Greatland Sugar Refining is a very well done kit from Walthers. Assembly was straight forward and uncomplicated and the instruction were well written and easy to follow. The 3 structures included in the kit make an impressive industry. Of course the structures could be used separately or in any combination on a layout. One feature that I thought was especially nice was the inclusion brick inserts that can be used in place of windows on the main building. I created a random placement of windows to add some architectural interest. All-in-all a very satisfying purchase
