Budapest schoolyard transformed with vertical play garden
Studio KRAFT reimagines limited school space as multi-layered learning landscape in dense urban district
1Schoolyard transformation in dense urban fabric
The concrete courtyard of Bajza Elementary School in Budapest's densely built 6th district was transformed into a multi-layered play and learning space by Studio KRAFT and Open Air Design. The 800m² area, previously used only for sports, was redesigned to accommodate over 500 students. Supported by Terezváros Municipality, the project vertically maximizes limited school grounds through innovative spatial strategies while preserving the central activity zone.
2Spatial multiplication through timber structures
Architects tripled usable space with modular wooden structures placed along the courtyard edges. Elevated platforms, climbing routes, and shaded nooks create zones for quiet activities while maintaining the central sports area. The design features 15 distinct play stations enabling 7 activity types throughout the school day. All structures were built using 100% recyclable materials, with load-bearing elements supporting up to 30 children simultaneously.
3Participatory design process
The six-month design process involved teachers and 120 students aged 9-12. Forty-five surveys and eight workshops directly informed spatial organization. Based on children's input, a 25-seat outdoor classroom was incorporated for extracurricular learning. The design includes climbing walls and suspension bridges to support physical development, with accessibility features for differently-abled students.
4Living infrastructure integration
Over 120 plants from 18 native species soften the previously hardscape courtyard. Vine-covered timber structures provide seasonal color variation. Special permeable surfacing absorbs 60% of rainwater, reducing urban heat island effect. The project holds Hungary's first Biophilic Design Certification for schoolyards, with insect hotels and bird nesting boxes enhancing biodiversity.
5Contemporary intervention in historic context
Structures complement the 1897 school building using traditional Hungarian wood joinery techniques. Platforms built above service areas created 350m² additional space without compromising ground-level openness. Circular openings and mesh panels introduce contemporary elements that dialogue with the historic fabric while ensuring visual connectivity across the courtyard.
6Multi-functional spatial strategy
The design accommodates varying age groups' needs throughout the day. Morning play stations for 1st graders transform into social spaces for 5th graders at lunch, then community gathering spots after school. Acoustic panels reduce noise pollution by 40%, allowing simultaneous activities. Movable furniture enables weekly reconfiguration by student committees.
7Model solution for dense cities
The project presents a replicable model for schoolyard transformations in high-density urban areas. At €1200/m², it delivers 65% more user capacity than conventional layouts. Studio KRAFT reports students' daily physical activity increased from 45 to 75 minutes post-implementation. Finalist in the 2023 European Architecture Awards' Public Space category, the design has inspired 12 similar school projects across Europe.
8New paradigm for educational architecture
Vertical Play Garden demonstrates how flexible spaces can address 21st-century learning needs. Unlike traditional uniform schoolyards, it offers multi-layered experiences fostering creativity, social skills, and nature connection. The project proves participatory design's value in urban interventions, with pre-post studies showing 82% increase in student satisfaction and 37% reduction in playground conflicts.
