Thanks Karina.
Well, this building is actually not originally modelled in SU, it was modelled in Blender and painstakingly converted into a "component-driven" SketchUp model - mostly because it had many reversed face issues due to the conversion process from Blender file to .obj format.
Also, it's not actually that accurate of a model, in the sense that the real museum is so mind-blowingly complex. It has hundreds of fine terra cotta details including monkeys and birds, etc. Check the link at the beginning of this thread to find out more.
I hope to visit the building one day. I unfortunately missed it on my last trip to London.
The brick walls and diamond detail columns are a rough approximate of the "real thing".
