Mate en verhoudings of 'ontwerpe' van vrystaande mure word gewoonlik volgens die empiriese reëls wat in die Nasionale Bouregulasies vervat is, beiaal. Hierdie benadering kan egter beperkende en onekonomiese resultate lewer. Om die ontwerp van vrystaande mure te rasionaliseer is ontwerpkodes, soos vervat in die Nasionale Bouregulasies, gebruik om 'n wye reeks muurhoogtes en stutkolomrangskikkings vir mure met of sonder 'n vogweerlaag te bepaal. Die strukturele tekortkominge van die Nasionale Bouregulasies se klousules oor messelbouwerk word ondersoek, sowel as die invloed van stutkolomrangskikkings op die sterkte van mure.

Free-standing masonry walls are generally proportioned or 'designed' in accordance with empirical rules contained in the National Building Regulations. This approach can be both restrictive and uneconomical. Design charts, based on the codes of practice as listed in the National Building Regulations, are presented for a wide range of wall heights and pier configurations for walls with and without dampproof courses in order to rationalize the design of free-standing walls. The structural shortcomings of the walling clauses of the National Building Regulations are examined as well as the influence of pier configurations on the structural strength of walls.
