Cathedrals are large buildings used for Christian worship and are located worldwide. Cathedral sites, size and layouts often have symbolic considerations. Floor plans are considered to be the first step in construction, and are the determinations of building designs which follow. This paper suggests a range of simple geometric methods to create repeating pattern alternatives suited to textile and similar end uses. Based on reference to cathedral floor plans, these methods include: various square-based and golden-section-based constructions; root-two rectangles and modular combinations.
