‘Craftsmanship is mastery’ used to be the slogan of a well-known brewer. And that slogan is entirely applicable to the work by contractor De Kok Bouwgroep and ZNR on the construction of the new winter storage facility on the Mattemburgh estate of Brabants Landschap. Because as beautiful as I can draw it out on paper, it all depends on the execution of the work. All work on the estate must be completed before the construction period so that the official opening can take place after the vacations.
