I didn't finish texturing them - I'd post WIPs for download but the machine the files are on is bricked, and I haven't found time to pick through its hard-drive yet '^_^
If you want to try something similar yourself, my process for things like this is pretty simple:
- Greybox in Sketchup (look for the free 2017 desktop version - works great, easy to learn, ideal for simple geometry)
- Export as Collada files, import into Blender, group into objects, then use 'Smart Project' to get UVs
- Head to Screaming Brain Studios for textures (consider tipping the bellhop while you're there, they do God's work)
- Rotate/stretch/wiggle your UVs around on them until things 'look right'
