An architectural stone mason generally works in the commercial sector, cutting to shape all natural stones (granite, limestone, sandstone and marble) by hand or with Computer Numerically Controlled (CNC) machines. There is a direct relationship between the nature and quality of the product required and the payment made by the customer. Therefore the stonemason has the responsibility to work professionally in order to meet the requirements of the customer and thus maintain and grow the business. The architectural stonemason works on heritage sites and in workshops. The work will range from basic places of worship to massive Gothic cathedrals, from simple but signiﬁcant buildings to the grand architectural and secular commercial and municipal buildings that deﬁne a country’s heritage.
