I was a bit shaky about my monument but since I've put a lot of thought into it I'm confident it'll still work well. The materials I chose were to reflect the architects and the monuments context at the same time. So for the outside (Herzog) I found they either use really course or really clean materials. Being a park, I went course and went for natural. I also thought that if it was Rammed Earth it would be quite significant because it would be hard to make. I made my own custom texture and used it for the outer shell.
For the clean inside Saarinen area, I used a custom texture from BENV1080, a polished concrete texture for the ground. This material is good for an outdoor area as well. The 4 sets of stairs would also be polished concrete as it would be easy to manufacture the slabs. The columns and details are white stucco because it's protective and a clean white finish, white paint or other materials I feel would deteriorate too fast in an outdoor community space. The benches are a higher polished concrete with a wooden table top.
