Introduction
Buildner is pleased to announce the results of the Kinderspace Edition #3 competition, an international design challenge inviting architects and designers to rethink the environments in which early childhood learning takes place. The competition called for proposals that move beyond conventional educational models, envisioning spaces that support curiosity, independence, and holistic development through architecture that is both nurturing and adaptable.
Participants were tasked with designing an educational facility that accommodates young children across multiple age groups, alongside educators and support staff, integrating spaces for learning, play, rest, and interaction. The brief emphasized the importance of child-centered design, encouraging proposals that engage scale, materiality, and sensory experience while fostering a strong relationship between indoor and outdoor environments. Rather than treating education as a purely programmatic requirement, the competition sought to explore how architecture can actively shape developmental processes through spatial organization and environmental quality.
The diversity of submissions revealed several recurring themes. Many projects approached the kindergarten as a small community or village, breaking down the overall mass into clusters of intimate, house-like volumes that create a sense of belonging and familiarity. Others focused on the role of nature as a fundamental component of learning, integrating gardens, courtyards, and productive landscapes as extensions of the classroom. A number of proposals explored architecture as a pedagogical tool in itself, exposing materials, construction systems, and environmental strategies to make learning tangible and experiential. Across multiple entries, flexibility and adaptability emerged as key concerns, with spaces designed to evolve throughout the day and respond to different modes of play, teaching, and social interaction.
Following review by an international jury panel, prize winners and honorable mentions have been selected for their clarity of concept, spatial intelligence, and thoughtful engagement with the brief. Together, the selected projects demonstrate how architecture can support early childhood education not only through function, but through atmosphere, material presence, and the creation of environments that inspire exploration, imagination, and a lasting connection to the world around them.

UpCycle Garden proposes a vertically organized kindergarten embedded within the rooftops of a dense informal settlement, transforming underutilized surfaces into a network of learning, play, and community spaces. Rather than occupying scarce ground-level space, the project builds upward through a series of lightweight, modular interventions that connect adjacent roofs into a continuous educational landscape. Read more The spatial organization is conceived as a layered system of clusters—educational, social, and service spaces—interlinked by a dynamic circulation path that encourages movement, discovery, and interaction. Play becomes an architectural driver, with rooftops activated through climbing structures, gardens, and interactive installations that support both physical and cognitive development. The use of locally informed construction methods and recycled materials reinforces a low-impact approach, while phased growth strategies allow the project to adapt over time. By integrating urban agriculture, flexible classrooms, and communal gathering areas, the proposal seeks to redefine the kindergarten as both an educational environment and a catalyst for community engagement. The architecture operates as an extension of everyday life, reclaiming overlooked spaces to support childhood development, social cohesion, and environmental awareness.
I appreciate the designer's efforts to maximize the building area within a limited spatial envelope. The stacked solution, organized around three clusters, on the one hand facilitates morphological and contextual integration, but on the other leads to an unnecessarily complex plan structure. A childcare center generally benefits from a simple and readable model that focuses on ease of use and clarity.
Edward Weysen / Buildner guest jury

This proposal stands out for its inventive and socially grounded approach to sustainability. By reimagining existing rooftops within a dense informal settlement as active learning landscapes, the project transforms a constrained urban condition into an opportunity for growth, play, and discovery. The labyrinthine spatial organization encourages exploration and curiosity, allowing children to navigate a sequence of interconnected spaces that promote physical activity, social interaction, and experiential learning. The project’s most compelling contribution lies in its strategic reuse of existing structures. Repurposing rooftops not only minimizes the need for new ground occupation but also significantly reduces the carbon footprint associated with construction, material extraction, and land disturbance. Sustainability here is not treated as an applied layer, but as an embedded architectural logic—where adaptive reuse, lightweight interventions, and phased growth work together to create a resilient and low-impact solution. Beyond environmental metrics, the proposal demonstrates a strong understanding of social and educational sustainability. By integrating play, learning, and community life into a vertically layered system, the project reinforces the idea that sustainable architecture must also support long-term social value, particularly in under-resourced contexts.

The project balances playful forms, colors, and interactive structures with a serious and thoughtful consideration of light and circulation, all on a very challenging site. You get the sense that the children were truly the client, co-creating the architecture.
Jake Heffington / Buildner guest jury
...and other works, USA
In a block segment of an elongated parking zone stretching across several blocks in the Lower East Side of Manhattan, the authors propose a themed kindergarten, the Foodie Garden, instead of a football pitch. Inspired by the diverse lifestyles and food cultures of the neighborhood, and perhaps also by the metropolitan melting pot of cultures, early learning and experience spaces are created for children, giving hope that food production and preparation represent highly cultural contexts that should be learned and experienced with all the senses from an early age. Clearly structured, beautifully developed, and with dignified, serious interior design, the work represents a foundation for coexistence, communication, and intercultural understanding of humanity. An exciting farm-to-table project for everyday life that more than makes up for the loss of a hardball court.
Matthias Roller / Buildner guest jury
Dannien Roller Architekten + Partner, Germany
A thoughtful and context-sensitive proposal that transforms existing rooftops into playful, productive, and community-oriented spaces. The project is commendable for working with the realities of dense informal settlements through lightweight, incremental interventions rather than imposing a disruptive solution. Its integration of play, reuse, and urban farming creates a meaningful model for reclaiming overlooked spaces and supporting everyday community life.

Pixels
Jury feedback summary
Pixels proposes a kindergarten organized as a modular system of small-scale architectural units, forming a cohesive yet diverse learning environment embedded within the urban fabric of Vienna. Drawing inspiration from the spatial logic of the Naschmarkt’s historic market stalls, the project reinterprets this typology into a child-centered educational landscape composed of interconnected “pixel” volumes. Read more These units are arranged along a central axis, creating a clear and legible organizational structure while allowing for variation in scale, function, and atmosphere. Each pixel accommodates specific activities (learning, rest, play, or care) while collectively forming a rhythmic sequence of spaces that encourage exploration and interaction. The architecture emphasizes material warmth through the use of timber construction, soft natural light, and carefully framed views, producing calm and supportive interior environments. Courtyards and transitional spaces mediate between inside and outside, reinforcing the relationship between the building and its surroundings. Through its modular logic and contextual sensitivity, the project balances flexibility with clarity, offering a kindergarten that is both adaptable and deeply rooted in its urban and cultural context.
The typological proposal for the design is based on the single-storey sales booths of Vienna's famous traditional permanent market location. The design manages to seamlessly integrate a daycare center into an urban area surrounded by multi-storey buildings from the late 19th century, adjacent to the existing Naschpark park. The theme of pixels is somewhat misleading at first glance, suggesting a modular and technoid abstract interpretation of the building complex. In this loving interpretation, the children's space becomes an imaginative cluster of rooms. The eight different building blocks and their arrangement evoke associations with a child's wooden construction set from the turn of the 19th to the 20th century. Enlivened by children, educators, and parents at a human scale, a high degree of design and contextual quality is developed that is perfectly suited to the construction task and the genius loci, giving hope for its implementation.
Matthias Roller / Buildner guest jury
Dannien Roller Architekten + Partner, Germany
A clear and well-structured proposal that uses a modular “pixel” system to create a flexible and child-scaled learning environment. The project thoughtfully mediates between the lively public character of the Naschmarkt and the surrounding residential fabric, introducing rhythm, adaptability, and spatial diversity. Its careful attention to scale, material warmth, and playful spatial organization makes it both contextually sensitive and architecturally engaging.
Mona Vijaykumar / Buildner guest jury

3rd Prize Winner
Oasis of Halaqat
Competitions offer something that the academic studio, for all its value, cannot fully replicate — genuine stakes. Your work is seen and judged by people who do not know you, who have no context for your process, and who owe you no encouragement. For us as students, that exposure matters. It pushes us to be more deliberate, more honest, and more ambitious in our thinking.
Read full interviewJury feedback summary
Oasis of Halaqat proposes a kindergarten deeply rooted in the social, climatic, and cultural fabric of Siwa, Egypt, reinterpreting traditional forms of collective learning as the foundation for its spatial organization. The project draws from the halaqat system—informal circles of teaching often held in mosques or shaded outdoor spaces—translating this into a sequence of interconnected courtyards and clustered classrooms arranged along a linear spine. Read more Anchored by its relationship to the adjacent mosque, the proposal extends existing patterns of community life, positioning education as an embedded, everyday activity rather than a separate institutional function. A continuous canopy of lightweight fabric defines the project’s identity, filtering light, reducing heat, and creating a unified microclimate across indoor and outdoor spaces. The architecture employs low-tech construction methods and local materials, including kershif (mud and salt-based walls), ensuring both environmental responsiveness and cultural continuity. Elevated classroom volumes and shaded ground-level spaces allow for flexible use, supporting play, gathering, and informal learning. Through its integration of passive environmental strategies, vernacular construction, and community-based spatial logic, the project offers a resilient and contextually grounded model for early childhood education.
A sensitive and well-articulated intervention that responds to the social and spatial realities of its context. The project thoughtfully reinterprets traditional street life and public space through lightweight structures and shading strategies, creating a vibrant community environment. Its emphasis on climate responsiveness, adaptability, and everyday urban life makes it a compelling and culturally grounded proposal.
Mona Vijaykumar / Buildner guest jury

The presentation stands out for its ability to merge atmospheric visualization with clear technical explanation, producing a narrative that is both evocative and highly legible. The axonometric overview immediately establishes the project’s relationship to its urban and cultural context, while the continuity of the shading canopy becomes a strong visual and conceptual anchor across the boards. Read more Plans, sections, and diagrams are carefully composed, with clean linework that allows the organizational logic—particularly the linear spine and clustered classroom units—to be easily understood. The diagrams explaining environmental strategies and construction methods are especially effective, translating low-tech systems into clear, didactic visuals that reinforce the project’s feasibility. A warm and restrained color palette unifies the presentation, echoing the materiality of earth construction and filtered light. Perspective renderings successfully capture the lived experience of the space, particularly the interplay of shade, structure, and human activity. At times, the density of information across certain areas of the board slightly reduces the clarity of hierarchy, but overall the project achieves a compelling balance between conceptual depth, environmental intelligence, and visual communication.

Jury feedback summary
Tiny Explorers Village proposes a kindergarten conceived as a small, self-contained settlement of house-like volumes, translating the scale and familiarity of domestic architecture into a learning environment centered on exploration and autonomy. Read more Organized around a shared central playground, the project forms a compact yet articulated cluster where individual classroom units function as distinct “homes,” each tailored to specific age groups and activities while remaining visually and spatially connected. This arrangement creates a clear and legible plan that balances collective gathering with moments of retreat, encouraging both social interaction and independent learning. The architecture is grounded in a strong environmental agenda, combining timber construction, hempcrete insulation, and passive ventilation strategies to achieve a low-impact and healthy indoor climate. Material systems are deliberately exposed and didactic, allowing children to engage directly with construction processes through elements such as clay plasters and rammed-earth features. Interior and exterior spaces are closely intertwined, with sliding partitions and outdoor extensions enabling flexible use and continuous movement between learning and play. Through its integration of bioclimatic design, modular clarity, and hands-on educational principles, the project establishes a cohesive and pedagogically driven environment rooted in both sustainability and human scale.
Outstanding spatial and sustainability integration featuring a timber structure, hempcrete, and natural ventilation, includes clay plasters and child-built rammed-earth elements that serve as explicit teaching tools for environmental performance.
Eleni Kalapoda / Buildner guest jury
Embedded Climates Design Group, United States
The designers successfully translate the initial concept of the building as a cluster of small-scale homes into an efficient and readable plan. The building is organized around a central playground. Although this effectively results in an introverted layout, the designers succeed in allowing the different age groups to engage with the surroundings. Moreover, the open section demonstrates that the vernacularity of the basic concept enhances the technical execution of the idea.
Edward Weysen / Buildner guest jury

The presentation delivers a visually engaging and conceptually rich narrative, effectively combining analytical drawings with vibrant renderings that communicate the project’s playful and community-driven ambition. Read more Linework in plans, sections, and axonometrics is generally clear and consistent, allowing the vertical organization and clustering strategy to be understood, while the diagrams successfully explain construction logic, phasing, and rooftop expansion. The use of color is particularly strong, reinforcing programmatic differentiation and creating a lively visual identity aligned with the project’s educational intent. However, the overall graphic hierarchy is somewhat diffuse, with multiple diagram types and text blocks competing for attention across the board. Text provides a solid conceptual grounding, though its distribution and emphasis could be more strategically organized to guide the narrative more clearly.
