One of the few new pieces developed for the debut of LEGO Town was a new window frame, to which could be affixed both windowpanes and shutters. Initially, designers incorporated them only where one would expect a window to appear. However, they soon realised that the frame, especially, represented an opportunity. In 1980, a transparent sheet was created, intended to mimic a pane of glass, which could fit inside the existing frame. Together, these sheets could cover a 1x4x3 area more efficiently than filling that same space with bricks.

Glass windows were introduced to work with new window frames.
