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 Hammersmith & Fulham.
See your ward's approval rate and nearby planning decisions — free and instant.
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.
