Government's plans to build homes in 'Europe's Silicon Valley' at risk of subsidence before work even begins
Briefly

The planned construction of 4,500 new homes in the Oxford-Cambridge growth corridor is facing scrutiny over subsidence risks linked to gault clay soil. This soil's tendency to expand and contract presents significant stability issues, especially in the context of climate change, which exacerbates risk by increasing the frequency of extreme weather conditions. A new study by Aviva indicates a notable portion of recent homes are built in flood-prone areas, raising concerns among residents about the safety and insurability of their properties. This situation casts doubt on the broader goal of establishing the region as a leading economic hub.
Thousands of new homes planned for construction in the Oxford-Cambridge growth corridor could face serious subsidence risks, potentially leaving future homeowners with uninsurable properties.
Analysis of British Geological Survey data suggests that areas within the corridor are highly susceptible to ground movement due to the presence of gault clay.
Home insurer Aviva reveals that one in thirteen (8%) new homes built in England in the last ten years are in a flood zone, the equivalent of almost 110,000 homes.
Climate change is exacerbating soil instability, leading to unsound foundations in homes and increased concerns for new build residents regarding flooding and subsidence risks.
