All of our buildings are built with the same high quality materials. The difference is appearance and detail. If you look at the Standard buildings you'll see narrower overhangs, a basic trim package, and a low roof pitch.The Classic buildings have nicer trim along with a steeper roof and wider overhangs. Then the Premier buildings feature a sharper design with a steepest roof pitch possible, additional windows, and trim around the windows.
