Eco-friendly and green ideas become more and more actual and popular because nowadays it’s very important to take care of nature and let it integrate modern life. Caroline Brahme was awarded for creating Grey To Green – it’s a series of paving stones that can “host vegetation”. These paving stones would bring more greenery to any city, will make it cuter and will integrate green structure into the city look, let it function properly. Grey to Green paving stones allow for customization and integration of greenery on the paved urban floor. Just imagine – you would walk like in the country, on the grass!
