The short answer

Do you need planning permission for a loft conversion in Huntingdonshire?

Rear dormers and roof enlargements are normally permitted development under Class B, within volume limits, but Class B rights do not apply on article 2(3) land, which includes every conservation area. In Huntingdonshire this matters: the borough has 60 conservation areas and 6 Article 4 directions, and inside those the permitted development route narrows or is removed, so a loft conversion can need a full application where it would not two streets away.
