qb is a modular playground concept inspired by two classic childhood table games, Cuboro and Georello, reimagined at an architectural scale to transform cube-based play into a spatial experience for children. The qb block is a cube composed of five interconnected walls, built from a combination of pine plywood and transparent plastic panels, with changeable climbing grip placements and an internal network of stainless-steel tubes, slides, and pathways that allow children to climb, slide, and navigate the structure.
Conceived as a maze-like, interactive environment, qb offers long-term adaptability and gives playground companies the freedom to create countless configurations from a single, rearrangeable system of modular blocks.

Cuboro is a modular wooden marble run game created by Swiss engineer Matthias Etter (1986), which lets children combine wooden blocks in different configurations to build their own marble run systems.

Georello is a colourful gear construction game created by Italian company Quercetti (1990s), it introduces basic mechanics and interlocking gear combinations to children through hands-on building.

The qb playground was inspired by the marriage of the logic of Cuboro and Georello, translating their modular and interlock building principles into a life-scale children’s playground system of five-walled cubes with interchangeable fitted panels that form tunnels, slides, and climbing walls.
This flexible block system allows companies to reconfigure playground layouts regularly to keep children engaged, while reducing design, production, transport, and installation costs through a standardised modular approach.
