Checkered Playroom is a lightweight prefabrication building product highlighted with exquisite looking and spatial quality, rapid assembling, reliable structural safety, high comfortability, under reasonable price. It is a synthesis product integrating playground, house, furniture and toy into one. The delicate building provides extraordinary environment to inspire children to exert their potential to explore and play.

“Provided the toys and teaching kits are cleared, can a classroom still attract kids to stay?”

STRUCTURE & safety

The components of Checkered Playroom are made with Structural Insulated Panel, composed in 3 directions to form a stable open box module. When the boxes are connected, an equivalent of waffle spanning structure is formed. Structural stability is guaranteed from unit level to building level. Not any toxic volatile material is used in the Checkered Playroom to make certain healthy interior is provided for the children.


Several strategies are applied to ensure outstanding thermal performance. Direct thermal bridge is prevented in the component and building design. All component panels are filled with insulation material. Building is lifted up from ground to reduce undesirable emission of heat to the subsoil. Windows and doors on different facades allow flexible control of natural cross ventilation.

green architecture

Checkered Playroom achieved green architecture from different aspects. Minor ground treatment is required to support the lightweight building, hence to protect the soil from permanent damage. Zero construction waste is produced as all components are prefabricated in factory. The Checkered Playroom could be deconstructed and reassembled in different locations, allow maximum flexibility in unpredicted future.
