Why it was refused

  1. The proposed development, including dormers, a front rooflight and internal alterations, would result in less than substantial harm to the significance of the listed building, its group value, and the character and appearance of the conservation area. This harm would arise from the over-dominant and unsympathetic design, causing visual clutter, disrupting the uniform roofscape and eroding the building's historic plan form and fabric, with no public benefits to outweigh it. The proposal therefore conflicts with Policies Q11, Q20 and Q22 of the Lambeth Local Plan (2021).

From the council's decision notice.
