Unlimited-Box / Concept for public spaces


Unlimited-Box can be used in many occasions, such as bus stops, market vendors, exhibition spaces, etc. It’s easy to use and diversified, it can even use solar energy to save electricity.

This design expands into the useable space with the smallest volume. It also provides some small box that can be seated, and can even be stacked to form a countertop for use.

Solar panels on the top can absorb sunlight and change into electricity to provide lights for use at night. It uses recyclable materials as much as possible. In addition to reducing the amount of waste, recycling can also reduce costs for the environment and consumers.
