Sime Darby Property Bhd is developing a new affordable housing project, Harmoni 1, located in the City of Elmina, Shah Alam with a gross development value of MYR 155 million. The company would complete two prototypes of the D3 concept house by the middle of the year before pursuing the actual project in the third quarter. The D3 concept would reduce the completion period for construction in about 24 months as compared to 36 months to 42 months using the conventional concept.
