Truly beautiful. I searched for the photo online and came up with the designer info. With a large international firm like this there was likely a whole team devoted to the project, so perhaps the person who saw your inquiry didn't have the information to share and was likely too busy to spend time looking it up.

When I look at the panels, I see that they are completely flat so they are not moulded out of a material. I believe they would have been cut by a C & C machine which is guided by a computer. I don't know what the material is but it could be some sort of composition material that's super smooth and takes the painted finish very well. I wish I could tell you more. If I were working on your project, I would do more research and likely turn up some useful information :)
