KUALA LUMPUR: Sime Darby Property's first Divergent Dwelling Design (D3) sustainable homes project will commence in the third quarter this year. The D3 concept involves pre-fabrication and mass production of components for residential units that enables cost savings, higher product quality, reduction of on-site labour and minimised wastage. The concept reduces construction time from 36-42 months to 24-30 months, which is 28-33% faster than conventional methods. Named Harmoni 1, the D3 pilot project will be located in Elmina West at the City of Elmina, Shah Alam and will be the developer's first statutory affordable housing project to adopt the D3 concept. The project comprises 562 apartment units sized between 900 sq ft and 1,000 sq ft, complemented by shop office units with a total gross development value of RM155 million.
