some times its a little bit hard to decide about design and material because of many factors are in the projects. i have tested the material of facade with random colors (5 colors) for each element randomly, the result was exciting but its not match to site and the other elements of project.it doesn’t have harmony. so i decided to created in one material.
one is simple bronze with noise of overall shape, and the second which i choose is the complex of 4 materials with variation of color. but they are same material.
here we can see the results.
