An appeal has been allowed for alterations and extensions to a mid terrace house within a Conservation Area in Islington. The property is a former shop and is locally listed. The proposals included a mansard roof extension, excavation of a semi basement area and insertion of a mezzanine, and an internal rearrangement of the accommodation and staircase. The controversial element of the scheme included a half-width, second floor, rear extension over the new staircase. The Inspector considered that the extension designed by Architects London Atelier, which would be constructed in non-reflective glazing, would allow views of the brickwork behind and be “a small and inconsequential addition to the building”. The character and appearance of the Conservation Area would therefore be unharmed.
