Summary of the latest Permitted Development changes - May 30th
Extensions to Buildings in Class A Use [Part 42, Class A]
This temporary increase in PD rights only applies to Class A1 & A2 uses, even though Class 42 as a whole
applies to all A-Class uses.
The floorspace limit for additions to the original building is increased to 100m² or 50%, whichever is the
lesser [previously it was 50m² or 25%], unless the premises are in a SSSI.
The current restriction on extensions not being within 2m of a boundary is lifted for the temporary period,
subject to it not being next to a C-Class [residential] use, within a SSSI or on Article 1(5) land.
Again, the developer must give the LPA notice of the completion of the extension works, providing details of the
date of completion, and a description of the building works, including its location and dimensions.
