Belgium Faces Widening Housing Supply-Demand Mismatch in 2025

Belgium's housing market experienced a significant widening of the supply-demand mismatch throughout 2025, raising concerns among economic analysts. According to ING research, the country saw a sustained decline in building permits, which severely impacted the residential construction sector's output. This downturn was primarily driven by a slump in new apartment projects, failing to keep pace with shifting demographic needs. Simultaneously, there is a growing demand for smaller housing units that current supply levels are unable to satisfy. While the persistent shortage may support property prices and rental yields in the long term, it poses immediate challenges for construction volumes. Analysts suggest that the lack of new permits remains a primary bottleneck for the Belgian real estate market's overall health.
