Two out of three large families in Belgium are finding it difficult to secure adequate housing, according to a report by the Belgian daily Le Soir. The finding places Belgium at the centre of a growing European housing crisis, a theme reinforced by Portuguese Prime Minister António Costa, who called for a coordinated EU response during a high‑profile speech in New York.
Scale of the problem in Belgium
The Le Soir investigation highlights that roughly 66% of households classified as large—typically families with multiple children—are experiencing significant obstacles in the search for a home. The newspaper cites rising rents, a limited stock of family‑size apartments, and long waiting lists for social housing as key contributors. While exact figures on vacancy rates were not disclosed, the report underscores that the shortage is most acute in the densely populated regions of Brussels and Flanders.
"Nearly two out of three large families in Belgium are struggling to find a home," the newspaper wrote.
Housing officials in Belgium have acknowledged the pressure on the market, noting that recent construction has not kept pace with demographic trends. The federal government, together with regional authorities, is said to be reviewing policy tools such as rent control measures and incentives for developers to build larger units, though no concrete timetable has been announced.
EU‑wide concerns voiced in New York
At a forum in New York, Prime Minister António Costa used Belgium’s predicament to illustrate a broader continental challenge. Speaking to an audience that included European Union delegates, Costa urged member states to develop a joint strategy to address the affordability gap, especially for families with higher occupancy needs. He emphasized that housing instability threatens social cohesion and economic mobility across the bloc.
While Costa’s remarks were not accompanied by a specific legislative proposal, the Portuguese leader called for enhanced data sharing, coordinated fiscal incentives, and a harmonised approach to cross‑border housing finance. According to the Portuguese outlet Demócrata, the speech aimed to galvanise EU institutions ahead of upcoming discussions on the European Pillar of Social Rights.
European officials have previously signalled interest in a unified housing agenda, but progress has been uneven. The European Commission has launched a series of studies on housing market dynamics, yet member states retain primary responsibility for land use and construction regulations. Costa’s appeal therefore spotlights the tension between national sovereignty and collective action.

Analysts note that Belgium’s situation may serve as a bellwether for other EU nations facing similar demographic pressures. Countries such as Spain, Italy, and Germany have reported rising household debt linked to housing costs, and many urban centres report shortages of affordable family‑size dwellings.
In the short term, Belgian advocacy groups are urging the government to accelerate the release of pending construction permits and to expand the allocation of social housing to larger households. Long‑term solutions, experts argue, will require a blend of policy reforms, investment in new supply, and mechanisms to protect renters from price spikes.
As the EU grapples with a housing affordability crisis that transcends borders, the plight of Belgium’s large families may become a focal point for collaborative policy‑making, echoing the call made by Costa in New York for a unified European response.
