Why loft conversion approval rates matter

Loft conversions face more scrutiny than rear or side extensions because they change the property's profile from the street. Dormers, mansards and hip-to-gable alterations are particularly sensitive.

These are council averages. Your property is specific.

Two houses on the same street can get different outcomes.
