms, contributing to ample daylight and excellent acoustics—creating optimal conditions for concentration and effective learning.

Both extensions’ facades are clad in durable metal sheeting. On the gymnasium, the metal panels resemble traditional wooden shingles, while on the classroom extension, they form vertical strips that transform into shading louvers around the windows, adding lightness and dynamic contrast to the robust contours of the original two-story building.

A Place for Creativity and Movement
The expansion ensured new specialized spaces, including an art studio with a science lab, a faculty lounge, and a multimedia room. The art studio and lab connect to the outdoors through two spacious side terraces, providing additional areas for teaching and creative activities. These spaces allow students to gain hands-on experience with carefully prepared equipment, a cornerstone of Montessori education.

The new gymnasium extension seamlessly links indoor sports facilities with the adjacent outdoor playground. Designed to open like welcoming arms to the garden, the flexible layout enables smooth transitions between indoor and outdoor activities—once again reinforcing the importance of interactive learning.

With its modern design, natural lighting, and adaptable spaces, this project has created an inspiring environment where learning becomes a joyful process of discovery.
