  • Residential construction costs increased 4.1% year-on-year, recording the strongest annual growth.
  • Construction and production costs remained under upward pressure due to rising labour costs and contractor rates, while building material prices showed increases in bricks and woods, stable pricing in steel and cement and declines in bitumen and metal products.
