About the Window Frame design

The big central opening is a square with its four corners notched away, leaving a stout white cross with stepped shoulders. Around it, a ring of long slots runs along each side and meets a grid of four small squares at every corner, where the bars cross over one another. The outer band repeats the idea at a larger scale, with three short windows on each edge and a wide L-shaped opening folding around each corner.
