When it does look light but it is heavy !
Sometimes it is a great trick play to the eye, the sort of magic trick, the different direction …. with this great concrete steps, which would be even more beautiful in marble or limestone. imagine a fine anstrude or clipsham. I was really amazed by the simplicity of the disposition of the treads, such a simple idea. I which some of the designer we work with would be more adventurous.
Maybe with more boldness we would manage to make this path from one floor to the other more exciting !
