Why construction alone won't solve housing crisis

By the Editorial Team · Saturday, July 25, 2026

London continues to face a housing affordability crisis exacerbated by a high number of empty properties and insufficient support for younger, lower-income residents despite ongoing new construction efforts. Experts warn that without addressing vacancy rates and investment-driven housing stock, increasing supply alone will not resolve affordability issues or prevent broader social impacts such as declining birth rates.

A growing number of London residents continue to struggle with housing affordability, prompting renewed debate over potential solutions to the ongoing crisis. While increasing the supply of new homes is often presented as a key remedy, recent analysis suggests that construction alone may not resolve the challenges faced by many, particularly younger adults at the start of their careers.

One concerned Londoner in her thirties, who chose to leave the city partly due to difficulties in securing independent housing despite full-time employment, highlighted these complexities. She referenced a recent argument by analyst John Burn-Murdoch, who advocates for housebuilding as the primary solution to the crisis. However, Burn-Murdoch acknowledges that new construction will not sufficiently assist the city’s poorest residents—those with limited savings and financial stability. This group often remains unable to move out of family homes, perpetuating barriers to independent living.

Further complicating the housing market is the issue of significant numbers of empty properties in London. Official data cited in a June report from London City Hall projects that by 2025, over one hundred thousand residential units in the city could be unoccupied at any given time. In 2024, approximately 25,000 homes were recorded as being empty for a year or longer. Notably, only about 12 percent of these vacant dwellings are managed by local authorities.

The report identifies several factors contributing to this high vacancy rate. One is the phenomenon known as “buy to leave,” where newly built properties are purchased as investment assets and remain unoccupied. Additionally, student accommodations and purpose-built rental homes frequently experience slow letting rates, resulting in numerous newly developed dwellings standing empty.

These findings challenge the notion that simply building more homes will effectively address housing shortages. With a portion of the housing stock remaining unused, strategies may need to expand beyond construction to include policies targeting vacancy reduction and improving affordability for younger and lower-income residents. Some experts suggest that without tackling these underlying issues, additional supply risks exacerbating investment-driven vacancies rather than alleviating the lack of accessible housing.

The interplay between housing availability and economic factors also influences broader demographic trends. The ongoing housing affordability problems have been linked to falling birth rates, as younger adults delay or forgo having children due to financial insecurity. This connection underscores the complex social implications of the housing crisis, extending beyond shelter to affect population dynamics and urban development.

In sum, while increasing housing supply remains a critical component of addressing London’s housing issues, it appears insufficient on its own. A multifaceted approach that considers vacancy patterns, investment incentives, and the specific needs of younger and less affluent residents may be necessary to create meaningful and lasting change in the city’s housing landscape.
