Woolworths wanted to provide a sustainable and educational way for families to play. So UNGA’s designers managed the impossible: turn the Woolworths store into a realistic green supermarket made of sustainable bricks. Putting sustainability at the heart of the decision-making, the bricks were made out of at least 80% recycled materials, including old fridges and swimming goggles, and received the Good Environmental Choice Australia (GECA) certification. Shoppers could collect up to 40 bricks sets to complete their Woolworths store, in addition to Starter packs, 2 trucks and figurines.
