Brownfield land and private residential gardens - Public forum - Planning Advisory Service (PAS)

There are a number of other situations I would also like to hear members' view on: 1) Does this only apply to C3 use class or does "residential garden land" include sites currently in all C classes and Sui Generis residential uses such as hostels? 2) Does this apply to the conversion of ancillary garden buildings into new dwellings and ancillary annexes (which meet the monitorign criteria of a new dwelling), and the conversion of annexes into independent dwellings? My understanding was that this change to PPS3 to to steer housing development away from "green" residential gardens to prevent "garden-grabbing" but we need to be clear if we are protecting plot sizes, residential density or reducing built form footprints.

If the surface of a plot was once occupied by a school building, the building demolished and the area flagged over, and could not be regared as "having blended into the landscape in the process of time" neither does it appear to be part of the "natural surroundings", then would it remain brownfield under PPS3 definition.
