21 Wrench Road Industrial Development in Isando, near OR Tambo International Airport was undertaken as a speculative building in line with Redefine’ s executive statement which looks at specific initiatives that are energy efficient; resource efficient and environmentally responsible. It is a building that significantly reduces or eliminates a negative impact on the environment and its occupants which also embraces the concept of sustainable development.

Like in any warehouse design careful consideration was given to balancing the cost of the floor and practical use of the racking making sure the floor can withstand the loadings while making full use of the 14m unrestricted roof clearance, which still had to accommodate a range of potential tenants.  This needed to be a reasonable and practical choice –  while still providing tenant flexibility.
