My builder uses Houzz Pro to plan the timeline and give detailed estimates and daily updates with photos of progress, and provide invoices at pre-agreed key points in the build. This made the whole experience much more efficient and stress-free.
If you mean the 2 rectangular pieces, those were purchased from a to-the-trade showroom. I no longer have the information on those. Sorry! But they were patina-ed copper panels mounted onto a black metal 'box'. If you are referring to the wavy panel, those are by Advanced Technology and were finished with a copper metallic paint.
We desperately need to know where to get the artwork on the wall. We are in the scrap metal industry and want to incorporate copper and brass into our home, even if it's faux.
For a very similar aesthetic, see thermoplastic wall panels by Fasade. This might even be them. They have quite a variety of colors/textures, and will send samples.
