The kit was very easy to assemble. However some of the pieces had some warpage to them. Clamps had to be used when gluing them but everything came out okay. It is a nice kit to add interior to. A floor can be cut in one piece. Then desks etc. can be added as well as window dressing.
Directions are easy and bldg fits together well. Details are accurate and fits well with my layout, which is a Whisky distillery. I have 2 of these bldg's and they are used as a machine shop and a welcome center. Did not use the furnace on either one. The paint used makes them look like different bldg's. Very happy with this product and highly recommend it.
