With the ongoing housing shortage in London, more than 2500 hectares of London's train, overground and tube lines could be freed up and used to build as much as new 300000 homes.
Sadiq Khan, the mayor of London, stated that the capital needs new 60000 homes a year to meet housing demand, but in reality only 2,917 homes were build in March , April and June, this year.
WSP director Bill Price said:
"As an industry we need to focus on radical solutions to overcome the housing crisis in our capital. Rail overbuild is not just about creating new homes, it’s also about creating new, safe, environmentally-friendly and vibrant communities that such developments can offer. They achieve the densification that London’s local authorities can use as economic development tools to provide growth, connectivity and jobs in the community".
