Kale Developments operates as a subsidiary of Tri-Star Group Holdings and provides development Management services in the construction sector.
A Development Management subsidiary for Tri-Star Group Holdings called Tri-Star Development Services, was registered in 2007 to operate on the sole basis of managing construction developments on a Turn-Key basis – this differs from other Tri-Star subsidiaries in the sense that they perform the actual construction of property.
Due to the nature of the work and the increase in job opportunities, a calculated and strategic decision has been made to re-name the subsidiary in order to differentiate it from its parent company and construction companies. Hence, the name Tri-Star Development Services changed to Kale Developments on the 20th of March 2015.
