South Africa’s Construction Outlook for 2025
The construction sector is projected to grow modestly in 2025, supported by public infrastructure spending, housing demand, and energy-related investments. Key areas expected to drive growth include:
-
Renewable energy (solar, wind, storage)
-
Road and transport upgrades under SANRAL
-
Affordable housing and mixed-use developments
-
Smart cities and green building technologies
The government’s Infrastructure Fund and the continued push for private sector participation in development are also likely to boost project pipelines.
