Questions
A single-storey rear extension can extend up to 8 metres beyond the original rear wall of a detached house, or 6 metres for other houses, and be no more than 4 metres high. It isn't available on article 2(3) land, such as conservation areas, or on a SSSI.
Yes. The council notifies the owners or occupiers of adjoining premises and gives them at least 21 days to make representations. If any of them objects, prior approval is needed on the impact on their amenity.
42 days from receiving your notification. If it doesn't tell you within that time whether prior approval is given or refused, the extension can go ahead in line with what you submitted.
