Modular traditional staircase

A method of constructing a stairway comprising the steps of:

• selecting a predefined stringer having a relatively planar, flat, module-supporting top to match a desired rise and run for a stairway;
• placing the stringer in position relative to a structure;
• anchoring an initial step module substantially horizontally adjacent and on the downstairs side of a lower end of the stringer to define an initial riser and tread for the stairway, and to define an initial stop, the initial step module including an integral block that is configured to abut the lower end of the stringer to insure proper alignment of the stringer relative to the initial step module;
• providing an intermediate step module that defines a riser and a tread for the stairway when placed on the stringer;
• supporting the intermediate step module on the module-supporting top of the stringer, and then placing a downward force on the intermediate step module thereby forcing the module along the top of the stringer into firm contact with the initial stop of the initial step module and insuring proper alignment of the intermediate step module to the initial step module;
• and
• anchoring the intermediate step module to the stringer.

A modular stairway comprising:

• a stringer having a relatively planar, flat top;
• an initial step module fixed adjacent a lower end of the stringer, the initial step module including an upper edge;
• a first intermediate step module attached to the stringer so that a portion of the first intermediate step module bears against the upper edge of the initial step module;
• wherein the stringer has a lower end that is vertical when the stringer is positioned for use in the stairway, the initial step module has an integral block for abutting the lower vertical end of the stringer so that the initial step module may be attached to the stringer, and the integral block for the initial step module supports the tread of the initial step module substantially directly from a floor underlying the initial step module.

A modular stairway comprising:

• a stringer having a relatively planar, flat top;
• an initial step module fixed adjacent a lower end of the stringer, the initial step module including an upper edge;
• and
• a first intermediate step module attached to the stringer so that a portion of the first intermediate step module bears against the upper edge of the initial step module;
• and
• an upwardly facing elongate channel defined on the stringer for receiving an edge of a wall covering material.
