Here's a sketch of one design idea for the doors I'm working on for the front facade of the Griswold building. There will be 6 doors and each one is 9 and 1/2 feet tall x 3 feet wide. The idea is to use old lawnmower blades that I can get for free, cut them into pieces and bend them into the C shape to fill in between the bars. This metal grill will cover a large window in the center of the door. The door is not to scale, but the dimensions of the metal design are correct.
