The integration of residential apartments, affordable housing, commercial office space, retail, and premium amenities within a single 40-storey mixed-use development, presents considerable scope management complexity. Each functional stream carries distinct compliance obligations, fitout specifications, and operational requirements, necessitating meticulous cost planning and coordination. Additionally, the inclusion of 30 affordable housing units within a premium residential context further compounds this challenge, as these dwellings are subject to strict cost caps, design standards, and funding conditions linked to government or social housing programs. With a diverse stakeholder group, there is a critical need for transparent cost communication, rigorous budget alignment, and strategic value engineering.
