FENESTRATION: The arrangement, proportions, and design of windows, doors, and openings.


  • Creative expression with fenestration is not precluded provided the result does not conflict with or draw attention from surrounding historic buildings.
  • Windows and doors should be arranged on the building so as not to conflict with the basic fenestration pattern in the area.
  • The basic proportion of glass to solid which is found on surrounding buildings should be reflected in new construction.


  • Avoid window openings which conflict with the proportions and directionality of those typically found on surrounding historic buildings.
  • Avoid window pane patterns which conflict with those on surrounding historic buildings.
