My London Plan has a clear objective that Metropolitan Open Land should be afforded the same protection as Green Belt and protected from inappropriate development. The National Planning Policy Framework does allow development on protected open space if very special circumstances can be demonstrated.
The number of planning permissions involving construction that would lead to a loss of Metropolitan Open Land by year over the last five years for which the data is currently available are as follows:
These statistics include permissions on previously developed open space and for uses that are ancillary to the primary use as open space, such as sports facilities. They may also include improvements to existing or adjacent open space, including greater public access.
The data is derived from the data in the London Plan Annual Monitoring Reports and is not available at a more granular level. We also do not hold data prior to these years in a format that would enable an accurate answer to be given. However, looking forward, the new Planning London Datahub will enable more accurate and detailed analysis of such issues.
