Local families have been left to live in claustrophobic and sub-standard conditions as a result of flawed Government planning policies. 1,386 homes have been built under relaxed conversion to residential rules (Permitted Development) in Barnet and Camden since 2013, according to London Development Database figures obtained through a written response from the Mayor of London. Analysis of this data has also shown that none of these homes were affordable. Local London Assembly Member, Andrew Dismore AM, is calling upon the Government to urgently scrap Permitted Development rights, saying the priority should be to build the genuinely affordable and decent homes Londoners actually need.

Permitted Development rules allow developers to convert certain office and industrial buildings to residential use without going through the full planning process, in an aim to speed up the delivery of new homes. These conversions are also exempt from having to adhere to minimum space standards laid down by the Government.

Energy Performance Certificate (EPC) data, has been used to identify the floorspace of 193 of the permitted development homes built in Barnet and Camden since 2013. This has revealed that 40 of these flout minimum space standards.

London requires 65,000 new homes a year, according to the New London Plan, with 65% of these needing to be affordable. However, of the 15,929 homes built across the capital through Permitted Development conversions since 2013, only 71 were affordable – accounting for just 0.4%.

Last Autumn, the Government consulted on proposals to extend Permitted Development to allow a wider range of high street uses to be converted to homes without planning permission. The Government also proposes to give Permitted Development Rights to the full demolition of commercial buildings to be rebuilt as residential properties.

Local London Assembly Member, Andrew Dismore AM, said:

“This flawed Government policy is hampering the efforts being made to tackle the acute housing crisis faced by Barnet and Camden.

“Permitted Development doesn’t offer a solution to housing shortfall, it just forces families into full price, sub-standard, rabbit-hutch homes.

“Government plans to extend further Permitted Development Rights are extremely concerning and could lay the groundwork for the slums of the future.

“Planning standards have been put in place for a reason, and our priority should be to build the thousands of genuinely affordable and decent quality homes that Londoners need. All the evidence suggests that the Government need to scrap this policy as a matter of urgency”.

Notes

• 1,386 homes have been built under relaxed conversion to residential rules (Permitted Development) in Barnet and Camden since 2013, according to London Development Database figures obtained by Londonwide Assembly Member, Tom Copley AM, provided in a written answer from the Mayor of London;

• Permitted Development Rights were introduced in England in 1995, and allow certain changes to be made to a building without requiring full permission from the Local Planning Authority. Originally, these were intended to be used for minor modifications, such as installation of porches, fences, satellite dishes or solar panels, while also including extensions of homes. Since 2013, these rights have been expanded considerably. In May 2013, legislation came into force which would allow conversion from office (use class B1(a)) to residential (C£) without full planning permission. With this also came the introduction of Permitted Development Rights to convert some light-industrial buildings (for example, small workshops) to residential as well. Developers make an application through a “prior approvals” process – and the local council is not able to hold a scheme to the criteria set out in its Local Plan, or those set in the Mayor’s London Plan, as it would for any other typical development. The authority may take into account impacts on highways and transport, the impact of noise from nearby commercial premises, but the converted dwellings do not need to meet minimum size standards or provide affordable housing;
