In 2020, Braintree District Council approved retrospective planning permission for a replacement dwelling at Black Notley, Essex, regularising a situation in which approved extensions had not been built as drawn and the original structure had been substantially demolished.
The case raised the legally significant question of when works to an existing building cross the threshold to constitute a new dwelling, requiring a fresh planning permission in their own right.
Retrospective Planning Approval in Braintree
Retrospective planning permission was obtained from Braintree District Council for a replacement four-bedroom dwelling at Black Notley.
Planning permission had originally been granted for extensions to the existing property.
During construction, however, the works departed materially from the approved plans: the original structure was substantially demolished in the process of building the extensions, raising an important legal question about whether what had been constructed could properly be described as an extension or whether it had in fact become a new building.
This question — at what point does demolition associated with extensions become the construction of a new dwelling — has been considered by the courts on a number of occasions.
The established legal position is that where the development results in a new building in effect, it does not matter that works were carried out to a pre-existing structure: the outcome may properly be regarded as a replacement dwelling rather than an extension, and a fresh planning permission is required.
The degree of demolition and the nature of the works must be assessed on the specific facts of each case.
In this case, a retrospective planning application was necessary to regularise the development as built.
The planning case demonstrated that the dwelling as constructed was of good design, met the National Described Space Standards, provided suitable rear garden amenity, and offered adequate off-street parking in line with the Council's adopted standards.
The application was transparent about the works that had been undertaken and the legal context, which contributed to a constructive determination process.
Braintree District Council accepted the case and granted retrospective planning permission.
