Learn More About Us

Kale Developments’ key objective is to provide clients or investors in the property sector with a comprehensive “one stop” development management service. From project inception, land acquisition and assembly, professional appointments, design development, feasibility study, financial structuring, funding, construction and ultimately project close out.

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.
