DM3.3 Residential conversions and extensions 

To maintain a supply of larger homes to meet Islington’s housing need the conversion of residential units into a larger number of self contained units will normally only be permitted where the total floor area is in excess of 125m2 (gross internal) and the proposed conversion meets the following criteria:

  • the dwelling mix does not include one person-sized units or multiple one double bedroom units, and;
  • at least one unit of two or more bedrooms is provided in conversions of dwellings with between 125m2 and 140m2 of existing floor area, or;
  • at least one three bedroom and one two bedroom unit is provided in conversions of dwellings in excess of 140m2 of existing floor area, unless exceptional circumstances can be demonstrated.

The council will assess the acceptability of proposed conversions which meet the above requirements with regards to the following (in addition to other relevant planning policies):

  • the extent to which the proposal contributes to meeting housing size priorities set out in Table 3.1;
  • the effect on the amenity of adjacent properties through noise, visual intrusion, the position of entrances, extensions and fire escapes;
  • the physical characteristics of the property, including internal layout and the relationship of rooms on different floors within the scheme;
  • the amenity of future occupants; and
  • the effect of any changes to the external appearance of the building.

All conversions must be designed to meet or exceed the minimum housing space standards and Islington’s Accessible Housing SPD, unless exceptional circumstances can be demonstrated.

In line with Policy DM8.5, no additional on-site vehicle parking will be permitted and, unless exceptional circumstances can be demonstrated, no additional parking permits will be issued to any occupiers of additional housing units created through conversions.
