A few months ago we were excited about Concrete Legos as its ultimate stretch from childhood to adulthood. We recently discovered Ever Block and we think they deserve the same enthusiasm.
Ever Blocks are modular plastic blocks with a wide range of applications from room dividers to furniture and semi-permanent structures. Only their black blocks are currently manufactured in recycled plastic but the company has committed to continued research into recycled material; the blocks can be recycled but more importantly repurposed - your creativity is the only limit.
EverBlocks can be either purchased or rented - They are available in South Africa, check their contact page
Great innovations are adding so much magic to conventional building methods!
