Loft conversions change your roofline — and that makes them one of the more closely scrutinised application types. Councils scrutinise visibility, overlooking and street character more closely than for ground-level work. Here's what the data shows in Bromley.

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.
