Sadiq Khan's potential strategies for constructing an additional 250,000 homes detailed out.

In an innovative plan aimed at addressing London's growing housing crisis, a proposal has been made to store London's underground trains underground and utilise the vacated spaces for housing development. This ambitious plan, if implemented, could potentially yield upwards of 250,000 new homes in the city.

The proposal suggests that by moving the tube trains underground, the issue of graffiti could be significantly reduced, as trains would be out of sight during the night. This idea is part of a broader strategy that seeks to make the most of London's limited space.

London's tube network is extensive, with over 1,000 trains zooming in and around the city each day. At present, most of these trains go to sleep in a shed somewhere overnight. Notably, TfL's Neasden depot, which stores Metropolitan and Jubilee line trains, spans 64 acres. There are over a dozen similarly-sized TfL and Network Rail depots across London.

The cost of moving all these London train sheds underground is estimated to be in the region of £8-10bn. This figure does not include the cost of the Bakerloo line upgrade, replacing the Central line stock, or funding Crossrail 2.

The proceeds from selling the new build homes could net Transport for London (TfL) upwards of £50bn. These extra funds could be used for the upgrades of the Bakerloo line, replacing the graffiti-addled Central line stock, or funding Crossrail 2.

The sites proposed for building homes would have great transport links, making them highly desirable for potential residents. However, the politician who proposed this plan remains unidentified in the search results.

London's need for new housing is growing more acute. Fewer than 1,000 homes were built in London in the second quarter of this year. Sadiq Khan's current strategies for housebuilding are not effective enough to meet the city's demand.

The proposal for building over 250,000 homes in London involves burying the tube trains underground. This approach references the Westfield model, a successful example of urban regeneration in London. If successful, this plan could significantly contribute to London's housing market and help alleviate the city's housing crisis.
