This analytical feature would explore one of the most nuanced debates in Hampstead planning: how to achieve ambitious sustainability goals within the constraints of conservation area designations. Drawing on the Hampstead Neighbourhood Forum's March 2025 AGM discussion, the article would feature Susannah Hagan, Emeritus Professor of Architecture at the University of Westminster, who spoke eloquently about the balance between sustainability and conservation. Her provocative photograph of Chester Cathedral's roof covered in solar panels would serve as a central image, challenging assumptions about what heritage protection permits. The article would explore the Forum's strengthened policies promoting retrofitting and sustainable design, distinguishing between "fabric-first" approaches focusing on insulation and airtightness versus more expensive "deep retrofit" strategies.
