Hi folks, long time lurker here.
I thought I would bring to your attention a Kickstarter of a company that I have bought things off in the past.

The actual company can be found here:

I'm planning on getting hold of some of the bigger ones, putting flat roofs on them and using sci fi bits to make them look a bit like the buildings in Blade Runner. Obviously their intended purpose is for many periods historically.
Worth a look at the images on the facebook group, I have used the hesco and the sci fi detailing kits and they are lovely.
