This is a great model. The way you are given three build options makes this a versatile building. I built this kit in three weeks working on it for about 30 minutes at a time. I would advise putting together the main walls first (main building and machine building) then painting them. I would also say tape up the inside of the window openings to keep paint out of the inside of the buildings. It does take some pre-planning to insure a good build. Other than that the kit was a pleasure to put together. Well worth the time and money!
