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:
any new build residential units
any loss or gain of residential units through change of use or conversion of existing dwellings
creation of seven or more new bedrooms for use as either a hotel, a hostel, student housing or for residential care through new build or change of use
1,000m2 or more of floor space changing from one use class to another or created through new build or extension for any other use
the loss or gain or change of use of open space.
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as live (not started or under construction), completed since 01/04/2006 or permitted since 01/04/2006 and subsequently superseded or lapsed. 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.
