Hi. The textures come from real pictures of the pavilion. That are the real walls. I found the chair on internet by free (it is very famous chair). What I could not find was the sculpture. https://www.google.com.au/search?q=scul ... 58&bih=798
Indeed, arguably the most famous chair in the world. And some of those famous furniture designs often exist in affordable replicas. And there will be an abundance of 3d models for SH3D to visualise.
Sculptures are harder to make, of course. While you could fake them with a transparent box and back front images (see this thread), that would sort of be a violation of your Pavilion design.
