I originally ordered this building thinking that it was a built up product. I was disappointed when I thought I had to build a kit, but I found building the kit was easy and gave me a chance to personalized it to my ideas. The hydrocal is easy to work with only a bit of sandpaper to clean the edges. The wall signage was simple to adhere with only a little Elmer's glue. The process taught me how to add details to this building and I have used that knowledge to do some scratch buildings myself. Would be nice to have some interior detail although I created some myself. Good kit1
