I'm in the UK too. Vancouver's a bit too far to go to check those details, isn't it?

I'm modeling in Anim8or, though the renders were done in Vue 4. I'm not doing anything very clever, something very inelegant and inefficient in fact! I'm building it as the builders did, in modules - see image. Takes a lot of calculator bashing and a hell of a lot of work in naming and grouping elements, also results in a lot of redundant facets. It's an approach that does give the ability to easily hide portions from the renderer, equally it's a nightmare to texture though!

Thanks for the nice comments, and let me know if you emigrate to Canada. I suspect this could take some time :-) John
