The London Development Database (LDD) records significant planning permissions in London.
The data is entered by London's planning authorities, and is checked by the GLA to ensure consistency across London. The LDD records any planning consent that permits one or more of the following:
New permissions are added to the database on a monthly basis within three months of the end of the month in which they were granted. Information on scheme starts and completions is updated annually by September the following year.
The spreadsheet LDD - Planning permissions includes details of all permissions either currently recorded as live (not started or under construction) or completed since 01/04/2006. LDD - Non-residential floorspace provides additional details of the non-residential floor space for those permissions with a non-residential component and LDD - non-residential bedrooms provides additional details of the non-C3 bedrooms over the same time period.
